Vulnerability Assessment Details

RHSA-2004-577: libtiff

Vulnerability Assessment Summary
Check for the version of the libtiff packages

Detailed Explanation for this Vulnerability Assessment


Updated libtiff packages that fix various buffer and integer overflows are
now available.

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.

During a source code audit, Chris Evans discovered a number of integer
overflow bugs that affect libtiff. A possible hacker 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
names CVE-2004-0886 and CVE-2004-0804 to these issues.

Additionally, a number of buffer overflow bugs that affect libtiff have
been found. A possible hacker 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 CVE-2004-0803 to
this issue.

All users are advised to upgrade to these errata packages, which contain
fixes for these issues.
