A heap-based buffer overflow in CUPS 1.2.x and later was discovered by regenrecht of VeriSign iDenfense that could allow a remote attacker to execute arbitrary code via a crafted CGI search expression . A validation error in the Hp-GL/2 filter was also discovered . Finally, a vulnerability in how CUPS handled GIF files was found by Tomas Hoger of Red Hat, similar to previous issues corrected in PHP, gd, tk, netpbm, and SDL_image . The updated packages have been patched to correct these issues.
