A vulnerability has been discovered in Pthreads-win32, which can be exploited by malicious people to compromise an application using the library.
The vulnerability is caused due to the "pthread_win32_process_attach_np()" function in pthreadGC2.dll loading libraries (e.g. quserex.dll) in an insecure manner. This can be exploited to load arbitrary libraries when an application using this library e.g. opens a file located on a remote WebDAV or SMB share.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 2.8.0. Prior versions may also be affected.
Solution: Update to version 2.9.1.
Provided and/or discovered by: Originally reported in Inkscape by an unknown person.
