Description


Naoto Katsumi has reported a vulnerability in GTK+, which can be exploited by malicious people to compromise an application using the library.

The vulnerability is caused due to the "_gdk_input_wintab_init_check()" (gdk/win32/gdkinput-win32.c) and the "xp_theme_init()" functions (modules/engines/ms-windows/xp_theme.c) loading libraries (wintab32.dll and uxtheme.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 may allow execution of arbitrary code.


Solution:
Update to version 2.24.0.

Provided and/or discovered by:
Naoto Katsumi, LAC Co., Ltd.

According to the advisory, versions prior to 2.21.8 are affected. I had 2.22 installed, but secunia reported it as being vulnerable.

The Secunia recommendation to upgrade to 2.24 appears to be correct.
