From 8.0.0 until 8.0.6, the DHCP parser in rust/src/dhcp/dhcp.rs creates stateless transactions without recording their packet direction with AppLayerTxData::for_direction(), so a sensor that observes only one direction cannot mark the unseen direction inspected or free completed transactions. The RDP parser in rust/src/rdp/rdp.rs has the same direction-state defect. The per-flow transaction list can grow without bound and cleanup repeatedly scans it, causing increasing CPU and memory consumption and eventual denial of service. This issue is fixed in version 8.0.6."}], "lastModified": "2026-09-28T18:36:45.227", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"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"}
