Título:	Cisco Adaptive Security Appliance Access Control List ICMP Echo Request Code Filtering Vulnerability
Resumen:	A vulnerability in the Cisco Adaptive Security Appliance (ASA) Software;implementation of access control list (ACL) permit and deny filters for ICMP Echo Reply messages could allow;an unauthenticated, remote attacker to bypass ACL configurations for an affected device. ICMP traffic that;should be denied may instead be allowed through an affected device.;;The vulnerability is due to the implementation of ACL-based filters for ICMP Echo Requests and the range of;ICMP Echo Request subtypes. An attacker could exploit this vulnerability by sending ICMP Echo Request traffic;to an affected device. A successful exploit could allow the attacker to bypass ACL configurations for the;device, which could allow traffic that should be denied to instead be allowed through the device.;;Cisco has released software updates that address this vulnerability. There are no workarounds that address;this vulnerability.
