{"id":"RLSA-2026:90501","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\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.","modified":"2026-10-29T12:30:03.190160903Z","published":"2026-10-29T12:00:52.140894Z","upstream":["CVE-2026-111497"],"database_specific":{"source_advisory":"RHSA-2026:90501","license":"CC-BY-4.0","license_url":"https://creativecommons.org/licenses/by/4.0/"},"references":[{"type":"ADVISORY","url":"https://errata.rockylinux.org/RLSA-2026:90501"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2558973"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:90501"}],"affected":[{"package":{"name":"brotli","ecosystem":"Rocky Linux:8","purl":"pkg:rpm/rocky-linux/brotli?distro=rocky-linux-8&epoch=0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0:1.0.6-5.el8_10"}],"database_specific":{"yum_repository":"BaseOS"}}],"database_specific":{"source":"https://storage.googleapis.com/resf-osv-data/RLSA-2026:90501.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}],"credits":[{"name":"Rocky Enterprise Software Foundation"},{"name":"Red Hat"}]}
