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)

All running applications linked against libtiff must be restarted for this
update to take effect.
