Details

Updated libtiff packages that fix various security issues and a bug are now
available for Red Hat Enterprise Linux 4.

This update has been rated as having important 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.

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.

A buffer overflow flaw was discovered in the tiff2pdf conversion program
distributed with libtiff. An attacker could create a TIFF file containing
UTF-8 characters that would, when converted to PDF format, cause tiff2pdf
to crash, or, possibly, execute arbitrary code. (CVE-2006-2193)

Additionally, these updated packages fix the following bug:

* the libtiff packages included manual pages for the sgi2tiff and tiffsv
commands, which are not included in these packages. These extraneous manual
pages were removed.

All libtiff users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
