Information Disclosure

bouncycastle is vulnerable to information disclosure. The vulnerability exists due to a timing issue within the EC math library that can expose information about the private key when an attacker is able to observe timing information for the generation of multiple deterministic ECDSA signatures...

CVE-2021-29415

The elliptic curve cryptography ECC hardware accelerator, part of the ARM® TrustZone® CryptoCell 310, contained in the NordicSemiconductor nRF52840 through 2021-03-29 has a non-constant time ECDSA implemenation. This allows an adversary to recover the private ECC key used during an ECDSA operatio...
