{"id":"UBUNTU-CVE-2022-29181","details":"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.","modified":"2026-01-30T02:45:21.128976Z","published":"2022-05-20T19:15:00Z","related":["USN-7659-1"],"upstream":["CVE-2022-29181"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-29181"},{"type":"REPORT","url":"https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-xh29-r2w5-wx8m"},{"type":"REPORT","url":"https://github.com/sparklemotion/nokogiri/commit/83cc451c3f29df397caa890afc3b714eae6ab8f7"},{"type":"REPORT","url":"https://github.com/sparklemotion/nokogiri/commit/db05ba9a1bd4b90aa6c76742cf6102a7c7297267"},{"type":"REPORT","url":"https://github.com/sparklemotion/nokogiri/releases/tag/v1.13.6"},{"type":"REPORT","url":"https://securitylab.github.com/advisories/GHSL-2022-031_GHSL-2022-032_Nokogiri/"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-29181"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7659-1"}],"affected":[{"package":{"name":"ruby-nokogiri","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/ruby-nokogiri@1.10.7+dfsg1-2ubuntu0.1~esm2?arch=source&distro=esm-apps/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.10.7+dfsg1-2ubuntu0.1~esm2"}]}],"versions":["1.10.3+dfsg1-2","1.10.4+dfsg1-1","1.10.7+dfsg1-1","1.10.7+dfsg1-2","1.10.7+dfsg1-2build1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"1.10.7+dfsg1-2ubuntu0.1~esm2","binary_name":"ruby-nokogiri"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-29181.json"}},{"package":{"name":"ruby-nokogiri","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/ruby-nokogiri@1.13.1+dfsg-2ubuntu0.1~esm1?arch=source&distro=esm-apps/jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.13.1+dfsg-2ubuntu0.1~esm1"}]}],"versions":["1.11.1+dfsg-2ubuntu1","1.11.7+dfsg-3","1.11.7+dfsg-3build1","1.13.1+dfsg-2"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_version":"1.13.1+dfsg-2ubuntu0.1~esm1","binary_name":"ruby-nokogiri"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-29181.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
