==================================================================== Red Hat Security Advisory Synopsis: Important: libtiff security and bug fix update Advisory ID: RHSA-2008:0847-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0847.html Issue date: 2008-08-28 CVE Names: CVE-2008-2327 ==================================================================== 1. Summary: Updated libtiff packages that fix a security issue and a bug are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 3. 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. 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at 5. Bugs fixed (http://bugzilla.redhat.com/): 458674 - CVE-2008-2327 libtiff: use of uninitialized memory in LZW decoder 460120 - [RHEL5] libtiff has unnecessary man pages. 6.
