An issue was discovered in Oniguruma 6.x before 6.9.4_rc2. In the function gb18030_mbc_enc_len in file gb18030.c, a UChar pointer is dereferenced without checking if it passed the end of the matched string. This leads to a heap-based buffer over-read.

typed_ast 1.3.0 and 1.3.1 has a handle_keywordonly_args out-of-bounds read. An attacker with the ability to cause a Python interpreter to parse Python source (but not necessarily execute it) may be able to crash the interpreter process. This could be a concern, for example, in a web-based service that parses (but does not execute) Python code. (This issue also affected certain Python 3.8.0-alpha prereleases.)

MediaTek microchips, as used in NETGEAR devices through 2021-11-11 and other devices, mishandle the WPS (Wi-Fi Protected Setup) protocol. (Affected Chipsets MT7603E, MT7610, MT7612, MT7613, MT7615, MT7620, MT7622, MT7628, MT7629, MT7915; Affected Software Versions 7.4.0.0; Out-of-bounds read).

An issue was discovered in Oniguruma 6.x before 6.9.4_rc2. In the function fetch_interval_quantifier (formerly known as fetch_range_quantifier) in regparse.c, PFETCH is called without checking PEND. This leads to a heap-based buffer over-read.

Fetch FTP Client 5.8.2 contains a denial of service vulnerability that allows attackers to trigger 100% CPU consumption by sending long server responses. Attackers can send specially crafted FTP server responses exceeding 2K bytes to cause excessive resource utilization and potentially crash the application.

A denial of service issue was discovered in GitLab CE/EE affecting all versions starting from 13.2.4 before 15.10.8, all versions starting from 15.11 before 15.11.7, all versions starting from 16.0 before 16.0.2 which allows an attacker to cause high resource consumption using malicious test report artifacts.

SOUND4 IMPACT/FIRST/PULSE/Eco versions 2.x contains a network vulnerability that allows unauthenticated attackers to send ICMP signals to arbitrary hosts through network command scripts. Attackers can abuse ping.php, traceroute.php, and dns.php to generate network flooding attacks targeting external hosts.

Vault is vulnerable to a denial-of-service condition where an unauthenticated attacker can repeatedly initiate or cancel root token generation or rekey operations, occupying the single in-progress operation slot. This prevents legitimate operators from completing these workflows. This vulnerability, CVE-2026-5807, is fixed in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0.

Oniguruma through 6.9.3, as used in PHP 7.3.x and other products, has a heap-based buffer over-read in str_lower_case_match in regexec.c.

A memory exhaustion vulnerability exists in the HTTP server due to unbounded use of the `Content-Length` header. The server allocates memory directly based on the attacker supplied header value without enforcing an upper limit. A crafted HTTP request containing an extremely large `Content-Length` value can trigger excessive memory allocation and server termination, even without sending a request body.

The ASN.1 parser in Bouncy Castle Crypto (aka BC Java) 1.63 can trigger a large attempted memory allocation, and resultant OutOfMemoryError error, via crafted ASN.1 data. This is fixed in 1.64.

User-controlled operations could have allowed Denial of Service in M-Files Server before 23.4.12528.1 due to uncontrolled memory consumption.

idreamsoft iCMS 7.0.15 allows remote attackers to cause a denial of service (resource consumption) via a query for many comments, as demonstrated by the admincp.php?app=comment&perpage= substring followed by a large positive integer.

ClamAV versions prior to 0.101.2 are susceptible to a denial of service (DoS) vulnerability. An out-of-bounds heap read condition may occur when scanning PE files. An example is Windows EXE and DLL files that have been packed using Aspack as a result of inadequate bound-checking.

Ubiquiti EdgeMAX devices before 2.0.3 allow remote attackers to cause a denial of service (disk consumption) because *.cache files in /var/run/beaker/container_file/ are created when providing a valid length payload of 249 characters or fewer to the beaker.session.id cookie in a GET header. The attacker can use a long series of unique session IDs.

Varnish Enterprise before 6.0.16r12 allows a "workspace overflow" denial of service (daemon panic) for shared VCL. The headerplus.write_req0() function from vmod_headerplus updates the underlying req0, which is normally the original read-only request from which req is derived (readable and writable from VCL). This is useful in the active VCL, after amending req, to prepare a refined req0 before switching to a different VCL with the return (vcl(<label>)) action. This is for example how the Varnish Controller operates shared VCL deployments. If the amended req contained too many header fields for req0, this would have resulted in a workspace overflow that would in turn trigger a panic and crash the Varnish Enterprise server. This could be used as a Denial of Service attack vector by malicious clients.

Onigmo through 6.2.0 has an out-of-bounds read in parse_char_class because of missing codepoint validation in regenc.c.

RDesktop version 1.8.4 contains multiple out-of-bound access read vulnerabilities in its code, which results in a denial of service (DoS) condition. This attack appear to be exploitable via network connectivity. These issues have been fixed in version 1.8.5

In Puma before versions 3.12.2 and 4.3.1, a poorly-behaved client could use keepalive requests to monopolize Puma's reactor and create a denial of service attack. If more keepalive connections to Puma are opened than there are threads available, additional connections will wait permanently if the attacker sends requests frequently enough. This vulnerability is patched in Puma 4.3.1 and 3.12.2.

