-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2010:195 http://www.mandriva.com/security/ _______________________________________________________________________ Package : libesmtp Date : October 4, 2010 Affected: 2008.0, 2009.0, 2009.1, 2010.0, 2010.1, Corporate 4.0, Enterprise Server 5.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been found and corrected in libesmtp: libESMTP, probably 1.0.4 and earlier, does not properly handle a \'\0\' (NUL) character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408 (CVE-2010-1192). The match_component function in smtp-tls.c in libESMTP 1.0.3.r1, and possibly other versions including 1.0.4, treats two strings as equal if one is a substring of the other, which allows remote attackers to spoof trusted certificates via a crafted subjectAltName (CVE-2010-1194). Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more: http://store.mandriva.com/product_info.php?cPath=149&products_id=490 The updated packages have been patched to correct these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-1192 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-1194 _______________________________________________________________________ Updated Packages: Mandriva Linux 2008.0: d5d325c2a9394b23714c60c230146162 2008.0/i586/libesmtp5-1.0.4-1.1mdv2008.0.i586.rpm 01e2b2aee7b00bb2c1c63628750ce61a 2008.0/i586/libesmtp5-devel-1.0.4-1.1mdv2008.0.i586.rpm 66721fe590c7b76c26b7f167d3b8d4a4 2008.0/SRPMS/libesmtp-1.0.4-1.1mdv2008.0.src.rpm Mandriva Linux 2008.0/X86_64: 7f9003c599ceef90b25d7f0582515a66 2008.0/x86_64/lib64esmtp5-1.0.4-1.1mdv2008.0.x86_64.rpm 530085f77adcd0dec9e3fb154b0c8c2b 2008.0/x86_64/lib64esmtp5-devel-1.0.4-1.1mdv2008.0.x86_64.rpm 66721fe590c7b76c26b7f167d3b8d4a4 2008.0/SRPMS/libesmtp-1.0.4-1.1mdv2008.0.src.rpm Mandriva Linux 2009.0: 43e4795d0259c57eefd34d9662b1182d 2009.0/i586/libesmtp5-1.0.4-4.1mdv2009.0.i586.rpm f1436a52a7ffcc8f38b2d6617e8324eb 2009.0/i586/libesmtp-devel-1.0.4-4.1mdv2009.0.i586.rpm 2405545e5e3e9cf3a60b0edbbafc61b9 2009.0/SRPMS/libesmtp-1.0.4-4.1mdv2009.0.src.rpm Mandriva Linux 2009.0/X86_64: 85583d41d8b45be05d893af5756ec8d2 2009.0/x86_64/lib64esmtp5-1.0.4-4.1mdv2009.0.x86_64.rpm 2c9cfdf87cd3d1e91792d7e9d4dbdc80 2009.0/x86_64/lib64esmtp-devel-1.0.4-4.1mdv2009.0.x86_64.rpm 2405545e5e3e9cf3a60b0edbbafc61b9 2009.0/SRPMS/libesmtp-1.0.4-4.1mdv2009.0.src.rpm Mandriva Linux 2009.1: fbbae5b5574e8e014253cb5d1f5cfca0 2009.1/i586/libesmtp5-1.0.4-5.1mdv2009.1.i586.rpm 6e08c2b25ea7200bba7a22e2ba7e2bfa 2009.1/i586/libesmtp-devel-1.0.4-5.1mdv2009.1.i586.rpm f2d40725974760c629e0bb296176f1ec 2009.1/SRPMS/libesmtp-1.0.4-5.1mdv2009.1.src.rpm Mandriva Linux 