TITLE:
Trend Micro OfficeScan Client Long Pathname Denial of Service

SECUNIA ADVISORY ID:
SA34737

VERIFY ADVISORY:
http://secunia.com/advisories/34737/

DESCRIPTION:
Juan Pablo Lopez Yacubian has discovered a security issue in Trend
Micro OfficeScan Client, which can be exploited by malicious, local
users to cause a DoS (Denial of Service).

The security issue is caused due to an error when scanning
directories having an overly long pathname. This can be exploited to
terminate the NTRtScan.exe process and temporarily disable the
real-time scanning protection by scanning a specially crafted
directory.

The security issue is confirmed in version 8.0 SP1 Patch 1. Other
versions may also be affected.

SOLUTION:
Restrict local access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
Juan Pablo Lopez Yacubian
