proper bounds checking. If a user or automated system were tricked
into opening a crafted SGI image, an attacker could cause a denial
of service. (CVE-2008-3639)

It was discovered that the texttops filter in CUPS did not properly
validate page metrics. If a user or automated system were tricked into
opening a crafted text file, an attacker could cause a denial of
service. (CVE-2008-3640)

It was discovered that the HP-GL filter in CUPS did not properly check
for invalid pen parameters. If a user or automated system were tricked
into opening a crafted HP-GL or HP-GL/2 file, a remote attacker could
cause a denial of service or execute arbitrary code with user
privileges. In Ubuntu 7.10 and 8.04 LTS, attackers would be isolated by
the AppArmor CUPS profile. (CVE-2008-3641)

NOTE: The previous update for CUPS on Ubuntu 6.06 LTS did not have the
fix for CVE-2008-1722 applied. This update includes fixes for the
problem. We apologize for the inconvenience.");
