DESCRIPTION:
A vulnerability has been reported in LibTIFF, which can be exploited
by malicious people to compromise an application using the library.

The vulnerability is caused due to an error within the
"t2p_read_tiff_init()" function (tools/tiff2pdf.c) when handling the
T2P struct pointer and can be exploited to cause a heap-based buffer
overflow via a specially crafted TIFF image.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in version 4.0.2. Other versions may
also be affected.

SOLUTION:
Fixed in the CVS repository.
