1.13.5 / 2022-05-04

Security

• [CRuby] Vendored libxml2 is updated to address CVE-2022-29824. See GHSA-cgx6-hpwq-fhv5 for more information.

Dependencies

• [CRuby] Vendored libxml2 is updated from v2.9.13 to v2.9.14.

Improvements

• [CRuby] The libxml2 HTML4 parser no longer exhibits quadratic behavior when recovering some broken markup related to start-of-tag and bare < characters.

Changed

• [CRuby] The libxml2 HTML4 parser in v2.9.14 recovers from some broken markup differently. Notably, the XML CDATA escape sequence <![CDATA[ and incorrectly-opened comments will result in HTML text nodes starting with <! instead of skipping the invalid tag. This behavior is a direct result of the quadratic-behavior fix noted above. The behavior of downstream sanitizers relying on this behavior will also change. Some tests describing the changed behavior are in test/html4/test_comments.rb.
