Mandriva Linux Security Advisory MDVSA-2014:053
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : libssh
Date : March 13, 2014
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated libssh package fixes security vulnerability:

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).
