Description

A vulnerability in Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected system. This vulnerability is due to uncontrolled memory allocation. An attacker could exploit this vulnerability by copying a crafted file to a specific folder on the system.
