CVE-2007-5378 low priority: Ubuntu including 3 source packages (libtk-img, tk8.3, tk8.4), 37 status rows across 13 suites (dapper, edgy, feisty, gutsy, hardy, intrepid, jaunty, karmic, lucid, maverick, natty, oneiric, upstream): not-affected 21, released 12, ignored 3, DNE 1.
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.
