Summary

generated automatically from NVD data

OpenSSL 0.9.6d and earlier, as well as 0.9.7-beta2 and earlier, contain buffer overflows in its SSL2 and SSL3 handling. An oversized client master key in SSL2 or an oversized session ID in SSL3 can trigger the overflow, letting a remote attacker execute arbitrary code. The NVD data also lists Oracle products (Application Server, HTTP Server) and Apple Mac OS X as affected, and rates the flaw 7.5 (HIGH, CVSS v2.0).
