CVE reference:	CVE-2006-4071

Description: cyanid-E has discovered a vulnerability in Microsoft Windows, which can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerability is caused due to a signedness error in the GDI Client DLL library (gdi32.dll) when processing WMF files. This can be exploited to crash an application using the vulnerable library (e.g. explorer.exe) by tricking a user into viewing a specially crafted WMF file. The vulnerability has been confirmed on a fully patched Windows XP SP2. Other versions may also be affected. Solution: Grant only trusted users access to affected systems. Open trusted WMF files only. Provided and/or discovered by: cyanid-E Changelog: 2006-08-10: Added CVE reference.
