GitLab 8.11 through 12.8.1 allows a Denial of Service when using several features to recursively request eachother,
regexp.Compile in Go before 1.16.15 and 1.17.x before 1.17.8 allows stack exhaustion via a deeply nested expression.
encoding/pem in Go before 1.17.9 and 1.18.x before 1.18.1 has a Decode stack overflow via a large amount of PEM data.
Jsonxx or Json++ is a JSON parser, writer and reader written in C++. In affected versions of jsonxx json parsing may lead to stack exhaustion in an address sanitized (ASAN) build. This issue may lead to Denial of Service if the program using the jsonxx library crashes. This issue exists on the current commit of the jsonxx project and the project itself has been archived. Updates are not expected. Users are advised to find a replacement.
Tensorflow is an Open Source Machine Learning Framework. The `GraphDef` format in TensorFlow does not allow self recursive functions. The runtime assumes that this invariant is satisfied. However, a `GraphDef` containing a fragment such as the following can be consumed when loading a `SavedModel`. This would result in a stack overflow during execution as resolving each `NodeDef` means resolving the function itself and its nodes. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.
In 0.9.3 or older versions of Apache Pinot segment upload path allowed segment directories to be imported into pinot tables. In pinot installations that allow open access to the controller a specially crafted request can potentially be exploited to cause disruption in pinot service. Pinot release 0.10.0 fixes this. See https://docs.pinot.apache.org/basics/releases/0.10.0
Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Loofah >= 2.2.0, < 2.19.1 uses recursion for sanitizing CDATA sections, making it susceptible to stack exhaustion and raising a SystemStackError exception. This may lead to a denial of service through CPU resource consumption. This issue is patched in version 2.19.1. Users who are unable to upgrade may be able to mitigate this vulnerability by limiting the length of the strings that are sanitized.
TYPO3 is an open source PHP based web content management system. In versions prior to 9.5.38, 10.4.33, 11.5.20, and 12.1.1, requesting invalid or non-existing resources via HTTP triggers the page error handler, which again could retrieve content to be shown as an error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack until the limits of the web server are exceeded. This vulnerability is very similar, but not identical, to the one described in CVE-2021-21359. This issue is patched in versions 9.5.38 ELTS, 10.4.33, 11.5.20 or 12.1.1.
A Denial of Service vulnerability related to stack exhaustion has been identified in FlexNet Publisher lmadmin.exe 11.16.2. Because the message reading function calls itself recursively given a certain condition in the received message, an unauthenticated remote attacker can repeatedly send messages of that type to cause a stack exhaustion condition.
php-svg-lib is an SVG file parsing / rendering library. Prior to version 0.5.1, when parsing the attributes passed to a `use` tag inside an svg document, an attacker can cause the system to go to an infinite recursion. Depending on the system configuration and attack pattern this could exhaust the memory available to the executing process and/or to the server itself. An attacker sending multiple request to a system to render the above payload can potentially cause resource exhaustion to the point that the system is unable to handle incoming request. Version 0.5.1 contains a patch for this issue.
Remarshal prior to v0.17.1 expands YAML alias nodes unlimitedly, hence Remarshal is vulnerable to Billion Laughs Attack. Processing untrusted YAML files may cause a denial-of-service (DoS) condition.
An issue was discovered in Foxit PhantomPDF before 8.3.12. It allows stack consumption via nested function calls for XML parsing.
An issue was discovered in Foxit Reader and PhantomPDF before 9.7. It allows stack consumption via nested function calls for XML parsing.
A Denial Of Service vulnerability exists in the safe-svg (aka Safe SVG) plugin through 1.9.4 for WordPress, related to unlimited recursion for a '<use ... xlink:href="#identifier">' substring.
Foxit Reader 9.6.0.25114 and earlier has two unique RecursiveCall bugs involving 3 functions exhausting available stack memory because of Uncontrolled Recursion in the V8 JavaScript engine (issue 2 of 2).
Any project that parses untrusted Protocol Buffers data containing an arbitrary number of nested groups / series of SGROUP tags can corrupted by exceeding the stack limit i.e. StackOverflow. Parsing nested groups as unknown fields with DiscardUnknownFieldsParser or Java Protobuf Lite parser, or against Protobuf map fields, creates unbounded recursions that can be abused by an attacker.
A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the environment and library usage.
Akka HTTP 10.1.x before 10.1.15 and 10.2.x before 10.2.7 can encounter stack exhaustion while parsing HTTP headers, which allows a remote attacker to conduct a Denial of Service attack by sending a User-Agent header with deeply nested comments.
ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4.
Uncontrolled Recursion in the Bluetooth DHT dissector in Wireshark 3.4.0 to 3.4.9 and 3.2.0 to 3.2.17 allows denial of service via packet injection or crafted capture file
In Mcrouter prior to v0.41.0, a large struct input provided to the Carbon protocol reader could result in stack exhaustion and denial of service.
An issue was discovered in Foxit PDF Reader before 11.0.1 and PDF Editor before 11.0.1. It allows stack consumption during recursive processing of embedded XML nodes.
