Description

A security issue has been reported in OpenSSL, which can potentially be exploited by malicious people to bypass certain security restrictions.

The security issue is caused due to an error in the implementation of the Pseudo Random Number Generator (PRNG), where a PRNG key and seed are used that correspond to the last FIPS self-test. This leads to predictable generated random data and may weaken the security of applications relying on the module.

The security issue affects version 1.1.1.

Solution
The vendor has issued two patches that demonstrate fixes for the security issue.
