Description:
Some vulnerabilities have been reported in Cisco PIX and ASA, which can be exploited by malicious users to gain escalated privileges and by malicious people to cause a DoS (Denial of Service).
1) An unspecified error exists within the enhanced HTTP inspection feature. This can be exploited to crash the device via malformed HTTP requests, but requires that enhanced HTTP inspection is enabled.
2) An unspecified error exists within the SIP packet inspection. This can be exploited to crash the device by sending specially crafted SIP packets, but requires that "inspect" is enabled (it is disabled by default).
3) An unspecified error exists within the TCP-based protocol inspection. This can be exploited to crash the device via malformed packets, but requires that inspection of TCP-based protocols (e.g. FTP or HTTP) is enabled.
4) An unspecified error within the "LOCAL" authentication method can be exploited to gain escalated privileges. Successful exploitation allows gaining privilege level 15 and changing the complete configuration of the device, but requires that the attacker can authenticate to the device and that he is defined in the local database with privilege level 0.
Solution:
Apply updated versions. See the vendor advisory for a patch matrix.
