The remote Red Hat host is missing one or more security updates.
Updated libtiff packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 4 and 5.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
The libtiff packages contain a library of functions for manipulating
Tagged Image File Format (TIFF) files.
Multiple integer overflow flaws, leading to a buffer overflow, were
discovered in libtiff. An attacker could use these flaws to create a
specially-crafted TIFF file that, when opened, would cause an
application linked against libtiff to crash or, possibly, execute
arbitrary code. (CVE-2010-1411)
Multiple input validation flaws were discovered in libtiff. An
attacker could use these flaws to create a specially-crafted TIFF file
that, when opened, would cause an application linked against libtiff
to crash. (CVE-2010-2481, CVE-2010-2483, CVE-2010-2595, CVE-2010-2597)
Red Hat would like to thank Apple Product Security for responsibly
