Fedora 2: FEDORA-2004-334 Critical: LibTiff Integer and Buffer Overflows

The libtiff package contains a library of functions for manipulating

TIFF (Tagged Image File Format) image format files. TIFF is a widely

used file format for bitmapped images. TIFF files usually end in the

.tif extension and they are often quite large.

The libtiff package should be installed if you need to manipulate TIFF

format image files.

During a source code audit, Chris Evans discovered a number of integer overflow bugs that affect libtiff. An attacker who has the ability to trick a user into opening a malicious TIFF file could cause the application linked to libtiff to crash or possibly execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0886 to this issue.
