An update for ruby is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1306 Final 1.0 1.0 2021-08-06 Initial 2021-08-06 2021-08-06 openEuler SA Tool V1.0 2021-08-06 ruby security update An update for ruby is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. 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) An update for ruby is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. openEuler Security has rated this update as having a security impact of high.
