OpenSSL random number generator weak security
| openssl-rng-weak-security (42375) |  Low Risk |
Description:
OpenSSL, when running on certain Linux distributions, could provide weaker than expected security. The random number generator creates predictable values. A remote attacker could exploit this vulnerability using brute-force methods to obtain cryptographic key values.
