DESCRIPTION:
Two vulnerabilities have been reported in Cisco AnyConnect VPN
Client, which can be exploited by malicious people with physical
access to bypass certain security restrictions and by malicious
people to compromise a user's system.

1) An error in the graphical user interface when displayed on the
Windows logon screen can be exploited to perform certain actions with
the privileges of the LocalSystem account.

Successful exploitation of this vulnerability requires the Start
Before Logon (SBL) feature to be enabled.

2) An error in the helper application used for remote deployment of
the client (e.g. "Cisco.AnyConnect.VPNWeb.1" ActiveX control) due to
insufficient authenticity validation of downloaded executables can be
exploited to download and execute an arbitrary program.

Please see the vendor's advisory for a list of affected versions and
platforms.

SOLUTION:
Update to a fixed version (please see the vendor's advisory for
details).

PROVIDED AND/OR DISCOVERED BY:
1) Reported to the vendor by a customer.
2) The vendor credits Elazar Broad via iDefense.
