Insight
It was discovered that a buffer overflow in the GIF image parsing code of Tk, a cross-platform graphical toolkit, could lead to denial of service and potentially the execution of arbitrary code. For the stable distribution (etch), this problem has been fixed in version 8.3.5-6etch2. For the old stable distribution (sarge), this problem has been fixed in version 8.3.5-4sarge1. We recommend that you upgrade your tk8.3 packages.
