Name of the Vulnerable Software and Affected Versions Suricata versions prior to 7.0.13 Suricata versions prior to 8.0.2

Description Suricata is a network IDS, IPS and NSM engine. Versions of Suricata prior to 7.0.13 and 8.0.2 are susceptible to a stack overflow that can cause the software to crash when SWF decompression is enabled. A workaround involves disabling SWF decompression in the suricata.yaml file (swf-decompression). If SWF decompression must be enabled, set the decompress-depth to a value less than half of the system's stack size.

Recommendations Update Suricata to version 7.0.13 or later. Update Suricata to version 8.0.2 or later. Disable SWF decompression by setting swf-decompression to false in the suricata.yaml file. If SWF decompression must be enabled, set the decompress-depth to a value less than half of the system's stack size.
