DESCRIPTION:
Multiple vulnerabilities have been reported in Cisco Adaptive
Security Appliances (ASA), which can be exploited by malicious people
to bypass certain security restrictions and cause a DoS (Denial of
Service).

For more information:
SA46278

1) An error in the MSN IM inspection feature within the IM inspection
engine can be exploited to cause a crash via specially crafted packets
that transit the appliance.

Successful exploitation requires that the MSN IM inspection is
enabled (disabled by default).

Note: The vulnerabilities only affect the Cisco ASA 5500 Series and
Cisco Catalyst 6500 Series.

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

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

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
