Mandriva Linux Security Advisory : libssh (MDVSA-2014:053)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

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).
