Detail

The RAND_bytes function in libssh before 0.6.3, when forking is enabled, does not properly reset the state of the OpenSSL pseudo-random number generator (PRNG), which causes the state to be shared between children processes and allows local users to obtain sensitive information by leveraging a pid collision.

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.