Expr is an expression language and expression evaluation for Go. Prior to version 1.17.0, if the Expr expression parser is given an unbounded input string, it will attempt to compile the entire string and generate an Abstract Syntax Tree (AST) node for each part of the expression. In scenarios where input size isn’t limited, a malicious or inadvertent extremely large expression can consume excessive memory as the parser builds a huge AST. This can ultimately lead to*excessive memory usage and an Out-Of-Memory (OOM) crash of the process. This issue is relatively uncommon and will only manifest when there are no restrictions on the input size, i.e. the expression length is allowed to grow arbitrarily large. In typical use cases where inputs are bounded or validated, this problem would not occur. The problem has been patched in the latest versions of the Expr library. The fix introduces compile-time limits on the number of AST nodes and memory usage during parsing, preventing any single expression from exhausting resources. Users should upgrade to Expr version 1.17.0 or later, as this release includes the new node budget and memory limit safeguards. Upgrading to v1.17.0 ensures that extremely deep or large expressions are detected and safely aborted during compilation, avoiding the OOM condition. For users who cannot immediately upgrade, the recommended workaround is to impose an input size restriction before parsing. In practice, this means validating or limiting the length of expression strings that your application will accept. For example, set a maximum allowable number of characters (or nodes) for any expression and reject or truncate inputs that exceed this limit. By ensuring no unbounded-length expression is ever fed into the parser, one can prevent the parser from constructing a pathologically large AST and avoid potential memory exhaustion. In short, pre-validate and cap input size as a safeguard in the absence of the patch.

In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.

An issue was discovered in GitLab Community and Enterprise Edition through 12.2.1. Under certain circumstances, CI pipelines could potentially be used in a denial of service attack.

EMQ X Broker versions prior to 4.2.8 are vulnerable to a denial of service attack as a result of excessive memory consumption due to the handling of untrusted inputs. These inputs cause the message broker to consume large amounts of memory, resulting in the application being terminated by the operating system.

An issue was discovered in GitLab Community and Enterprise Edition 8.15 through 12.2.1. Particular mathematical expressions in GitLab Markdown can exhaust client resources.

jsPDF is a library to generate PDFs in JavaScript. Prior to 3.0.1, user control of the first argument of the addImage method results in CPU utilization and denial of service. If given the possibility to pass unsanitised image urls to the addImage method, a user can provide a harmful data-url that results in high CPU utilization and denial of service. Other affected methods are html and addSvgAsImage. The vulnerability was fixed in jsPDF 3.0.1.

In mpg123 1.25.0, there is a heap-based buffer over-read in the convert_latin1 function in libmpg123/id3.c. A crafted input will lead to a remote denial of service attack.

SHAREit through 4.0.6.177 does not check the full message length from the received packet header (which is used to allocate memory for the next set of data). This could lead to a system denial of service due to uncontrolled memory allocation. This is different from CVE-2019-14941.

An issue was discovered in the simd-json crate before 0.1.15 for Rust. There is an out-of-bounds read and an incorrect crossing of a page boundary.

We have already fixed the vulnerability in the following version: File Station 5 5.5.6.4847 and later

JSON is a JSON implementation for Ruby. Starting in version 2.10.0 and prior to version 2.10.2, a specially crafted document could cause an out of bound read, most likely resulting in a crash. Versions prior to 2.10.0 are not vulnerable. Version 2.10.2 fixes the problem. No known workarounds are available.

mq_parse_http in mongoose.c in Mongoose 6.15 has a heap-based buffer over-read.

Vulnerability in the RCPbind service running on UDP port (111), allowing a remote attacker to create a denial of service (DoS) condition.

A gzip decompression bomb vulnerability exists when Orthanc processes HTTP request with `Content-Encoding: gzip`. The server does not enforce limits on decompressed size and allocates memory based on attacker-controlled compression metadata. A specially crafted gzip payload can trigger excessive memory allocation and exhaust system memory.

VerneMQ MQTT Broker versions prior to 1.12.0 are vulnerable to a denial of service attack as a result of excessive memory consumption due to the handling of untrusted inputs. These inputs cause the message broker to consume large amounts of memory, resulting in the application being terminated by the operating system.

ReadJXLImage in JXL in GraphicsMagick before 1.3.46 lacks image dimension resource limits.

Transient DOS while handling beacon frames with invalid IE header length.

Configuration defects in the secure OS module.Successful exploitation of this vulnerability will affect availability.

An issue was discovered in Django 5.1 before 5.1.8 and 5.0 before 5.0.14. The NFKC normalization is slow on Windows. As a consequence, django.contrib.auth.views.LoginView, django.contrib.auth.views.LogoutView, and django.views.i18n.set_language are subject to a potential denial-of-service attack via certain inputs with a very large number of Unicode characters.

OpenTelemetry dotnet is a dotnet telemetry framework. A vulnerability in OpenTelemetry.Api package 1.10.0 to 1.11.1 could cause a Denial of Service (DoS) when a tracestate and traceparent header is received. Even if an application does not explicitly use trace context propagation, receiving these headers can still trigger high CPU usage. This issue impacts any application accessible over the web or backend services that process HTTP requests containing a tracestate header. Application may experience excessive resource consumption, leading to increased latency, degraded performance, or downtime. This vulnerability is fixed in 1.11.2.
