The remote host is missing updates announced in
advisory RHSA-2004:577.
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. 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
names CVE-2004-0886 and CVE-2004-0804 to these issues.
Additionally, a number of buffer overflow bugs that affect libtiff have
been found. 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 CVE-2004-0803 to
this issue.
All users are advised to upgrade to these errata packages, which contain
fixes for these issues.
