In versions prior to 6.0.0, 5.0.4, 4.0.7 and 3.0.14, when processing an op_slice network packet, the server passes an unprepared structure containing a null pointer to the SDL_info() function, resulting in a null pointer dereference and server crash. An unauthenticated attacker can trigger this by sending a crafted packet to the server port. This issue has been fixed in versions 6.0.0, 5.0.4, 4.0.7 and 3.0.14."}], "lastModified": "2026-04-24T19:54:47.800", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:firebirdsql:firebird:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "53D811A2-F880-46E9-9F7F-1CE3AC487F67", "versionEndExcluding": "3.0.14"}, {"criteria": "cpe:2.3:a:firebirdsql:firebird:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "A4BC24D2-FBF7-4308-9914-6079DBDF88FA", "versionEndExcluding": "4.0.7", "versionStartIncluding": "4.0.0"}, {"criteria": "cpe:2.3:a:firebirdsql:firebird:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "938978A3-90BE-4223-BDFC-5310A7C78D9B", "versionEndExcluding": "5.0.4", "versionStartIncluding": "5.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
