OpenSSL Concurrent Execution using Shared Resource with Improper Synchronization (Race Condition) Vulnerability - CVE-2010-3864
Multiple race conditions in ssl/t1_lib.c in OpenSSL 0.9.8f through 0.9.8o 1.0.0 and 1.0.0a when multi-threading and internal caching are enabled on a TLS server might allow remote attackers to execute arbitrary code via client data that triggers a heap-based buffer overflow related to (1) the TLS server name extension and (2) elliptic curve cryptography.
