RedHat Update for libtiff RHSA-2011:0318-01

Solution
Please Install the Updated Packages.
Insight
The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files. A heap-based buffer overflow flaw was found in the way libtiff processed certain TIFF Internet Fax image files, compressed with the CCITT Group 4 compression algorithm. An attacker could use this flaw 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-2011-0192) Red Hat would like to thank Apple Product Security for reporting this issue. All libtiff users should upgrade to these updated packages, which contain a backported patch to resolve this issue. All running applications linked against libtiff must be restarted for this update to take effect.
Affected
libtiff on Red Hat Enterprise Linux (v. 5 server), Red Hat Enterprise Linux AS version 4, Red Hat Enterprise Linux ES version 4, Red Hat Enterprise Linux WS version 4
