Advisory Text :

Date
December 20, 2005

Vulnerability
The Symantec Antivirus Library provides file format support for virus
analysis. During decompression of RAR files Symantec is vulnerable to
multiple heap overflows allowing attackers complete control of the
system(s) being protected. These vulnerabilities can be exploited remotely
without user interaction in default configurations through common protocols
such as SMTP.

Impact
Successful exploitation of Symantec protected systems allows attackers
unauthorized control of data and related privileges. It also provides
leverage for further network compromise. Symantec implementations are
likely vulnerable in their default configuration. In default configurations
users are likely vulnerable regardless of whether they choose to open or
read the email.

Affected Products
Due to the libraryâ??s modular design and core functionality; it is likely
this vulnerability affects a substantial portion of Symantecâ??s gateway,
server, & client antivirus-enabled product lines on most platforms. In
fact, the scope of this vulnerability is likely similar to the one
described in the following link and also includes more current versions.

http://xforce.iss.net/xforce/alerts/id/187

Further, this library is also licensed to a substantial number of venders
with products/services that are likely affected. A small sample of these
vendors can be found in the following link.

Recommendation
Disable scanning of RAR compressed files until the vulnerable code is
fixed.
