CVE-2024-47188

Suricata http/byte-ranges: missing hashtable random seed leads to potential DoS

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.

CVE-2024-47187

Suricata datasets: missing hashtable random seed leads to potential DoS

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 datasets having predictable hash table behavior. This can lead to dataset file loading to use excessive time to load, as well as runtime performance issues during traffic handling. This issue has been addressed in 7.0.7. As a workaround, avoid loading datasets from untrusted sources. Avoid dataset rules that track traffic in rules.
