Details

Drew Yao discovered that the TIFF library did not correctly validate LZW
compressed TIFF images. If a user or automated system were tricked into
processing a malicious image, a remote attacker could execute arbitrary
code or cause an application linked against libtiff to crash, leading
to a denial of service.
