Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to perform system management tasks.

Security Fix(es):

* rubygem-bundler: Dependencies of gems with explicit source may be installed from a different source (CVE-2020-36327)

* rubygem-rdoc: Command injection vulnerability in RDoc (CVE-2021-31799)

* ruby: FTP PASV command response can cause Net::FTP to connect to arbitrary host (CVE-2021-31810)

* ruby: StartTLS stripping vulnerability in Net::IMAP (CVE-2021-32066)

Affected: Bitnami: ruby

An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. Net::IMAP does not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack."

Affected: CleanStart: ruby

Security vulnerability affects the ruby package. This issue is resolved in later releases. See references for vulnerability details.

Affected: openEuler:20.03-LTS-SP1: ruby, openEuler:20.03-LTS-SP2: ruby

Ruby is a fast and easy interpreted scripting language for object-oriented programming. It has many functions for processing text Files and perform system management tasks (such as Perl). Security Fix(es): In RDoc 3.11 through 6.x before 6.3.1, as distributed with Ruby through 3.0.1, it is possible to execute arbitrary code via | and tags in a filename.(CVE-2021-31799) An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. A malicious FTP server can use the PASV response to trick Net::FTP into connecting back to a given IP address and port. This potentially makes curl extract information about services that are otherwise private and not disclosed (e.g., the attacker can conduct port scans and service banner extractions).(CVE-2021-31810) An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. Net::IMAP does not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack."(CVE-2021-32066)

Affected: Ubuntu:Pro:16.04:LTS: ruby2.3, Ubuntu:18.04:LTS: ruby2.5, Ubuntu:20.04:LTS: ruby2.7

An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1.
