What is CVE-2024-32663?

A memory management vulnerability exists in Suricata, a prominent network Intrusion Detection System, Intrusion Prevention System, and Network Security Monitoring engine. This flaw allows a limited amount of HTTP/2 traffic to potentially cause Suricata to consume an excessive amount of memory, leading to performance degradation. The issue has been rectified in Suricata versions 7.0.5 and 6.0.19. As a temporary workaround, users can disable the HTTP/2 parser or adjust the configuration by reducing the default value of app-layer.protocols.http2.max-table-size, which is set to 65536.
