DESCRIPTION:
André Jerleke has reported a vulnerability in various Symantec
AntiVirus products, which can be exploited by malware to bypass
certain scanning functionality.
The vulnerability is caused due to an error in the Symantec Antivirus
component when processing encoded or archived content. This can be
exploited to crash the decomposer component when parsing a specially
crafted RAR file.
Successful exploitation causes malware inside the RAR file to bypass
the scanning functionality.
This vulnerability primarily poses a risk in environments where virus
scanning only is performed on gateway systems, as the malware still is
detected by the RealTime Virus Scan / Auto-Protect functionality when
extracted on systems running Symantec Antivirus.
Certain Windows builds of the following products are affected:
* Symantec Web Security
* Symantec Mail Security for SMTP
* Symantec AntiVirus Scan Engine
* Symantec SAV/Filter for Domino NT
* Symantec Mail Security for Exchange
* Symantec Norton AntiVirus 2005
* Symantec Norton Internet Security 2005
* Symantec Norton System Works 2005
NOTE: See the vendor advisory for a list of affected and fixed
versions.
SOLUTION:
Updates are available via LiveUpdate and from the Symantec Support
site.
