A vulnerability has been discovered in Microsoft Windows, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to the Windows Progman Group Converter (grpconv.exe) loading libraries (e.g. imm.dll) in an insecure manner. This can be exploited to load arbitrary libraries by tricking a user into e.g. opening a GRP file located on a remote WebDAV or SMB share.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in a fully patched Windows XP SP3 and Windows Server 2003 R2 Enterprise SP2. Other versions may also be affected.
Solution: Do not open untrusted files.
