Rack Gem Subject to Denial of Service via Hash Collisions

Rack before 1.1.3, 1.2.x before 1.2.5, and 1.3.x before 1.3.6 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service CPU consumption by sending many crafted parameters...

CVE-2022-23633

A flaw was found in the Rack middleware package of RubyGems, where response bodies will not close under certain circumstances. This flaw allows an attacker to iterate requests to force ActionDispatch::Executor to not close, allowing subsequent requests to leak data from...

Ruby on Rails: ReDoS in Rack::Multipart

A regular expression denial of service ReDoS vulnerability was discovered in the Rack gem's Multipart module. This vulnerability allowed an attacker to cause a denial of service by sending a specially crafted header, resulting in excessive CPU usage on the server. The vulnerability has been patch...

Ruby: ReDoS in Time.rfc2822

A regular expression denial of service ReDoS vulnerability was discovered in the Time.rfc2822 method in Ruby's time library. An attacker could exploit this vulnerability by providing a specially crafted input to the method, causing it to enter an infinite loop and consume excessive CPU resources...

CVE-2022-23634

Puma (Ruby/Rack HTTP server) is affected by CVE-2022-23634 due to not always closing the response body before 5.6.2, which combined with Rails’ Executor implementation could cause information leakage. The issue is fixed in Puma 5.6.2 and 4.3.11; Rails fixes exist in 7.0.2.2, 6.1.4.6, 6.0.4.6, and...

CVE-2022-23634

Puma is a Ruby/Rack web server built for parallelism. Prior to puma version 5.6.2, puma may not always call close on the response body. Rails, prior to version 7.0.2.2, depended on the response body being closed in order for its CurrentAttributes implementation to work correctly. The combination ...

Exposure of information in Action Pack

Impact Under certain circumstances response bodies will not be closed, for example a bug in a webserver or a bug in a Rack middleware. In the event a response is not notified of a close, ActionDispatch::Executor will not know to reset thread local state for the next request. This can lead to data...
