CVE-2014-0017

The RANDbytes 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...

libssh -- PRNG state reuse on forking servers

Aris Adamantiadis reports: When accepting a new connection, the server forks and the child process handles the request. The RANDbytes 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...

CVE-2006-3419

CVE-2006-3419 affects Tor prior to 0.1.1.20. The issue stems from using OpenSSL RAND_pseudo_bytes instead of a cryptographically strong RAND_bytes, and seeding entropy at startup with 160-bit chunks without reseeding. This design makes brute-force guessing attacks more feasible for an attacker. M...
