CVE-2024-55628

moderate-risk
Published 2025-01-06

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.8, DNS resource name compression can lead to small DNS messages containing very large hostnames which can be costly to decode, and lead to very large DNS log records. While there are limits in place, they were too generous. The issue has been addressed in Suricata 7.0.8.
