{"id":"MGASA-2026-0478","summary":"Updated mingw-pcre2 & pcre2 packages fix security vulnerabilities","details":"PCRE2 before 10.48 allows a pcre2_dfa_match out-of-bounds write because\nreuse of a cached workspace block, in a recursive DFA matching\nworkspace, lacks a size check (even though a newly allocated block, for\nthe same purpose, does have a size check). This outcome requires an\nattacker-controlled regular expression, or a recursive pattern in\nconjunction with a small heap limit (this can be set through the API).\n(CVE-2026-86145)\nPCRE2: out-of-bounds write in JIT matching with large stack allocations.\n(CVE-2026-103111)\n","modified":"2026-10-09T17:28:03.923179103Z","published":"2026-10-09T17:00:24Z","upstream":["CVE-2026-103111","CVE-2026-86145"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2026-0478.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=36377"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4WZRH5FLU3A6ZQIPE6WRM7UV7K6S6UHP/"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2026/09/29/2"},{"type":"WEB","url":"https://github.com/PCRE2Project/pcre2/releases/tag/pcre2-10.49"},{"type":"ADVISORY","url":"https://github.com/PCRE2Project/pcre2/security/advisories/GHSA-r9hj-j2rw-4q3m"},{"type":"WEB","url":"https://lists.debian.org/debian-security-announce/2026/msg00443.html"}],"affected":[{"package":{"name":"mingw-pcre2","ecosystem":"Mageia:10","purl":"pkg:rpm/mageia/mingw-pcre2?arch=source&distro=mageia-10"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.49-1.mga10"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2026-0478.json"}},{"package":{"name":"pcre2","ecosystem":"Mageia:10","purl":"pkg:rpm/mageia/pcre2?arch=source&distro=mageia-10"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.49-1.mga10"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2026-0478.json"}}],"schema_version":"1.9.0","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
