CVE-2011-1945 (GCVE-0-2011-1945)

Vulnerability from cvelistv5 – Published: 2011-05-31 20:00 – Updated: 2024-08-06 22:46
VLAI?
Summary
The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and earlier, when the Elliptic Curve Digital Signature Algorithm (ECDSA) is used for the ECDHE_ECDSA cipher suite, does not properly implement curves over binary fields, which makes it easier for context-dependent attackers to determine private keys via a timing attack and a lattice calculation.
Severity ?
No CVSS data available.
