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 – 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-cookiejar

Versions of the package cookiejar before 2.1.4 are vulnerable to Regular Expression Denial of Service ReDoS attacks through the Cookie.parse function, which uses an insecure regular expression...

Astra Linux – Vulnerability in pcre2

A out-of-bounds read vulnerability was discovered in the PCRE2 library, specifically in the pcre2jitcompile.c file’s compilexclassmatchingpath function. This issue relates to a Unicode property matching problem in JIT-compiled regular expressions. The vulnerability arises because the character is...

Astra Linux – Vulnerability in ruby-websocket-extensions

The websocket-extensions Ruby module before version 0.1.5 allowed Denial of Service DoS attacks through Regex backtracking. The extension parser could take quadratic time when parsing a header containing an unclosed string parameter value whose content was a repeated two-byte sequence of a...

Astra Linux – Vulnerability in dovecot

The Sieve engine in Dovecot before 2.3.15 allowed uncontrolled resource consumption, as demonstrated by a situation involving a complex regular expression for the regex extension...

Astra Linux – Vulnerability in python-py

A denial of service attack via regular expressions in the py.path.svnwc component of py also known as python-py in versions up to 1.9.0 could be exploited by attackers to trigger a compute-time denial of service attack by providing malicious input to the blame functionality...

Astra Linux – Vulnerability in Firefox and Thunderbird

When UpdateRegExpStatics attempted to access initialStringHeap, it might have already been garbage collected before entering the function. This could potentially lead to a exploitable crash. This vulnerability affects Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2...

Astra Linux – Vulnerability in pcre2

A out-of-bounds read vulnerability was discovered in the PCRE2 library, specifically in the getrecursedatalength function of the pcre2jitcompile.c file. This issue affects recursions in JIT-compiled regular expressions due to duplicate data transfers...

Astra Linux – Vulnerability in exim4

A vulnerability was discovered in Exim and has been classified as problematic. This issue affects certain aspects of the component Regex Handler’s processing. The vulnerability results in memory leaks after the component is freed from memory. The name of the patch is...

Astra Linux – Vulnerability in node-ssri

ssri 5.2.2-8.0.0; fixed in 8.0.1. This version processes SRIs using a regular expression, which is vulnerable to a denial-of-service attack. Malicious SRIs could take an extremely long time to process, resulting in a denial of service. This issue only affects consumers who use the “strict” option...

Astra Linux – Vulnerability in Ruby 2.5

A issue was discovered in Ruby 3.x through 3.3.0. If data supplied by an attacker is provided to the Ruby regex compiler, it is possible to extract arbitrary heap data relative to the start of the text, including pointers and sensitive strings. The fixed versions are 3.0.7, 3.1.5, 3.2.4, and 3.3....

perl: Perl: Incorrect regular expression processing via large regular expressions

A flaw was found in Perl. When the Perl regular expression engine processes patterns with a very large number of alternative fixed strings, an internal data field can overflow. This leads to silently incorrect regular expression matches, causing the engine to either match strings it should not...
