A flaw was found in Suricata, a network Intrusion Detection System (IDS) and Intrusion Prevention System (IPS). The Session Initiation Protocol (SIP) parser incorrectly handles large SIP message bodies. When a SIP message body exceeds 65,536 bytes, the parser truncates its length, preventing the full content from being inspected. This allows malicious content within the uninspected portion of the message to evade detection by the system. 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.
