Name of the Vulnerable Software and Affected Versions
Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 4110 appliances (affected versions not specified)
Description
The issue is related to incomplete input validation upon receiving ICMP packets, which could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. An attacker could exploit this by sending a high number of crafted ICMP or ICMPv6 packets to an affected device, potentially causing a memory exhaustion condition that may result in an unexpected reload. No manual intervention is needed to recover the device after the reload.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
