Overview

Affected versions of this package are vulnerable to Covert Timing Channel in the ECDSA signature computation process, which allows an attacker to recover the private key.

Note: This is only exploitable if the attacker has local access to the signing application or a very fast network connection with low latency, which is required to measure the timing.
