-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:086 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : libssh Date : March 28, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Updated libssh packages fix security vulnerabilities: When using libssh before 0.6.3, a libssh-based server, when accepting a new connection, forks and the child process handles the request. The RAND_bytes() function of openssl doesn't reset its state after the fork, but simply adds the current process id (getpid) to the PRNG state, which is not guaranteed to be unique. The most important consequence is that servers using EC (ECDSA) or DSA certificates may under certain conditions leak their private key (CVE-2014-0017). Double free vulnerability in the ssh_packet_kexinit function in kex.c in libssh 0.5.x and 0.6.x before 0.6.4 allows remote attackers to cause a denial of service via a crafted kexinit packet (CVE-2014-8132). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0017 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-8132 http://advisories.mageia.org/MGASA-2014-0119.html http://advisories.mageia.org/MGASA-2015-0014.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: a08812e6aa98461ceab65992eb628853 mbs2/x86_64/lib64ssh4-0.5.5-2.1.mbs2.x86_64.rpm b647e4b792d2f530e13be40be19d2807 mbs2/x86_64/lib64ssh-devel-0.5.5-2.1.mbs2.x86_64.rpm 97a766a7cdd74f26e6a3b78d50c7afd3 mbs2/SRPMS/libssh-0.5.5-2.1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
