DESCRIPTION:
A vulnerability has been reported 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.
