Description
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. Prior to versions 7.0.13 and 8.0.2, a stack overflow can occur on large HTTP file transfers if the user has increased the HTTP response body limit and enabled the logging of printable http bodies.
