Titel:RedHat Update for libtiff RHSA-2011:0392-01
Zusammenfassung:The remote host is missing an update for the 'libtiff'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'libtiff'
package(s) announced via the referenced advisory.

Vulnerability 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 files encoded with a 4-bit run-length encoding scheme from
ThunderScan. 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-2011-1167)

This update also fixes the following bug:

* The RHSA-2011:0318 libtiff update introduced a regression that prevented
certain TIFF Internet Fax image files, compressed with the CCITT Group 4
compression algorithm, from being read. (BZ#688825)

All libtiff users should upgrade to these updated packages, which contain a
backported patch to resolve these issues. All running applications linked
against libtiff must be restarted for this update to take effect.

Affected Software/OS:
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

Please Install the Updated Packages.
