Description

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.

Affected products

libssh: through 0.6.2; 0.4.7, 0.4.8, 0.5.0, 0.5.0-rc1, 0.5.1, 0.5.2 (+5)
