DESCRIPTION:
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. Other versions may
also be affected.

SOLUTION:
Do not open untrusted files with an application using this library.

PROVIDED AND/OR DISCOVERED BY:
Originally reported in Inkscape by an unknown person.
