Vulnerability from variot
A vulnerability in the GZIP decompression engine of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to bypass configured content filters on the device. The vulnerability is due to improper validation of GZIP-formatted files. An attacker could exploit this vulnerability by sending a malicious file inside a crafted GZIP-compressed file. A successful exploit could allow the attacker to bypass configured content filters that would normally drop the email. An attacker can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. This issue is being tracked by Cisco Bug ID CSCvo82840. AsyncOS Software is a set of operating systems running on it
