3. Description:

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

libtiff did not properly convert between signed and unsigned integer
values, leading to a buffer overflow. An attacker could use this flaw 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-2012-2088)

Multiple integer overflow flaws, leading to heap-based buffer overflows,
were found in the tiff2pdf tool. An attacker could use these flaws to
create a specially-crafted TIFF file that would cause tiff2pdf to crash or,
possibly, execute arbitrary code. (CVE-2012-2113)

All libtiff users should upgrade to these updated packages, which contain
backported patches 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
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

810551 - CVE-2012-2113 libtiff: integer overflow in tiff2pdf leading to heap-buffer overflow when reading a tiled tiff file
832864 - CVE-2012-2088 libtiff: Type conversion flaw leading to heap-buffer overflow
