nginx: NGINX: Arbitrary code execution via crafted HTTP requests

A flaw was found in NGINX. An unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP requests when the map directive uses regular expression regex matching and references regex capture variables before referencing the map output variable. This can lead to a heap...

Astra Linux – Vulnerabilities in Firefox, Thunderbird, Rust-Regex

Regex is an implementation of regular expressions for the Rust language. The regex crate includes built-in measures to prevent denial-of-service attacks caused by untrusted regexes or untrusted inputs matched by trusted regexes. These measures already provide reasonable defaults to prevent attack...

Astra Linux – Vulnerability in JRuby

In Ruby, WEBrick::HTTPAuth::DigestAuth from versions 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 causes a denial-of-service attack due to a regular expression issue related to looping/backtracking. A victim must expose a WEBrick server that uses DigestAuth to the internet or a trusted...

Astra Linux – Vulnerability in node-path-to-regexp

“path-to-regexp” converts path strings into regular expressions. In some cases, this function may produce regular expressions that can cause poor performance. Since JavaScript is single-threaded, and regex matching occurs on the main thread, poor performance can block the event loop and lead to a...

Astra Linux – Vulnerability found in Python 3.11, Python 2.7, Python 3.7, and Pypy
