Summary Out-of-bounds Write in zlib affects Nokogiri ## Summary Nokogiri 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. Please note that this advisory only applies to the CRuby implementation of Nokogiri `< 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. ## Mitigation Upgrade to Nokogiri `>= v1.13.4`. ## Impact ### [CVE-2018-25032](https://nvd.nist.gov/vuln/detail/CVE-2018-25032) in zlib - **Severity**: High - **Type**: [CWE-787](https://cwe.mitre.org/data/definitions/787.html) Out of bounds write - **Description**: zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.
