DESCRIPTION:
Some vulnerabilities have been reported in Cisco ASA (Adaptive
Security Appliance) 5500 Series, which can be exploited by malicious
people to cause a DoS (Denial of Service).

1) Three errors exist in the SunRPC inspection engine while
processing certain SunRPC messages. This can be exploited to reload a
device via specially crafted UDP SunRPC packets that transit the
appliance.

2) Three errors exist in the processing of certain TLS packets and
can be exploited to reload the device by sending a series of
specially crafted TLS packets.

Successful exploitation of this vulnerability requires that the
device is configured for SSL VPN, TLS Proxy for Encrypted Voice
Inspection, or configured to accept ASDM management connections.

3) An error in the Session Initiation Protocol (SIP) inspection
feature can be exploited to trigger an appliance reload via a
specially crafted SIP packet that transits the appliance via TCP or
UDP port 5060.

4) An error when parsing Internet Key Exchange (IKE) messages can be
exploited to trigger an appliance reload via specially crafted
packets sent to UDP ports  500 or 4500.

Successful exploitation of this vulnerability requires that the
device is configured for IPsec remote access or site-to-site VPNs

SOLUTION:
Update to a fixed version. Please see the vendor's advisory for
detailed patch information.
