Synopsis
A buffer overflow vulnerability has been discovered in Tk.

Description
Reinhard Max discovered a boundary error in Tk when processing an interlaced GIF with two frames where the second is smaller than the first one.

A remote attacker could entice a user to open a specially crafted GIF image with a Tk-based software, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
Workaround
There is no known workaround at this time.
