Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Nokogiri versions before 1.13.5, when using the packaged libxml2 on CRuby, are affected by integer overflow flaws in libxml2's buffer handling (CVE-2022-29824). An attacker who can get a victim to open a crafted multi-gigabyte XML file could cause out-of-bounds memory writes, leading to information disclosure or denial of service. Upgrade to Nokogiri 1.13.5 or later.
