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).
