Summary

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. (CVE-2008-3639)
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. (CVE-2008-3640)
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. (CVE-2008-3641)
Red Hat would like to thank regenrecht for reporting these issues.
All CUPS users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
