A flaw was found in Suricata, a network Intrusion Detection System. A remote attacker could exploit a NULL dereference vulnerability in the Lua TLS certificate information helper. This vulnerability occurs when a Lua script attempts to retrieve certificate details from TLS (Transport Layer Security) traffic where some certificate fields are missing. By sending specially crafted TLS traffic, an attacker could cause Suricata to crash, leading to a denial of service. 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.
