_______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2009:191 http://www.mandriva.com/security/ _______________________________________________________________________ Package : OpenEXR Date : August 2, 2009 Affected: Corporate 4.0 _______________________________________________________________________ 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. _______________________________________________________________________ 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: Corporate 4.0: 946b1c4d8a4c50aa6130e76c3d6fff06 corporate/4.0/i586/libOpenEXR2-1.2.2-3.1.20060mlcs4.i586.rpm 7f596e5869c12f454dcbd0341e445624 corporate/4.0/i586/libOpenEXR2-devel-1.2.2-3.1.20060mlcs4.i586.rpm c3932240bc5e30f064a5befba72956f1 corporate/4.0/i586/OpenEXR-1.2.2-3.1.20060mlcs4.i586.rpm 13ad97aee38294f44fb49312b13fd2ad corporate/4.0/SRPMS/OpenEXR-1.2.2-3.1.20060mlcs4.src.rpm Corporate 4.0/X86_64: 2443eed8b8599126300fb61f17b14c8c corporate/4.0/x86_64/lib64OpenEXR2-1.2.2-3.1.20060mlcs4.x86_64.rpm 8c57f91c078821221feaf1bb390d9925 corporate/4.0/x86_64/lib64OpenEXR2-devel-1.2.2-3.1.20060mlcs4.x86_64.rpm d8264dce1156e9c60f58f6765d38d317 corporate/4.0/x86_64/OpenEXR-1.2.2-3.1.20060mlcs4.x86_64.rpm 13ad97aee38294f44fb49312b13fd2ad corporate/4.0/SRPMS/OpenEXR-1.2.2-3.1.20060mlcs4.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
