CVE-2001-1141 is a vulnerability of currently unknown severity. The Pseudo-Random Number Generator (PRNG) in SSLeay and OpenSSL before 0.9.6b allows attackers to use the output of small PRNG requests to determine the internal state information, which could be used by attackers to predict future pseudo-random numbers.. EPSS estimates a 4.99% chance of exploitation in the next 30 days.
