Prior to 7.0.17 and 8.0.6, HTTP SWF decompression with the non-default swf-decompression feature and an unsafe decompress-depth can use the configured depth when allocating in src/util-file-decompression.c instead of limiting the allocation to the Flash file's actual data requirement. A crafted SWF response can therefore trigger an integer-related heap buffer overflow and crash Suricata; the default disabled feature and default depth are not affected. This issue is fixed in versions 8.0.6 and 7.0.17."}], "lastModified": "2026-09-28T18:36:20.180", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:oisf:suricata:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "EBABA2A6-27D4-455F-B761-CE55E448863F", "versionEndExcluding": "7.0.17"}, {"criteria": "cpe:2.3:a:oisf:suricata:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "BAC11753-611D-4E10-9F9B-1C21DD2371C4", "versionEndExcluding": "8.0.6", "versionStartIncluding": "8.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
