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)

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
