A flaw was found in Suricata, a network Intrusion Detection System. A local user can craft a detection rule that combines frame inspection without content and a transformed match without content. Loading this specially crafted rule can trigger a heap buffer overflow, leading to a denial of service by crashing the Suricata engine. Network traffic alone cannot exploit this vulnerability. Red Hat Product Security has determined that this vulnerability does not affect any currently supported Red Hat product. This assessment may evolve based on further analysis and discovery. For more information about this vulnerability and the products it affects, please see the linked references. The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
