Synopsis
========
libTIFF contains buffer overflows that could result in arbitrary code
execution.
Background
==========
libTIFF provides support for reading and manipulating TIFF images.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/tiff lt; 3.8.2-r1 gt;= 3.8.2-r1
Description
===========
A buffer overflow has been found in the t2p_write_pdf_string function
in tiff2pdf, which can been triggered with a TIFF file containing a
DocumentName tag with UTF-8 characters. An additional buffer overflow
has been found in the handling of the parameters in tiffsplit.
Impact
======
A remote attacker could entice a user to load a specially crafted TIFF
file, resulting in the possible execution of arbitrary code.
Workaround
