Detail

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).

Title: DSA-2879-1 libssh - security update
Description: It was discovered that libssh, a tiny C SSH library, did not reset the state of the PRNG after accepting a connection. A server mode application that forks itself to handle incoming connections could see its children sharing the same PRNG state, resulting in a cryptographic weakness and possibly the recovery of the private key.
