The remote Cisco ASA device is missing a security patch and may be affected by the following issues :
When configured for transparent firewall mode, a packet buffer exhaustion vulnerability could cause the appliance to stop forwarding traffic. (CVE-2011-0393)
When SCCP inspection is enabled, a malformed SCCP message could cause the appliance to reload.
(CVE-2011-0394)
If both RIP and the Cisco Phone Proxy feature are enabled, the appliance may reload when processing valid RIP updates. (CVE-2011-0395)
When the appliance is configured as a local CA server, unauthorized users can obtain sensitive data without providing authentication. (CVE-2011-0396)
