Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
