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)");
