A vulnerability has been discovered in TortoiseSVN, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to the application bundling a vulnerable version of mfc90u.dll, which loads libraries (e.g. dwmapi.dll) in an insecure manner. This can be exploited to load arbitrary libraries by tricking a user into e.g. opening a file associated with e.g. TortoiseProc or TortoiseMerge located on a remote WebDAV or SMB share.
Successful exploitation allows execution of arbitrary code, but requires that files are opened in e.g. TortoiseProc or TortoiseMerge (by default no file types are associated with the applications).
The vulnerability is confirmed in version 1.6.10. Other versions may also be affected.
Solution: Do not associate files with or open untrusted files in TortoiseProc or TortoiseMerge.
