critical Nessus Plugin ID 38132
Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
It was discovered that CUPS didn't properly handle adding a large number of RSS subscriptions. A local user could exploit this and cause CUPS to crash, leading to a denial of service. This issue only applied to Ubuntu 7.10, 8.04 LTS and 8.10. (CVE-2008-5183)It was discovered that CUPS did not authenticate users when adding and cancelling RSS subscriptions. An unprivileged local user could bypass intended restrictions and add a large number of RSS subscriptions.
This issue only applied to Ubuntu 7.10 and 8.04 LTS. (CVE-2008-5184)
It was discovered that the PNG filter in CUPS did not properly handle certain malformed images. If a user or automated system were tricked into opening a crafted PNG image file, a remote attacker could cause a denial of service or execute arbitrary code with user privileges. In Ubuntu 7.10, 8.04 LTS, and 8.10, attackers would be isolated by the AppArmor CUPS profile. (CVE-2008-5286)
It was discovered that the example pstopdf CUPS filter created log files in an insecure way. Local users could exploit a race condition to create or overwrite files with the privileges of the user invoking the program. This issue only applied to Ubuntu 6.06 LTS, 7.10, and 8.04 LTS. (CVE-2008-5377).
