CVE-2026-71855 Suricata flow: IPv4/IPv6 hash collision can reuse wrong flow state

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.17 and 8.0.6, src/flow-hash.c can treat an IPv4 and IPv6 flow as equal without comparing the IP family when their raw address words, ports, protocol, VLAN, recursion...

CVE-2026-57229

Suricata's SMTP MIME parser (rust/src/mime/smtp.rs) in versions 8.0.0 through 8.0.6 fails to fully reset state when processing Content-Type: message/rfc822 encapsulation. An outer MIME part's filename or Content-Transfer-Encoding state leaks into the inner message, allowing a crafted email to byp...

CVE-2026-63449

Suricata versions 8.0.0 through 8.0.6 are vulnerable to a flaw in the SIP parser (specifically in rust/src/sip/parser.rs). The parser incorrectly uses 16-bit fields to store request and response body lengths. Consequently, a SIP body exceeding 65,536 bytes causes the length to truncate, preventin...
