CVE-2022-29181: Apple macOS

High severity, CVSS 8.2. EPSS: 3.2% chance of exploitation in the next 30 days.

Nokogiri is an open source XML and HTML library for Ruby. Nokogiri prior to version 1.13.6 does not type-check all inputs into the XML and HTML4 SAX parsers, allowing specially crafted untrusted inputs to cause illegal memory access errors (segfault) or reads from unrelated memory. Version 1.13.6 contains a patch for this issue. As a workaround, ensure the untrusted input is a `String` by calling `#to_s` or equivalent.

Affected products

• Apple macOS: from 13.0, before 13.1 (fixed in 13.1)
• Nokogiri Nokogiri: before 1.13.6 (fixed in 1.13.6)
