What is CVE-2024-23835?

The Suricata network Intrusion Detection System (IDS), Intrusion Prevention System (IPS), and Network Security Monitoring engine is affected by a vulnerability that arises from excessive memory usage during the parsing of pgsql data. This issue can lead to out-of-memory (OOM) conditions, potentially causing crashes of the engine before version 7.0.3. Users are encouraged to upgrade to version 7.0.3 or implement a workaround by disabling the pgsql application layer parser to mitigate the risk of system failures.

Affected Version(s)

suricata >= 7.0.0, <= 7.0.2
