Description

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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
