Original Release Date: December 9, 2008
Last Revised: December 9, 2008
Number: ASA-2008-470
Risk Level: Low
Advisory Version: 1.0
Advisory Status: Interim

1. Overview:

The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX(R) operating systems.

A buffer overflow flaw was discovered in the SGI image format decoding routines used by the CUPS image converting filter "imagetops". An attacker could create a malicious SGI image file that could, possibly, execute arbitrary code as the "lp" user if the file was printed. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3639 to this issue.

An integer overflow flaw leading to a heap buffer overflow was discovered in the Text-to-PostScript "texttops" filter. An attacker could create a malicious text file that could, possibly, execute arbitrary code as the "lp" user if the file was printed. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3640 to this issue.

An insufficient buffer bounds checking flaw was discovered 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 as the "lp" user if the file was printed. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3641 to this issue.
