Summary
generated automatically from NVD dataThe Pseudo-Random Number Generator (PRNG) in SSLeay and OpenSSL versions before 0.9.6b has a weakness in how it handles small output requests. An attacker who observes the output of such requests can derive the PRNG's internal state, and could then predict future pseudo-random numbers, undermining the secrecy of values that depend on them. The flaw is network-exploitable with low complexity and no authentication, and it is rated 5.0 (MEDIUM) under CVSS v2.0 with a partial confidentiality impact.
NVD description
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.
