The remote host has software installed that is affected by a buffer overflow vulnerability.
The remote host has a version of Cisco AnyConnect 2.x or 3.x prior to 3.1(629). As such, when the VPNAPI COM module calls the ATL framework, certain input data are not properly validated and could allow a buffer overflow. This error could lead to arbitrary code execution.
Upgrade to Cisco AnyConnect Secure Mobility Client 3.0(629) or later.
