CVE-2007-5378 medium priority: Debian including 1 source packages (libtk-img), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
Buffer overflow in the FileReadGIF function in tkImgGIF.c for Tk Toolkit 8.4.12 and earlier, and 8.3.5 and earlier, allows user-assisted attackers to cause a denial of service (segmentation fault) via an animated GIF in which the first subimage is smaller than a subsequent subimage, which triggers the overflow in the ReadImage function, a different vulnerability than CVE-2007-5137.
