Symantec Multiple Firewall Remote DNS KERNEL Overflow

Release Date:

Symantec Client Security 1.0, 1.1, 2.0(SCF 7.1)
Symantec Norton AntiSpam 2004

Description:
eEye Digital Security has discovered a critical remote vulnerability
within the Symantec firewall product line. A buffer overflow exists
within a core driver component that handles the processing of DNS
(Domain Name Service) requests and responses. By sending a DNS Resource
Record with an overly long canonical name, a traditional stack-based
buffer overflow is triggered. Successful exploitation of this flaw
yields remote KERNEL access to the system.

With the ability to freely execute code at the Ring 0 privilege level,
there are literally no boundaries for an attacker.

It should also be noted, that due to a separate design flaw in the
firewalls handling of incoming packets, this attack can be successfully
performed with all ports filtered, and all intrusion rules set.
AHHAHAHA Oh shit.
