Mandriva Linux Security Advisory MDVSA-2013:219
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : libtiff
Date : August 23, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated libtiff packages fix security vulnerabilities:

Pedro Ribeiro discovered a buffer overflow flaw in rgb2ycbcr, a tool to
convert RGB color, greyscale, or bi-level TIFF images to YCbCr images,
and multiple buffer overflow flaws in gif2tiff, a tool to convert GIF
images to TIFF. A remote attacker could provide a specially-crafted
TIFF or GIF file that, when processed by rgb2ycbcr and gif2tiff
respectively, would cause the tool to crash or, potentially, execute
arbitrary code with the privileges of the user running the tool
(CVE-2013-4231).

Pedro Ribeiro discovered a use-after-free flaw in the
t2p_readwrite_pdf_image\(\) function in tiff2pdf, a tool for converting
a TIFF image to a PDF document. A remote attacker could provide a
specially-crafted TIFF file that, when processed by tiff2pdf, would
cause tiff2pdf to crash or, potentially, execute arbitrary code with
the privileges of the user running tiff2pdf (CVE-2013-4232).
