Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2010-3864 impacting openssl openssl. Evaluated with CVSS Base Score of 7.6 (UNKNOWN).

Original NVD Description

Source: NIST NVD
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.
