Oracle Linux 3 / 4 / 5 : libtiff (ELSA-2009-1159)

Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2009:1159 :

Updated libtiff packages that fix several security issues are now
available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The libtiff packages contain a library of functions for manipulating
Tagged Image File Format (TIFF) files.

Several integer overflow flaws, leading to heap-based buffer
overflows, were found in various libtiff color space conversion tools.
An attacker could create a specially-crafted TIFF file, which once
opened by an unsuspecting user, would cause the conversion tool to
crash or, potentially, execute arbitrary code with the privileges of
the user running the tool. (CVE-2009-2347)

A buffer underwrite flaw was found in libtiff's Lempel-Ziv-Welch (LZW)
compression algorithm decoder. An attacker could create a
specially-crafted LZW-encoded TIFF file, which once opened by an
unsuspecting user, would cause an application linked with libtiff to
access an out-of-bounds memory location, leading to a denial of
service (application crash). (CVE-2009-2285)

The CVE-2009-2347 flaws were discovered by Tielei Wang from
ICST-ERCIS, Peking University.

All libtiff users should upgrade to these updated packages, which
contain backported patches to correct these issues. After installing
this update, all applications linked with the libtiff library (such as
Konqueror) must be restarted for the update to take effect.
