{"id":"GHSA-v6gp-9mmm-c6p5","summary":"Out-of-bounds Write in zlib affects Nokogiri","details":"## Summary\n\nNokogiri v1.13.4 updates the vendored zlib from 1.2.11 to 1.2.12, which addresses [CVE-2018-25032](https://nvd.nist.gov/vuln/detail/CVE-2018-25032). That CVE is scored as CVSS 7.4 \"High\" on the NVD record as of 2022-04-05.\n\nPlease note that this advisory only applies to the CRuby implementation of Nokogiri `\u003c 1.13.4`, and only if the packaged version of `zlib` is being used. Please see [this document](https://nokogiri.org/LICENSE-DEPENDENCIES.html#default-platform-release-ruby) for a complete description of which platform gems vendor `zlib`. If you've overridden defaults at installation time to use system libraries instead of packaged libraries, you should instead pay attention to your distro's `zlib` release announcements. \n\n## Mitigation\n\nUpgrade to Nokogiri `\u003e= v1.13.4`.\n\n## Impact\n\n### [CVE-2018-25032](https://nvd.nist.gov/vuln/detail/CVE-2018-25032) in zlib\n\n- **Severity**: High\n- **Type**: [CWE-787](https://cwe.mitre.org/data/definitions/787.html) Out of bounds write\n- **Description**: zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.\n\n","modified":"2024-12-05T05:39:12.688270Z","published":"2022-04-11T21:21:28Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2022-04-11T21:21:28Z","nvd_published_at":null,"cwe_ids":["CWE-787"]},"references":[{"type":"WEB","url":"https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-v6gp-9mmm-c6p5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-25032"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-jc36-42cf-vqwj"},{"type":"PACKAGE","url":"https://github.com/sparklemotion/nokogiri"},{"type":"WEB","url":"https://github.com/sparklemotion/nokogiri/releases/tag/v1.13.4"},{"type":"WEB","url":"https://groups.google.com/g/ruby-security-ann/c/vX7qSjsvWis/m/TJWN4oOKBwAJ?utm_medium=email&utm_source=footer"}],"affected":[{"package":{"name":"nokogiri","ecosystem":"RubyGems","purl":"pkg:gem/nokogiri"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.13.4"}]}],"versions":["1.0.0","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5","1.0.6","1.0.7","1.1.0","1.1.1","1.10.0","1.10.0.rc1","1.10.1","1.10.10","1.10.2","1.10.3","1.10.4","1.10.5","1.10.6","1.10.7","1.10.8","1.10.9","1.11.0","1.11.0.rc1","1.11.0.rc2","1.11.0.rc3","1.11.0.rc4","1.11.1","1.11.2","1.11.3","1.11.4","1.11.5","1.11.6","1.11.7","1.12.0","1.12.0.rc1","1.12.1","1.12.2","1.12.3","1.12.4","1.12.5","1.13.0","1.13.1","1.13.2","1.13.3","1.2.0","1.2.1","1.2.2","1.2.3","1.3.0","1.3.1","1.3.2","1.3.3","1.4.0","1.4.1","1.4.2","1.4.2.1","1.4.3","1.4.3.1","1.4.4","1.4.4.1","1.4.4.2","1.4.5","1.4.6","1.4.7","1.5.0","1.5.0.beta.1","1.5.0.beta.2","1.5.0.beta.3","1.5.0.beta.4","1.5.1","1.5.1.rc1","1.5.10","1.5.11","1.5.2","1.5.3","1.5.3.rc2","1.5.3.rc3","1.5.3.rc4","1.5.3.rc5","1.5.3.rc6","1.5.4","1.5.4.rc1","1.5.4.rc2","1.5.4.rc3","1.5.5","1.5.5.rc1","1.5.5.rc2","1.5.5.rc3","1.5.6","1.5.6.rc1","1.5.6.rc2","1.5.6.rc3","1.5.7","1.5.7.rc1","1.5.7.rc2","1.5.7.rc3","1.5.8","1.5.9","1.6.0","1.6.0.rc1","1.6.1","1.6.2","1.6.2.1","1.6.2.rc1","1.6.2.rc2","1.6.2.rc3","1.6.3","1.6.3.1","1.6.3.rc1","1.6.3.rc2","1.6.3.rc3","1.6.4","1.6.4.1","1.6.5","1.6.6.1","1.6.6.2","1.6.6.3","1.6.6.4","1.6.7","1.6.7.1","1.6.7.2","1.6.7.rc2","1.6.7.rc3","1.6.7.rc4","1.6.8","1.6.8.1","1.6.8.rc1","1.6.8.rc2","1.6.8.rc3","1.7.0","1.7.0.1","1.7.1","1.7.2","1.8.0","1.8.1","1.8.2","1.8.3","1.8.4","1.8.5","1.9.0","1.9.0.rc1","1.9.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/04/GHSA-v6gp-9mmm-c6p5/GHSA-v6gp-9mmm-c6p5.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
