[ CQID: WIND00374012 ]
A heap-based buffer overflow flaw was found in the way tiff2pdf, a TIFF image
to a
PDF document conversion tool, of libtiff, a library of functions for
manipulating
TIFF (Tagged Image File Format) image format files, performed write of TIFF
image
content into particular PDF document file, when not properly initialized T2P
context
struct pointer has been provided by tiff2pdf (application requesting the
conversion)
as one of parameters for the routine performing the write. A remote attacker
could
provide a specially-crafted TIFF image format file, that when processed by
tiff2pdf
would lead to tiff2pdf executable crash or, potentially, arbitrary code
execution
with the privileges of the user running the tiff2pdf binary.

Affects libtiff 4.0.2 and earlier.
