An issue was discovered in phpseclib 1.x before 1.0.23, 2.x before 2.0.47, and 3.x before 3.0.36. When processing the ASN.1 object identifier of a certificate, a sub identifier may be provided that leads to a denial of service (CPU consumption for decodeOID).

cmark-gfm is an extended version of the C reference implementation of CommonMark, a rationalized version of Markdown syntax with a spec. Three polynomial time complexity issues in cmark-gfm may lead to unbounded resource exhaustion and subsequent denial of service. These vulnerabilities have been patched in 0.29.0.gfm.12.

silverstripe-graphql is a package which serves Silverstripe data in GraphQL representations. An attacker could use a recursive graphql query to execute a Distributed Denial of Service attack (DDOS attack) against a website. This mostly affects websites with publicly exposed graphql schemas. If your Silverstripe CMS project does not expose a public facing graphql schema, a user account is required to trigger the DDOS attack. If your site is hosted behind a content delivery network (CDN), such as Imperva or CloudFlare, this may further mitigate the risk. This issue has been addressed in versions 3.8.2, 4.1.3, 4.2.5, 4.3.4, and 5.0.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Affected devices cannot properly process specially crafted Ethernet frames sent to the devices. This could allow an unauthenticated remote attacker to cause a denial of service condition. The affected devices must be restarted manually.

Parsing malicious or large YAML documents can consume excessive amounts of CPU or memory.

Microsoft QUIC Denial of Service Vulnerability

Wings is the control plane software for the open source Pterodactyl game management system. All versions of Pterodactyl Wings prior to `1.4.4` are vulnerable to system resource exhaustion due to improper container process limits being defined. A malicious user can consume more resources than intended and cause downstream impacts to other clients on the same hardware, eventually causing the physical server to stop responding. Users should upgrade to `1.4.4` to mitigate the issue. There is no non-code based workaround for impacted versions of the software. Users running customized versions of this software can manually set a PID limit for containers created.

Rack is a modular Ruby web server interface. Carefully crafted Range headers can cause a server to respond with an unexpectedly large response. Responding with such large responses could lead to a denial of service issue. Vulnerable applications will use the `Rack::File` middleware or the `Rack::Utils.byte_ranges` methods (this includes Rails applications). The vulnerability is fixed in 3.0.9.1 and 2.2.8.1.

OPC UA .NET Standard Stack 1.04.368 allows a remote attacker to exhaust the memory resources of a server via a crafted request that triggers Uncontrolled Resource Consumption.

go-ethereum (geth) is a golang execution layer implementation of the Ethereum protocol. A vulnerable node, can be made to consume unbounded amounts of memory when handling specially crafted p2p messages sent from an attacker node. The fix is included in geth version `1.12.1-stable`, i.e, `1.12.2-unstable` and onwards. Users are advised to upgrade. There are no known workarounds for this vulnerability.

An issue was discovered in Qubo Smart Plug 10A version HSP02_01_01_14_SYSTEM-10A, allows attackers to cause a denial of service (DoS) via Wi-Fi deauthentication.

Eclipse Jetty provides a web server and servlet container. In versions 11.0.0 through 11.0.15, 10.0.0 through 10.0.15, and 9.0.0 through 9.4.52, an integer overflow in `MetaDataBuilder.checkSize` allows for HTTP/2 HPACK header values to exceed their size limit. `MetaDataBuilder.java` determines if a header name or value exceeds the size limit, and throws an exception if the limit is exceeded. However, when length is very large and huffman is true, the multiplication by 4 in line 295 will overflow, and length will become negative. `(_size+length)` will now be negative, and the check on line 296 will not be triggered. Furthermore, `MetaDataBuilder.checkSize` allows for user-entered HPACK header value sizes to be negative, potentially leading to a very large buffer allocation later on when the user-entered size is multiplied by 2. This means that if a user provides a negative length value (or, more precisely, a length value which, when multiplied by the 4/3 fudge factor, is negative), and this length value is a very large positive number when multiplied by 2, then the user can cause a very large buffer to be allocated on the server. Users of HTTP/2 can be impacted by a remote denial of service attack. The issue has been fixed in versions 11.0.16, 10.0.16, and 9.4.53. There are no known workarounds.

Discourse is an open source discussion platform. In affected versions a request to create or update custom sidebar section can cause a denial of service. This issue has been patched in commit `52b003d915`. Users are advised to upgrade. There are no known workarounds for this vulnerability.

An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on MX Series allows a unauthenticated network-based attacker to cause an infinite loop, resulting in a Denial of Service (DoS). An attacker who sends malformed TCP traffic via an interface configured with PPPoE, causes an infinite loop on the respective PFE. This results in consuming all resources and a manual restart is needed to recover. This issue affects interfaces with PPPoE configured and tcp-mss enabled. This issue affects Juniper Networks Junos OS * All versions prior to 20.4R3-S7; * 21.1 version 21.1R1 and later versions; * 21.2 versions prior to 21.2R3-S6; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S3; * 22.1 versions prior to 22.1R3-S4; * 22.2 versions prior to 22.2R3; * 22.3 versions prior to 22.3R2-S2; * 22.4 versions prior to 22.4R2;

HTTP.sys Denial of Service Vulnerability

Yet Another Reverse Proxy (YARP) Denial of Service Vulnerability

Bitcoin Core before 24.1, when debug mode is not used, allows attackers to cause a denial of service (e.g., CPU consumption) because draining the inventory-to-send queue is inefficient, as exploited in the wild in May 2023.

zxcvbn-ts is an open source password strength estimator written in typescript. This vulnerability affects users running on the nodeJS platform which are using the second argument of the zxcvbn function. It can result in an unbounded resource consumption as the user inputs array is extended with every function call. Browsers are impacted, too but a single user need to do a lot of input changes so that it affects the browser, while the node process gets the inputs of every user of a platform and can be killed that way. This problem has been patched in version 3.0.2. Users are advised to upgrade. Users unable to upgrade should stop using the second argument of the zxcvbn function and use the zxcvbnOptions.setOptions function.

libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Using well-crafted inputs to `git_revparse_single` can cause the function to enter an infinite loop, potentially causing a Denial of Service attack in the calling application. The revparse function in `src/libgit2/revparse.c` uses a loop to parse the user-provided spec string. There is an edge-case during parsing that allows a bad actor to force the loop conditions to access arbitrary memory. Potentially, this could also leak memory if the extracted rev spec is reflected back to the attacker. As such, libgit2 versions before 1.4.0 are not affected. Users should upgrade to version 1.6.5 or 1.7.2.

Bramble Synchronisation Protocol (BSP) in Briar before 1.4.22 allows attackers to cause a denial of service (repeated application crashes) via a series of long messages to a contact.
