Prior to versions 8.0.3 and 7.0.14, crafted DCERPC traffic can cause Suricata to expand a buffer w/o limits, leading to memory exhaustion and the process getting killed. While reported for DCERPC over UDP, it is believed that DCERPC over TCP and SMB are also vulnerable. DCERPC/TCP in the default configuration should not be vulnerable as the default stream depth is limited to 1MiB. Versions 8.0.3 and 7.0.14 contain a patch. Some workarounds are available. For DCERPC/UDP, disable the parser. For DCERPC/TCP, the `stream.reassembly.depth` setting will limit the amount of data that can be buffered. For DCERPC/SMB, the `stream.reassembly.depth` can be used as well, but is set to unlimited by default. Imposing a limit here may lead to loss of visibility in SMB."}], "lastModified": "2026-01-30T20:09:24.067", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:oisf:suricata:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5302B0F0-AF2D-4140-BC66-9186EF7E455D", "versionEndExcluding": "7.0.14"}, {"criteria": "cpe:2.3:a:oisf:suricata:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E7DA8362-52A2-4ACC-83F7-CA2E77AE89C6", "versionEndExcluding": "8.0.3", "versionStartIncluding": "8.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
