OpenSSL -- timing vulnerability

The OpenSSL project reports:

Microarchitecture timing vulnerability in ECC scalar multiplication. Severity: Low
OpenSSL ECC scalar multiplication, used in e.g. ECDSA and ECDH, has been shown to be vulnerable to a microarchitecture timing side channel attack. An attacker with sufficient access to mount local timing attacks during ECDSA signature generation could recover the private key.
