Details

Alexander Gavrun discovered that the TIFF library incorrectly allocated
space for a tile. If a user or automated system were tricked into opening a
specially crafted TIFF image, a remote attacker could execute arbitrary
code with user privileges, or crash the application, leading to a denial of
service. (CVE-2012-1173)

It was discovered that the tiffdump utility incorrectly handled directory
data structures with many directory entries. If a user or automated system
were tricked into opening a specially crafted TIFF image, a remote attacker
could crash the application, leading to a denial of service, or possibly
execute arbitrary code with user privileges. This issue only applied to
Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04.
(CVE-2010-4665)
