Synopsis
Important: libtiff security update
Type/Severity
Security Advisory: Important
Topic
Updated libtiff packages that fix a security issue are now available for
Red Hat Enterprise Linux 2.1 and 3.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
Description
The libtiff packages contain a library of functions for manipulating Tagged
Image File Format (TIFF) files.
Multiple uses of uninitialized values were discovered in libtiff's
Lempel-Ziv-Welch (LZW) compression algorithm decoder. An attacker could
create a carefully crafted LZW-encoded TIFF file that would cause an
application linked with libtiff to crash or, possibly, execute arbitrary
code. (CVE-2008-2327)
Red Hat would like to thank Drew Yao of the Apple Product Security team for
reporting this issue.
All libtiff users are advised to upgrade to these updated packages, which
contain backported patches to resolve this issue.
