arbitrary code as the "lp" user if the file is printed. A buffer overflow flaw was discovered in the GIF decoding routines used by CUPS image converting filters "imagetops" and "imagetoraster". An attacker
could create a malicious GIF file that could possibly execute arbitrary
code as the "lp" user if the file was printed.
