A flaw was found in Suricata. A heap out-of-bounds read vulnerability exists in the SMTP MIME quoted-printable decoder. A remote attacker can send specially crafted SMTP traffic, causing a quoted-printable escape sequence to be split across traffic chunks. This can lead to a one-byte read past a heap buffer, resulting in a denial of service by crashing 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.
