CyberRota Analysis
AI-GeneratedSuricata versions prior to 7.0.16 and 8.0.5 are vulnerable due to a flaw in the IP defragmentation tracker, which fails to ensure that the IP address family of incoming packets matches that of the existing tracker. This vulnerability can be exploited through crafted fragmented IPv4/IPv6 traffic, potentially resulting in a remote denial of service by crashing the Suricata engine. Organizations using Suricata for network security should prioritize upgrading to the patched versions or implementing the recommended workaround to mitigate this risk.

Original NVD Description
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, Suricata's IP defragmentation tracker lookup did not verify that an existing tracker used the same IP address family as the packet being processed. Under crafted fragmented IPv4/IPv6 traffic, an IPv6 fragment could be associated with an IPv4 defragmentation tracker. This can lead to a remote packet-triggered crash and denial of service when Suricata performs the relevant defragmentation. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, if using Suricata as an IDS with AF_PACKET, enabling AF_PACKET's `defrag` option may prevent Suricata from seeing such fragmented packets.
