 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).
