CVE-2024-47188: Oisf Suricata

High severity, CVSS 7.5. EPSS: 0.3% chance of exploitation in the next 30 days.

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, missing initialization of the random seed for "thash" leads to byte-range tracking having predictable hash table behavior. This can lead to an attacker forcing lots of data into a single hash bucket, leading to severe performance degradation. This issue has been addressed in 7.0.7.

Affected products

• Oisf Suricata: before 7.0.7 (fixed in 7.0.7)
