Original NVD 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. A successful exploit could allow the attacker to crash the VPN Agent service when the affected application is launched, causing it to be unavailable to all users of the system. To exploit this vulnerability, the attacker must have valid credentials on a multiuser Windows system.
