Created attachment 308981 [details]
test xbm file, will crash applications that use affected gdk-pixbuf versions


Attempting to load the attached file in most gtk-based applications, including firefox, will result in a segfault if a vulnerable version of gdk-pixbuf is installed.

Fixed in gdk-pixbuf-2.24.1-r1 (should be stabilized) and gdk-pixbuf-2.26.1 (should not be stabilized for now due to glib-2.32 dependency).

CVE-2012-2370 (
  Multiple integer overflows in the read_bitmap_file_data function in io-xbm.c
  in gdk-pixbuf before 2.26.1 allow remote attackers to cause a denial of
  service (application crash) via a negative (1) height or (2) width in an XBM
  file, which triggers a heap-based buffer overflow.
