{"id":"ALSA-2026:90495","summary":"Important: brotli security update","details":"Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.   \n\nSecurity Fix(es):  \n\n  * brotli: Out-of-Bounds Write in Google Brotli Decoder (CVE-2026-111497)\n\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.\n","modified":"2026-10-27T01:30:03.952725545Z","published":"2026-10-26T00:00:00Z","related":["CVE-2026-111497"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:90495"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2026-111497"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2558973"},{"type":"ADVISORY","url":"https://errata.almalinux.org/9/ALSA-2026-90495.html"}],"affected":[{"package":{"name":"brotli","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/brotli"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.9-10.el9_8.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2026:90495.json"}},{"package":{"name":"brotli-devel","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/brotli-devel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.9-10.el9_8.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2026:90495.json"}},{"package":{"name":"libbrotli","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/libbrotli"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.9-10.el9_8.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2026:90495.json"}},{"package":{"name":"python3-brotli","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/python3-brotli"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.9-10.el9_8.1"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2026:90495.json"}}],"schema_version":"1.9.2"}
