Red Hat: Updated libtiff packages fix two security issues

The libtiff packages contain a library of functions for manipulating Tagged Image File Format (TIFF) files. Two integer overflow flaws, leading to heap-based buffer overflows, were found in the way libtiff attempted to allocate space for a tile in a TIFF image file. An attacker could use these flaws to create a specially-crafted TIFF file that, when opened, would cause an application linked against libtiff to crash or, possibly, execute arbitrary code.

Updated packages are available from ftp.redhat.com.

3. Description:

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

Two integer overflow flaws, leading to heap-based buffer overflows, were
found in the way libtiff attempted to allocate space for a tile in a TIFF
image file. An attacker could use these flaws to create a specially-crafted
TIFF file that, when opened, would cause an application linked against
libtiff to crash or, possibly, execute arbitrary code. (CVE-2012-1173)

All libtiff users should upgrade to these updated packages, which contain a
backported patch to resolve these issues. All running applications linked
against libtiff must be restarted for this update to take effect.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