HTTP2ToRawGRPCServerCodec in gRPC Swift 1.1.1 and earlier allows remote attackers to deny service via the delivery of many small messages within a single HTTP/2 frame, leading to Uncontrolled Recursion and stack consumption.
In Moodle, the file repository's URL parsing required additional recursion handling to mitigate the risk of recursion denial of service.
An issue was discovered in Foxit Reader and PhantomPDF before 10.1.4. It allows stack consumption via recursive function calls during the handling of XFA forms or link objects.
The serde-json-wasm crate before 1.0.1 for Rust allows stack consumption via deeply nested JSON data.
A vulnerability was found in Undertow, where the chunked response hangs after the body was flushed. The response headers and body were sent but the client would continue waiting as Undertow does not send the expected 0\r\n termination of the chunked response. This results in uncontrolled resource consumption, leaving the server side to a denial of service attack. This happens only with Java 17 TLSv1.3 scenarios.
A security issue was found in Netplex Json-smart 2.5.0 through 2.5.1. When loading a specially crafted JSON input, containing a large number of ’{’, a stack exhaustion can be trigger, which could allow an attacker to cause a Denial of Service (DoS). This issue exists because of an incomplete fix for CVE-2023-1370.
A Stack Overflow vulnerability was discovered in the TON Virtual Machine (TVM) before v2024.10. The vulnerability stems from the improper handling of vmstate and continuation jump instructions, which allow for continuous dynamic tail calls. An attacker can exploit this by crafting a smart contract with deeply nested jump logic. Even within permissible gas limits, this nested execution exhausts the host process's stack space, causing the validator node to crash. This results in a Denial of Service (DoS) for the TON blockchain network.
An issue was discovered in the _asn1_decode_simple_ber function in decoding.c in GNU Libtasn1 before 4.13. Unlimited recursion in the BER decoder leads to stack exhaustion and DoS.
An exploitable denial-of-service vulnerability exists in the mdnscap binary of the CUJO Smart Firewall running firmware 7003. When parsing labels in mDNS packets, the firewall unsafely handles label compression pointers, leading to an uncontrolled recursion that eventually exhausts the stack, crashing the mdnscap process. An unauthenticated attacker can send an mDNS message to trigger this vulnerability.
A flaw was discovered in GNU libiberty within demangle_path() in rust-demangle.c, as distributed in GNU Binutils version 2.36. A crafted symbol can cause stack memory to be exhausted leading to a crash.
Uncontrolled recursion in the json2pb component in Apache bRPC (version < 1.15.0) on all platforms allows remote attackers to make the server crash via sending deep recursive json data. Root Cause: The bRPC json2pb component uses rapidjson to parse json data from the network. The rapidjson parser uses a recursive parsing method by default. If the input json has a large depth of recursive structure, the parser function may run into stack overflow. Affected Scenarios: Use bRPC server with protobuf message to serve http+json requests from untrusted network. Or directly use JsonToProtoMessage to convert json from untrusted input. How to Fix: (Choose one of the following options) 1. Upgrade bRPC to version 1.15.0, which fixes this issue. 2. Apply this patch: https://github.com/apache/brpc/pull/3099 Note: No matter which option you choose, you should know that the fix introduces a recursion depth limit with default value 100. It affects these functions: ProtoMessageToJson, ProtoMessageToProtoJson, JsonToProtoMessage, and ProtoJsonToProtoMessage. If your requests contain json or protobuf messages that have a depth exceeding the limit, the request will be failed after applying the fix. You can modify the gflag json2pb_max_recursion_depth to change the limit.
uBlock Origin before 1.36.2 and nMatrix before 4.4.9 support an arbitrary depth of parameter nesting for strict blocking, which allows crafted web sites to cause a denial of service (unbounded recursion that can trigger memory consumption and a loss of all blocking functionality).
