Ubuntu 6.06 LTS / 7.04 / 7.10 / 8.04 LTS : cupsys vulnerabilities (USN-656-1)

Critical Nessus Plugin ID 37836

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that the SGI image filter in CUPS did not perform proper bounds checking. If a user or automated system were tricked into opening a crafted SGI image, an attacker could cause a denial of service. (CVE-2008-3639)

It was discovered that the texttops filter in CUPS did not properly validate page metrics. If a user or automated system were tricked into opening a crafted text file, an attacker could cause a denial of service. (CVE-2008-3640)

It was discovered that the HP-GL filter in CUPS did not properly check for invalid pen parameters. If a user or automated system were tricked into opening a crafted HP-GL or HP-GL/2 file, a remote attacker could cause a denial of service or execute arbitrary code with user privileges. In Ubuntu 7.10 and 8.04 LTS, attackers would be isolated by the AppArmor CUPS profile. (CVE-2008-3641)

NOTE: The previous update for CUPS on Ubuntu 6.06 LTS did not have the the fix for CVE-2008-1722 applied. This update includes fixes for the problem. We apologize for the inconvenience.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