2009.1/X86_64: ee3ff7a9b146f55eccaaefeb966eb473 2009.1/x86_64/lib64esmtp5-1.0.4-5.1mdv2009.1.x86_64.rpm fd3300fcc6a99b084b5fc5cb69478feb 2009.1/x86_64/lib64esmtp-devel-1.0.4-5.1mdv2009.1.x86_64.rpm f2d40725974760c629e0bb296176f1ec 2009.1/SRPMS/libesmtp-1.0.4-5.1mdv2009.1.src.rpm Mandriva Linux 2010.0: 4e992cfb253ac51c72ff420d2862fe35 2010.0/i586/libesmtp5-1.0.4-6.1mdv2010.0.i586.rpm fdccc3a0c98049bb236eeecd7869e666 2010.0/i586/libesmtp-devel-1.0.4-6.1mdv2010.0.i586.rpm 5047b7270f09adffaf5202df4ec4e2cd 2010.0/SRPMS/libesmtp-1.0.4-6.1mdv2010.0.src.rpm Mandriva Linux 2010.0/X86_64: e3dc2c0ced2c25f3ac5ae63931a7f67e 2010.0/x86_64/lib64esmtp5-1.0.4-6.1mdv2010.0.x86_64.rpm 4e1ac4edd11f17dc1e3607be87984077 2010.0/x86_64/lib64esmtp-devel-1.0.4-6.1mdv2010.0.x86_64.rpm 5047b7270f09adffaf5202df4ec4e2cd 2010.0/SRPMS/libesmtp-1.0.4-6.1mdv2010.0.src.rpm Mandriva Linux 2010.1: 5499b0406f43651b5fffd6b5223c0d38 2010.1/i586/libesmtp5-1.0.4-8.1mdv2010.1.i586.rpm 169b22760527862bf65d074179112ac3 2010.1/i586/libesmtp-devel-1.0.4-8.1mdv2010.1.i586.rpm 06903188f0a5201dd2288cc1126a499f 2010.1/SRPMS/libesmtp-1.0.4-8.1mdv2010.1.src.rpm Mandriva Linux 2010.1/X86_64: da58a753b506123906c752350ee79168 2010.1/x86_64/lib64esmtp5-1.0.4-8.1mdv2010.1.x86_64.rpm b9b453aecbaa9740e5b2aaf0538975e5 2010.1/x86_64/lib64esmtp-devel-1.0.4-8.1mdv2010.1.x86_64.rpm 06903188f0a5201dd2288cc1126a499f 2010.1/SRPMS/libesmtp-1.0.4-8.1mdv2010.1.src.rpm Corporate 4.0: 7b2868bc2a7a58d921126c333c6862b1 corporate/4.0/i586/libesmtp5-1.0.4-0.1.20060mlcs4.i586.rpm febd67c3c2c68d8798c17cadfc3c79a8 corporate/4.0/i586/libesmtp5-devel-1.0.4-0.1.20060mlcs4.i586.rpm f2dbeb8bec24531e717b72608b8d5659 corporate/4.0/SRPMS/libesmtp-1.0.4-0.1.20060mlcs4.src.rpm Corporate 4.0/X86_64: b0f3670dc01c62ea4f100ad41c4d9fc3 corporate/4.0/x86_64/lib64esmtp5-1.0.4-0.1.20060mlcs4.x86_64.rpm 065c29c3aa0a708c11602bf7ef029782 corporate/4.0/x86_64/lib64esmtp5-devel-1.0.4-0.1.20060mlcs4.x86_64.rpm f2dbeb8bec24531e717b72608b8d5659 corporate/4.0/SRPMS/libesmtp-1.0.4-0.1.20060mlcs4.src.rpm Mandriva Enterprise Server 5: 700aaa77ad5f282e2df2049bd7132fe2 mes5/i586/libesmtp5-1.0.4-4.1mdvmes5.1.i586.rpm 71c70f199708b4e5e9a91dae8e2d680d mes5/i586/libesmtp-devel-1.0.4-4.1mdvmes5.1.i586.rpm 102df9e6ed4321d9580911c5806be92f mes5/SRPMS/libesmtp-1.0.4-4.1mdvmes5.1.src.rpm Mandriva Enterprise Server 5/X86_64: 403dbe77fd8e01c679ed8113f31068f6 mes5/x86_64/lib64esmtp5-1.0.4-4.1mdvmes5.1.x86_64.rpm 3a55f65b981f961081dc5087fc9ca365 mes5/x86_64/lib64esmtp-devel-1.0.4-4.1mdvmes5.1.x86_64.rpm 102df9e6ed4321d9580911c5806be92f mes5/SRPMS/libesmtp-1.0.4-4.1mdvmes5.1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
