CVE-2011-1945 describes a timing attack vulnerability in the Elliptic Curve Cryptography (ECC) subsystem of OpenSSL versions 1.0.0d and earlier, specifically when using ECDSA with the ECDHE_ECDSA cipher suite. This flaw, rated with a CVSS score of 2.6 (low severity), allows remote attackers to potentially determine private keys due to improper implementation of curves over binary fields. While the attack complexity is high, successful exploitation could lead to the compromise of sensitive cryptographic keys. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this vulnerability.
