A flaw was found in Suricata. The DHCP and RDP parsers fail to record packet direction for stateless transactions. This allows a network sensor observing only one direction of traffic to accumulate an unbounded list of per-flow transactions. Consequently, this leads to increasing CPU and memory consumption, eventually resulting in a Denial of Service (DoS) for the Suricata engine. 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.
