_______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2009:191-1 http://www.mandriva.com/security/ _______________________________________________________________________ Package : OpenEXR Date : December 8, 2009 Affected: 2008.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been found and corrected in OpenEXR: Multiple integer overflows in OpenEXR 1.2.2 and 1.6.1 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via unspecified vectors that trigger heap-based buffer overflows, related to (1) the Imf::PreviewImage::PreviewImage function and (2) compressor constructors. NOTE: some of these details are obtained from third party information (CVE-2009-1720). The decompression implementation in the Imf::hufUncompress function in OpenEXR 1.2.2 and 1.6.1 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors that trigger a free of an uninitialized pointer (CVE-2009-1721). Buffer overflow in the compression implementation in OpenEXR 1.2.2 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via unspecified vectors (CVE-2009-1722). This update provides fixes for these vulnerabilities. Update: Packages for 2008.0 are being provided due to extended support for Corporate products. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1720 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1721 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1722 _______________________________________________________________________ Updated Packages: Mandriva Linux 2008.0: d871ec8916e58946d88cee51dfb29906 2008.0/i586/libOpenEXR4-1.4.0-3.1mdv2008.0.i586.rpm 950408c16ab4787996f3e4a0363a2f08 2008.0/i586/libOpenEXR-devel-1.4.0-3.1mdv2008.0.i586.rpm 7841e6de8a3992014709b5ef4384e7b1 2008.0/i586/OpenEXR-1.4.0-3.1mdv2008.0.i586.rpm 462c13fc16159a38e14f7c4977ddad01 2008.0/SRPMS/OpenEXR-1.4.0-3.1mdv2008.0.src.rpm Mandriva Linux 2008.0/X86_64: fbbc98d890871fa7ee51606c32c40897 2008.0/x86_64/lib64OpenEXR4-1.4.0-3.1mdv2008.0.x86_64.rpm 6898d32809ffee7f7cb2e960ca9244e1 2008.0/x86_64/lib64OpenEXR-devel-1.4.0-3.1mdv2008.0.x86_64.rpm 6b52dedf34ef41052a472049258677d1 2008.0/x86_64/OpenEXR-1.4.0-3.1mdv2008.0.x86_64.rpm 462c13fc16159a38e14f7c4977ddad01 2008.0/SRPMS/OpenEXR-1.4.0-3.1mdv2008.0.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
