Symantec Scan Engine RAR File Vulnerabilities
------------------------------------------------------------------------


SUMMARY


<http://www.symantec.com/enterprise/products/overview.jsp?pcid=1008&pvid=836_1> Symantec Scan Engine is a standalone Anti-Virus Engine that exposes a scanning Application Programming Interface (API) directly to developers who wish to integrate protection into their own custom applications. Two vulnerabilities revolving around handling of RAR files have been discovered in Symantec Scan Engine.

DETAILS

Vulnerable Systems:
* Symantec Scan Engine version 5.1.2

Symantec Scan Engine RAR File Buffer Overflow Vulnerability
Remote exploitation of a stack based buffer overflow vulnerability in
Symantec Scan Engine version 5.1.2 could allow an unauthenticated attacker
to execute arbitrary code with the privileges of the scan engine process.

Symantec Scan Engine listens on TCP port 1344 to accept files for scanning
using the Internet Content Adaptation Protocol (ICAP). If the service is
sent a specially malformed RAR file, a stack-based buffer overflow will
occur.

Analysis:
Exploitation allows remote unauthenticated attackers to execute arbitrary
code with the privileges of the scan engine process. The scan engine can
be configured to run either as a normal user or as root. In order to
exploit this vulnerability, an attacker must be able to cause a malicious
RAR file to be scanned by the Symantec Scan Engine. Normally, no
authentication is required to reach the vulnerable code.

Vendor response:
Symantec has addressed this vulnerability by releasing updates for various
versions of the Symantec Scan Engine. For more information, refer to their
advisory at the following URL:

CVE Information:
<http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0309>
CVE-2008-0309

Disclosure Timeline:

06/14/2007 - Initial vendor response
02/26/2008 - Coordinated public disclosure

Symantec Scan Engine RAR File Denial of Service Vulnerability
Remote exploitation of a Denial of Service vulnerability in Symantec Scan
Engine version 5.1.2 could allow an unauthenticated attacker to create a
denial of service (DoS) condition.

Symantec Scan Engine listens on TCP port 1344 to accept files for scanning
using the Internet Content Adaptation Protocol (ICAP). If the service is
sent a malformed RAR file, the service will consume massive amounts of
memory. This can result in a denial of service condition for the
application and operating system.

Analysis:
Exploitation allows remote unauthenticated attackers to cause the process
to consume excessive amounts memory. In order to exploit this
vulnerability, an attacker must be able to cause a malicious RAR file to
be scanned by the Symantec Scan Engine. Normally, no authentication is
required to reach the vulnerable code.

Vendor response:
Symantec has addressed this vulnerability by releasing updates for various
versions of the Symantec Scan Engine. For more information, refer to their
advisory at the following URL:
