ruby: Potential HTTP request smuggling in WEBrick

An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy which also has a po...

ruby: StartTLS stripping vulnerability in Net::IMAP

Ruby's Net::IMAP module did not raise an exception when receiving an unexpected response to the STARTTLS command and the connection was not upgraded to use TLS. A man-in-the-middle attacker could use this flaw to prevent Ruby applications using Net::IMAP to enable TLS encryption for a connection ...

ruby: XML round-trip vulnerability in REXML

A flaw was found in the way the Ruby REXML library parsed XML documents. Parsing a specially crafted XML document using REXML and writing parsed data back to a new XML document results in creating a document with a different structure. This issue could affect the integrity of processed data in...

rubygem-rdoc: Command injection vulnerability in RDoc

An operating system command injection flaw was found in RDoc. Using the rdoc command to generate documentation for a malicious Ruby source code could lead to execution of arbitrary commands with the privileges of the user running rdoc...

ruby: Cookie prefix spoofing in CGI::Cookie.parse

A flaw was found in Ruby. RubyGems cgi gem could allow a remote attacker to conduct spoofing attacks caused by the mishandling of security prefixes in cookie names in the CGI::Cookie.parse function. By sending a specially-crafted request, an attacker could perform cookie prefix spoofing attacks...

ruby: Regular expression denial of service vulnerability of Date parsing methods

A flaw was found in ruby, where the date object was found to be vulnerable to a regular expression denial of service ReDoS during the parsing of dates.
