Ubuntu 6.06 LTS / 6.10 / 7.04 / 7.10 : cupsys vulnerabilities (USN-598-1)
Critical Nessus Plugin ID 31785
Synopsis
The remote Ubuntu host is missing one or more security-related patches.
Description
It was discovered that the CUPS administration interface contained a heap- based overflow flaw. A local attacker, and a remote attacker if printer sharing is enabled, could send a malicious request and possibly execute arbitrary code as the non-root user in Ubuntu 6.06 LTS, 6.10, and 7.04. In Ubuntu 7.10, attackers would be isolated by the AppArmor CUPS profile. (CVE-2008-0047)
It was discovered that the hpgl filter in CUPS did not properly validate its input when parsing parameters. If a crafted HP-GL/2 file were printed, an attacker could possibly execute arbitrary code as the non-root user in Ubuntu 6.06 LTS, 6.10, and 7.04. In Ubuntu 7.10, attackers would be isolated by the AppArmor CUPS profile.
(CVE-2008-0053)
It was discovered that CUPS had a flaw in its managing of remote shared printers via IPP. A remote attacker could send a crafted UDP packet and cause a denial of service or possibly execute arbitrary code as the non-root user in Ubuntu 6.06 LTS, 6.10, and 7.04. In Ubuntu 7.10, attackers would be isolated by the AppArmor CUPS profile.
(CVE-2008-0882)
It was discovered that CUPS did not properly perform bounds checking in its GIF decoding routines. If a crafted GIF file were printed, an attacker could possibly execute arbitrary code as the non-root user in Ubuntu 6.06 LTS, 6.10, and 7.04. In Ubuntu 7.10, attackers would be isolated by the AppArmor CUPS profile. (CVE-2008-1373).
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.
Solution
Update the affected packages.
