CVE-2008-3641

El filtro de lenguaje grafico de Hewlett-Packard (HPGL) en el CUPS en versiones anteriores a v1.3.9 permite a atacantes remotos ejecutar codigo a su elección a traves de codigos manipulados de anchura y color de lapiz que permite la sobreescritura de memoria a su elección.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple CUPS. Authentication is not required to exploit this vulnerability.
The specific flaw exists in the Hewlett-Packard Graphics Language filter. Inadequate bounds checking on the pen width and pen color opcodes result in an arbitrary memory overwrite allowing for the execution of arbitrary code as the "hgltops" process uid.

A buffer overflow in the SGI image format decoding routines used by the CUPS image converting filter imagetops was discovered. An attacker could create malicious SGI image files that could possibly execute arbitrary code if the file was printed. An integer overflow flaw leading to a heap buffer overflow was found in the Text-to-PostScript texttops filter. An attacker could create a malicious text file that could possibly execute arbitrary code if the file was printed. Finally, an insufficient buffer bounds checking flaw was found in the HP-GL/2-to-PostScript hpgltops filter. An attacker could create a malicious HP-GL/2 file that could possibly execute arbitrary code if the file was printed. The updated packages have been patched to prevent this issue; for Mandriva Linux 2009.0 the latest CUPS version (1.3.9) is provided that corrects these issues and also provides other bug fixes.
