Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. Carefully crafted content type headers can cause Rack’s media type parser to take much longer than expected, leading to a possible denial-of-service vulnerability ReDos, degree 2 polynomial. This vulnerability has been fixed in 3.0.9.1 and 2.2.8.1...

Astra Linux – Vulnerability in Ruby 2.5

In Ruby, the CGI::Cookie.parse method used from version 2.6.8 mishandles security prefixes in cookie names. This issue also affects the CGI gem used from version 0.3.0 in Ruby...

Astra Linux – Vulnerability in Ruby2.5, JRuby

A issue was discovered in Ruby between versions 2.6.7, 2.7.x up to 2.7.3, and 3.x up to 3.0.1. The Net::IMAP library does not raise an exception when the StartTLS command fails with an unknown response. This may allow man-in-the-middle attackers to bypass TLS protections by leveraging the network...

Astra Linux – Vulnerability in Ruby 2.5, JRuby

A issue was discovered in Ruby between versions 2.6.7, 2.7.x up to 2.7.3, and 3.x up to 3.0.1. A malicious FTP server can use the PASV response to trick Net::FTP into connecting back to a specified IP address and port. This potentially allows curl to extract information about services that would...

Astra Linux – Vulnerability in Puma

Puma is a simple, fast, multi-threaded, parallel HTTP 1.1 server for Ruby/Rack applications. When using Puma behind a proxy that does not properly validate that the incoming HTTP requests comply with the RFC7230 standard, Puma and the frontend proxy may disagree about where the requests start and...

Astra Linux – Vulnerability in ruby-rails-html-sanitizer

Rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Versions starting from 1.0.3 and before 1.4.4 are vulnerable to cross-site scripting through data URIs when used in conjunction with Loofah version 2.1.0 or higher. This issue has been fixed in version 1.4.4...

Astra Linux – Vulnerability in ruby-loofah

Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri.

Astra Linux – Vulnerability in yajl

In the yajl-ruby gem version 1.3.0 for Ruby, when a properly crafted JSON file is provided to Yajl::Parser.new.parse, the entire Ruby process crashes with a SIGABRT in the yajlstringdecode function in yajlencode.c. This causes the entire Ruby process to terminate, potentially leading to a denial ...

Astra Linux – Vulnerability in Ruby-Rack

There is a DoS vulnerability in Rack versions v3.0.4.2, v2.2.6.3, v2.1.4.3, and v2.0.9.3, particularly in the Multipart MIME parsing code. This vulnerability could allow an attacker to craft requests that can be abused to cause the multipart parsing to take longer than expected...

Astra Linux – Vulnerability in Ruby-Nokogiri

Nokogiri is a Rubygem that provides HTML, XML, SAX, and Reader parsers, with support for XPath and CSS selectors. In Nokogiri versions prior to 1.11.0.rc4, there was an XXE vulnerability. XML schemas parsed by Nokogiri::XML::Schema are trusted by default, allowing external resources to be accesse...

Astra Linux – Vulnerability in JRuby

A vulnerability was discovered in Ruby versions 2.5.8, 2.6.x up to 2.6.6, and 2.7.x up to 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, did not rigorously check the transfer-encoding header value. An attacker could potentially exploit this vulnerability to bypass a reverse proxy which...

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 Ruby 2.5

REXML is an XML toolkit for Ruby. The REXML gem before version 3.3.6 has a DoS vulnerability when it parses XMLs that contain many elements with the same local name attribute. If you need to parse untrusted XMLs using tree parser APIs like REXML::Document.new, you may be vulnerable to this...
