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
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
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.
