3. Description:

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

A heap-based buffer overflow flaw was found in the way libtiff processed
certain TIFF images using the Pixar Log Format encoding. An attacker could
create a specially-crafted TIFF file that, when opened, could cause an
application using libtiff to crash or, possibly, execute arbitrary code
with the privileges of the user running the application. (CVE-2012-4447)

A stack-based buffer overflow flaw was found in the way libtiff handled
DOTRANGE tags. 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-2012-5581)

A heap-based buffer overflow flaw was found in the tiff2pdf tool. An
attacker could use this flaw to create a specially-crafted TIFF file that
would cause tiff2pdf to crash or, possibly, execute arbitrary code.
(CVE-2012-3401)

A missing return value check flaw, leading to a heap-based buffer overflow,
was found in the ppm2tiff tool. An attacker could use this flaw to create a
specially-crafted PPM (Portable Pixel Map) file that would cause ppm2tiff
to crash or, possibly, execute arbitrary code. (CVE-2012-4564)

The CVE-2012-5581, CVE-2012-3401, and CVE-2012-4564 issues were discovered
by Huzaifa Sidhpurwala of the Red Hat Security Response Team.

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
