CRITICAL:

IMPACT:
DoS, System access

SOFTWARE:

DESCRIPTION:
A vulnerability has been reported in Symantec AntiVirus Scan Engine,
which can be exploited by malicious people to cause a DoS (Denial of
Service) or compromise a vulnerable system.

The vulnerability is caused due to an input validation error in the
web-based Administrative Interface when handling a HTTP request. This
can be exploited to cause a heap-based buffer overflow via a specially
crafted HTTP request that contains a negative value in certain HTTP
headers.

Successful exploitation allows arbitrary code execution with SYSTEM
privileges, but requires the ability to send HTTP requests to port
8004/tcp.

The vulnerability has been reported in the following versions:
* Symantec AntiVirus Scan Engine (version 4.0 and 4.3).
* Symantec AntiVirus Scan Engine for ISA (version 4.0 and 4.3).
* Symantec AntiVirus Scan Engine for Netapp Filer (version 4.0).
* Symantec AntiVirus Scan Engine for Messaging (version 4.3).
* Symantec AntiVirus Scan Engine for Netapp NetCache (version 4.0).
* Symantec AntiVirus Scan Engine for Network Attached Storage
(version 4.3).
* Symantec AntiVirus Scan Engine for Bluecoat (version 4.0).

* Symantec AntiVirus Scan Engine for Microsoft SharePoint (version
4.3).
* Symantec AntiVirus Scan Engine for Clearswift	(version 4.0 and
