http://secunia.com/advisories/30552/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, DoS

WHERE:
>From remote

OPERATING SYSTEM:
Cisco Adaptive Security Appliance (ASA) 7.x
http://secunia.com/product/6115/
Cisco Adaptive Security Appliance (ASA) 8.x
http://secunia.com/product/16163/

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

1) An unspecified error in the processing of TCP ACK packets can be
exploited to cause a DoS by sending a specially crafted packet to an
affected device.

This vulnerability affects software versions 7.1.x, 7.2.x, and
8.0.x.

2) An unspecified error in the handling of the TLS protocol can be
exploited to cause an affected device to reload by sending a
specially crafted TLS packet to an affected device.

This vulnerability affects software version 8.0.x and 8.1.x.

3) An unspecified error in the Instant Messaging Inspection can be
exploited to cause a DoS.

Successful exploitation requires that Instant Messaging Inspection is
enabled.

This vulnerability affects software versions 7.2.x, 8.0.x, and
8.1.x.

4) An unspecified error can be exploited to cause an affected system
to reload via specially crafted network traffic (e.g. by certain
vulnerability / port scanners) to TCP port 443.

This vulnerability affects software versions 7.2.x and 8.0.x.

5) An unspecified error causes the control-plane access control lists
(ACL) to not work properly, which can be exploited to bypass
configured control-plane ACLs.

This vulnerability affects software versions 8.0.x.

NOTE: Depending on the configuration some of the vulnerabilities are
exploitable via the outside interface (please see the vendor's
advisory for more information).

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

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