Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/tk < 8.4.15-r1 >= 8.4.15-r1 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. Impact ====== 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.
