Details

Martin Barbella discovered that the thunder (aka ThunderScan) decoder in
the TIFF library incorrectly handled an unexpected BitsPerSample value. 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.
