Description

HashiCorp Vault's implementation of Shamir's secret sharing uses precomputed table lookups, and is vulnerable to cache-timing attacks.

An attacker with access to, and the ability to observe a large number of unseal operations on the host through a side channel may reduce the search space of a brute force effort to recover the Shamir shares.
