Details

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)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.10
Ubuntu 7.04
Ubuntu 6.10
Ubuntu 6.06

In general, a standard system upgrade is sufficient to effect the
necessary changes.
