Nokogiri is an open source XML and HTML library for the Ruby programming language. Nokogiri `1.13.8` and `1.13.9` fail to check the return value from `xmlTextReaderExpand` in the method `Nokogiri::XML::Reader#attribute_hash`. This can lead to a null pointer exception when invalid markup is being parsed. For applications using `XML::Reader` to parse untrusted inputs, this may potentially be a vector for a denial of service attack. Users are advised to upgrade to Nokogiri `>= 1.13.10`. Users may be able to search their code for calls to either `XML::Reader#attributes` or `XML::Reader#attribute_hash` to determine if they are affected.Show less

An Unchecked Return Value to NULL Pointer Dereference vulnerability in Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). In Segment Routing (SR) to Label Distribution Protocol (LDP) interworking scenario, configured with Segment Routing Mapping Server (SRMS) at any node, when an Area Border Router (ABR) leaks the SRMS entries having "S" flag set from IS-IS Level 2 to Level 1, an rpd core might be observed when a specific low privileged CLI command is issued. This issue affects: Juniper Networks Junos OS 21.4 versions prior to 21.4R1-S2, 21.4R2-S1, 21.4R3; 22.1 versions prior to 22.1R2. Juniper Networks Junos OS Evolved 21.4-EVO versions prior to 21.4R1-S2-EVO, 21.4R2-S1-EVO, 21.4R3-EVO; 22.1-EVO versions prior to 22.1R2-EVO. This issue does not affect: Juniper Networks Junos OS versions prior to 21.4R1. Juniper Networks Junos OS Evolved versions prior to 21.4R1-EVO.Show less

A flaw was found in Undertow. For an AJP 400 response, EAP 7 is improperly sending two response packets, and those packets have the reuse flag set even though JBoss EAP closes the connection. A failure occurs when the connection is reused after a 400 by CPING since it reads in the second SEND_HEADERS response packet instead of a CPONG.Show less

A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible.Show less

OpenZeppelin Contracts is a library for smart contract development. Versions 4.0.0 until 4.7.1 are vulnerable to ERC165Checker reverting instead of returning `false`. `ERC165Checker.supportsInterface` is designed to always successfully return a boolean, and under no circumstance revert. However, an incorrect assumption about Solidity 0.8's `abi.decode` allows some cases to revert, given a target contract that doesn't implement EIP-165 as expected, specifically if it returns a value other than 0 or 1. The contracts that may be affected are those that use `ERC165Checker` to check for support for an interface and then handle the lack of support in a way other than reverting. The issue was patched in version 4.7.1.Show less

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. In affected versions certain types of invalid files requests are not handled properly and can crash the server. If you are running multiple Parse Server instances in a cluster, the availability impact may be low; if you are running Parse Server as single instance without redundancy, the availability impact may be high. This issue has been addressed in versions 4.10.12 and 5.2.3. Users are advised to upgrade. There are no known workarounds for this issue.Show less
