Message-Id: <E1VCsU0-00045r-Nr@titan.mandriva.com> Date: Fri, 23 Aug 2013 16:37:00 +0200 From: security@...driva.com To: full-disclosure@...ts.grok.org.uk Subject: [ MDVSA-2013:219 ] libtiff -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ 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). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4231 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4232 http://advisories.mageia.org/MGASA-2013-0258.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 26c946236bf17abb20eaff3f27bc880b mbs1/x86_64/lib64tiff5-4.0.1-3.3.mbs1.x86_64.rpm 6204b5dbe8250246d9be4c9eb3d7b87d mbs1/x86_64/lib64tiff-devel-4.0.1-3.3.mbs1.x86_64.rpm 2dc959358955ced919e655171ca8276a mbs1/x86_64/lib64tiff-static-devel-4.0.1-3.3.mbs1.x86_64.rpm 97ca36de8a29a9c4c9c6f89b6652116d mbs1/x86_64/libtiff-progs-4.0.1-3.3.mbs1.x86_64.rpm d57391c99eb0ac5591fe56d189a22c85 mbs1/SRPMS/libtiff-4.0.1-3.3.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
