| Description: |
The remote host is missing an update to cupsys
announced via advisory USN-539-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04
Ubuntu 7.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Details follow:
Alin Rad Pop discovered that CUPS did not correctly validate buffer
lengths when processing IPP tags. Remote attackers successfully
exploiting this vulnerability would gain access to the non-root CUPS user
in Ubuntu 6.06 LTS, 6.10, and 7.04. In Ubuntu 7.10, attackers would be
isolated by the AppArmor CUPS profile.
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
cupsys 1.2.2-0ubuntu0.6.06.4
Ubuntu 6.10:
cupsys 1.2.4-2ubuntu3.1
Ubuntu 7.04:
cupsys 1.2.8-0ubuntu8.1
Ubuntu 7.10:
cupsys 1.3.2-1ubuntu7.1
In general, a standard system upgrade is sufficient to affect the
necessary changes.
