Description


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

1) An error when receiving certain TCP segments while a connection is being terminated can be exploited to make a device unable to accept new TCP connections.

2) Two errors in the Session Initiation Protocol (SIP) inspection feature can be exploited to trigger an appliance reload.

3) An error in the Skinny Client Control Protocol (SCCP) inspection feature can be exploited to trigger an appliance reload.

5) An error when using the "nailed" option can be exploited to reload an appliance via a specially crafted TCP segment that transits the appliance.

6) An error when parsing Internet Key Exchange (IKE) messages can be exploited to disrupt all IPsec tunnels that terminate on an affected device.
