Vulnerability from variot

A vulnerability in the detection engine of Cisco Firepower Threat Defense Software could allow an unauthenticated, remote attacker to cause the unexpected restart of the SNORT detection engine, resulting in a denial of service (DoS) condition. The vulnerability is due to the incomplete error handling of the SSL or TLS packet header during the connection establishment. An attacker could exploit this vulnerability by sending a crafted SSL or TLS packet during the connection handshake. An exploit could allow the attacker to cause the SNORT detection engine to unexpectedly restart, resulting in a partial DoS condition while the detection engine restarts. Versions prior to 6.2.3.4 are affected. Cisco Firepower Threat Defense The software contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Exploiting this issue allows remote attackers to cause excessive memory consumption. This issue is being tracked by Cisco Bug ID CSCvj97647. An input validation vulnerability exists in the detection engine in Cisco FTD
