CVE-2019-1549

Name of the Vulnerable Software and Affected Versions OpenSSL versions 1.1.1 through 1.1.1c

Description The issue is related to the random number generator (RNG) in OpenSSL, which was intended to protect against shared RNG state between parent and child processes after a fork() system call. However, this protection was not enabled by default. A mitigation factor is that the output from a high precision timer is mixed into the RNG state, reducing the likelihood of shared state. The problem does not occur if an application explicitly calls OPENSSL init crypto() using OPENSSL INIT ATFORK.

Recommendations For OpenSSL versions 1.1.1 through 1.1.1c, update to version 1.1.1d to resolve the issue. As a temporary workaround, consider explicitly calling OPENSSL init crypto() using OPENSSL INIT ATFORK in applications to prevent the problem.
