Vulnerability from gsd

Details
### Summary Nokogiri `< v1.13.6` does not type-check all inputs into the XML and HTML4 SAX parsers. For CRuby users, this may allow specially crafted untrusted inputs to cause illegal memory access errors (segfault) or reads from unrelated memory. ### Severity The Nokogiri maintainers have evaluated this as **High 8.2** (CVSS3.1). ### Mitigation CRuby users should upgrade to Nokogiri `>= 1.13.6`. JRuby users are not affected. ### Workarounds To avoid this vulnerability in affected applications, ensure the untrusted input is a `String` by calling `#to_s` or equivalent.
