libtiff security update

CentOS Errata and Security Advisory CESA-2008:0847

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.

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.
