VERIFY ADVISORY:
http://secunia.com/advisories/31730/

CRITICAL:
Moderately critical

IMPACT:
Exposure of sensitive information, DoS

WHERE:
From remote

OPERATING SYSTEM:
Cisco PIX 7.x
http://secunia.com/product/6102/
Cisco PIX 8.x
http://secunia.com/product/16164/
Cisco Adaptive Security Appliance (ASA) 7.x

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

1) An unspecified error when processing SIP packets can be exploited
to reload an affected device that has SIP inspection enabled.

The vulnerability is reported in Cisco PIX and ASA software versions
prior to 7.0(7)16, 7.1(2)71, 7.2(4)7, 8.0(3)20, and 8.1(1)8.

2) An unspecified error when Cisco PIX and Cisco ASA devices are
configured to terminate client based VPN connections can be exploited
to reload the device.

Successful exploitation requires valid user credentials.

The vulnerability is reported in Cisco PIX and Cisco ASA software
versions prior to 7.2(4)2, 8.0(3)14, and 8.1(1)4. Devices that run
software versions 7.0 and 7.1 are reportedly not affected by this
vulnerability.

3) A memory leak in Cisco ASA devices that are configured to
terminate clientless VPN connections can be exploited to reload the
device via specially crafted SSL or HTTP packets.

The vulnerability is reported in Cisco ASA software version prior to
7.2(4)2, 8.0(3)14, or 8.1(1)4. Cisco ASA devices that run software
versions 7.0 and 7.1 are not affected by this vulnerability.

4) An unspecified error within the URI processing in Cisco ASA
devices that terminate clientless remote access VPN connections can
be exploited to reload the device.

The vulnerability is reported in Cisco ASA software versions prior to
8.0(3)15, and 8.1(1)5. Cisco ASA devices that run software versions
7.0, 7.1, or 7.2 are not affected by this vulnerability.

5) An unspecified error in Cisco ASA devices configured to terminate
clientless VPN connections can be exploited to disclose potentially
sensitive information such as usernames and passwords.

Successful exploitation requires that a user is tricked into e.g.
visiting a malicious web server or reply to an email.

The vulnerability is reported in Cisco ASA devices running software
versions 8.0 or 8.1 with clientless VPNs enabled. Cisco ASA devices
that run software versions 7.0, 7.1, or 7.2 are not affected.

SOLUTION:
Update to fixed versions (please see the vendor's advisory for
details).

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
