Subject: CVE Request: heap buffer overflow in gdk-pixbuf


A year ago I found and submitted a vulnerability to the gdk-pixbuf tracker:

It's a heap buffer overflow using a crafted GIF, which is likely 
exploitable in 32 bit systems. Full details are in the link above in the 
bug tracker.

This was patched and the fix was merged 8 months ago as seen here:

The issue is now public, but since no CVE was attributed, it probably is 
not being considered as a problem for downstream users of the package.

As of today, the latest Debian stable package is affected by this 
vulnerability. Using a GNOME file system browser and browsing to that 
folder will cause a crash, as will opening it up in a GNOME image viewer 
and even attempting to load it in Chromium (should have submitted to 
them for a bounty :D).

Hence I'd like to get a CVE to raise awareness for this issue, so that 
downstream users of the package can get patched.

Thanks and regards,
Pedro Ribeiro
