DESCRIPTION:
Some vulnerabilities have been reported in Cisco Adaptive Security
Appliance (ASA), which can be exploited by malicious people to cause
a DoS (Denial of Service) and disclose potentially sensitive
information.

1) A packet exhaustion error can be exploited to stop the device from
forwarding traffic.

For more information see vulnerability #1 in:
SA43458

2) An error when handling malformed SCCP messages can be exploited to
cause the device to reload.

For more information see vulnerability #2 in:
SA43458

3) An error when processing RIP updates can be exploited to cause the
device to reload.

Successful exploitation requires that a global media termination
address is configured and RIP and the Cisco Phone Proxy features are
enabled. Configurations where the media termination is tied to an
interface are not vulnerable.

4) An error when the device is configured as local CA server can be
exploited to access certain file systems (e.g. "flash:", "disk0:", or
"disk1:" but not "system:"). This can be exploited to gain access to
e.g. certificates, Cisco software images, or backup device
configurations, which may contain shared secrets or passwords.

SOLUTION:
Apply updated software versions. Please see vendor advisories for
details.

PROVIDED AND/OR DISCOVERED BY:
1-3) Reported by the vendor.
4) Discovered by the vendor when handling a customer support case.
