-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2013:019 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : gnutls Date : March 7, 2013 Affected: Enterprise Server 5.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been found and corrected in gnutls: A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols handled session renegotiation. A man-in-the-middle attacker could use this flaw to prefix arbitrary plain text to a client's session (for example, an HTTPS connection to a website). This could force the server to process an attacker's request as if authenticated using the victim's credentials. This update addresses this flaw by implementing the TLS Renegotiation Indication Extension, as defined in RFC 5746 (CVE-2009-3555). The TLS implementation in GnuTLS before 2.12.23, 3.0.x before 3.0.28, and 3.1.x before 3.1.7 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169 (CVE-2013-1619). The updated packages have been patched to correct these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-3555 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1619 _______________________________________________________________________ Updated Packages: Mandriva Enterprise Server 5: 48dfde02cfa9c869bb97ec71252b8af7 mes5/i586/gnutls-2.4.1-2.8mdvmes5.2.i586.rpm 9f534885a90c121ddb4f911d85462a42 mes5/i586/libgnutls26-2.4.1-2.8mdvmes5.2.i586.rpm 746200c5109707c76a71060672bedfa7 mes5/i586/libgnutls-devel-2.4.1-2.8mdvmes5.2.i586.rpm 8c9bbb918f94a539d82ef057dc201bd2 mes5/SRPMS/gnutls-2.4.1-2.8mdvmes5.2.src.rpm Mandriva Enterprise Server 5/X86_64: dce865b93f4a52aeae1686aed09136f3 mes5/x86_64/gnutls-2.4.1-2.8mdvmes5.2.x86_64.rpm 345540258af6fde7320c7b518c179509 mes5/x86_64/lib64gnutls26-2.4.1-2.8mdvmes5.2.x86_64.rpm b7c9a97fd0f01c52728fbdbc96b3ba55 mes5/x86_64/lib64gnutls-devel-2.4.1-2.8mdvmes5.2.x86_64.rpm 8c9bbb918f94a539d82ef057dc201bd2 mes5/SRPMS/gnutls-2.4.1-2.8mdvmes5.2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