Apollo Federation is an architecture for declaratively composing APIs into a unified graph. Each team can own their slice of the graph independently, empowering them to deliver autonomously and incrementally. Instances of @apollo/query-planner >=2.0.0 and <2.8.5 are impacted by a denial-of-service vulnerability. @apollo/gateway versions >=2.0.0 and < 2.8.5 and Apollo Router <1.52.1 are also impacted through their use of @apollo/query-panner. If @apollo/query-planner is asked to plan a sufficiently complex query, it may loop infinitely and never complete. This results in unbounded memory consumption and either a crash or out-of-memory (OOM) termination. This issue can be triggered if you have at least one non-@key field that can be resolved by multiple subgraphs. To identify these shared fields, the schema for each subgraph must be reviewed. The mechanism to identify shared fields varies based on the version of Federation your subgraphs are using. You can check if your subgraphs are using Federation 1 or Federation 2 by reviewing their schemas. Federation 2 subgraph schemas will contain a @link directive referencing the version of Federation being used while Federation 1 subgraphs will not. For example, in a Federation 2 subgraph, you will find a line like @link(url: "https://specs.apollo.dev/federation/v2.0"). If a similar @link directive is not present in your subgraph schema, it is using Federation 1. Note that a supergraph can contain a mix of Federation 1 and Federation 2 subgraphs. This issue results from the Apollo query planner attempting to use a Number exceeding Javascript’s Number.MAX_VALUE in some cases. In Javascript, Number.MAX_VALUE is (2^1024 - 2^971). When the query planner receives an inbound graphql request, it breaks the query into pieces and for each piece, generates a list of potential execution steps to solve the piece. These candidates represent the steps that the query planner will take to satisfy the pieces of the larger query. As part of normal operations, the query planner requires and calculates the number of possible query plans for the total query. That is, it needs the product of the number of query plan candidates for each piece of the query. Under normal circumstances, after generating all query plan candidates and calculating the number of all permutations, the query planner moves on to stack rank candidates and prune less-than-optimal options. In particularly complex queries, especially those where fields can be solved through multiple subgraphs, this can cause the number of all query plan permutations to balloon. In worst-case scenarios, this can end up being a number larger than Number.MAX_VALUE. In Javascript, if Number.MAX_VALUE is exceeded, Javascript represents the value as “infinity”. If the count of candidates is evaluated as infinity, the component of the query planner responsible for pruning less-than-optimal query plans does not actually prune candidates, causing the query planner to evaluate many orders of magnitude more query plan candidates than necessary. This issue has been addressed in @apollo/query-planner v2.8.5, @apollo/gateway v2.8.5, and Apollo Router v1.52.1. Users are advised to upgrade. This issue can be avoided by ensuring there are no fields resolvable from multiple subgraphs. If all subgraphs are using Federation 2, you can confirm that you are not impacted by ensuring that none of your subgraph schemas use the @shareable directive. If you are using Federation 1 subgraphs, you will need to validate that there are no fields resolvable by multiple subgraphs.
OPC Foundation UA .NET Standard versions prior to 1.4.365.48 and OPC UA .NET Legacy are vulnerable to an uncontrolled recursion, which may allow an attacker to trigger a stack overflow.
An issue was discovered in OSSEC 3.6.0. An uncontrolled recursion vulnerability in os_xml.c occurs when a large number of opening and closing XML tags is used. Because recursion is used in _ReadElem without restriction, an attacker can trigger a segmentation fault once unmapped memory is reached.
The Miniscript (aka rust-miniscript) library before 12.2.0 for Rust allows stack consumption because it does not properly track tree depth.
Passing a heavily nested list to sqlparse.parse() leads to a Denial of Service due to RecursionError.
matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. A malicious homeserver can craft a room or room structure such that the predecessors form a cycle. The matrix-js-sdk's getRoomUpgradeHistory function will infinitely recurse in this case, causing the code to hang. This method is public but also called by the 'leaveRoomChain()' method, so leaving a room will also trigger the bug. This was patched in matrix-js-sdk 34.3.1.
TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 9.5.25, 10.4.14, 11.1.1 requesting invalid or non-existing resources via HTTP triggers the page error handler which again could retrieve content to be shown as error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack until the limits of the web server are exceeded. This is fixed in versions 9.5.25, 10.4.14, 11.1.1.
The SMB parser in tcpdump before 4.9.3 has stack exhaustion in smbutil.c:smb_fdata() via recursion.
The BGP parser in tcpdump before 4.9.3 allows stack consumption in print-bgp.c:bgp_attr_print() because of unlimited recursion.
Uncontrolled Recursion in pdfinfo, and pdftops in poppler 0.89.0 allows remote attackers to cause a denial of service via crafted input.
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.9 before 18.9.2 that could have allowed an unauthenticated user to cause a denial of service by sending specially crafted GraphQL requests due to uncontrolled recursion under certain circumstances.
A denial-of-service (DoS) vulnerability exists in google.protobuf.json_format.ParseDict() in Python, where the max_recursion_depth limit can be bypassed when parsing nested google.protobuf.Any messages. Due to missing recursion depth accounting inside the internal Any-handling logic, an attacker can supply deeply nested Any structures that bypass the intended recursion limit, eventually exhausting Python’s recursion stack and causing a RecursionError.
A vulnerability in OpenSearch allows attackers to cause Denial of Service (DoS) by submitting complex query_string inputs. This issue affects all OpenSearch versions between 3.0.0 and < 3.3.0 and OpenSearch < 2.19.4.
In Faust 2.23.1, an input file with the lines "// r visualisation tCst" and "//process = +: L: abM-^Q;" and "process = route(3333333333333333333,2,1,2,3,1) : *;" leads to stack consumption.
A Denial of Service (DoS) vulnerability was discovered in the TON Lite Server before v2024.09. The vulnerability arises from the handling of external arguments passed to locally executed "get methods." An attacker can inject a constructed Continuation object (an internal TVM type) that is normally restricted within the VM. When the TVM executes this malicious continuation, it consumes excessive CPU resources while accruing disproportionately low virtual gas costs. This "free" computation allows an attacker to monopolize the Lite Server's processing power, significantly reducing its throughput and causing a denial of service for legitimate users acting through the gateway.
A flaw was found when using samba as an Active Directory Domain Controller. Due to the way samba handles certain requests as an Active Directory Domain Controller LDAP server, an unauthorized user can cause a stack overflow leading to a denial of service. The highest threat from this vulnerability is to system availability. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2.
