CVE-2020-13822

CVE-2020-13822 concerns the Elliptic package for Node.js (notably versions around 6.5.2) and describes ECDSA signature malleability caused by variations in encoding, leading to spurious or non-canonical signatures (e.g., leading '\0' bytes) and potential security impact if a single canonical sign...

CVE-2020-12607

An issue was discovered in fastecdsa before 2.1.2. When using the NIST P-256 curve in the ECDSA implementation, the point at infinity is mishandled. This means that for an extreme value in k and s^-1, the signature verification fails even if the signature is correct. This behavior is not solely a...

CVE-2020-12607

CVE-2020-12607 affects the fastecdsa library prior to 2.1.2, where using the NIST P-256 curve in the ECDSA implementation mishandles the point at infinity during signature verification. This can cause verification to fail for an otherwise valid signature when extreme values occur for k and s^-1, ...

USN-4376-1: OpenSSL vulnerabilities

Cesar Pereida García, Sohaib ul Hassan, Nicola Tuveri, Iaroslav Gridin, Alejandro Cabrera Aldaya, and Billy Brumley discovered that OpenSSL incorrectly handled ECDSA signatures. An attacker could possibly use this issue to perform a timing side-channel attack and recover private ECDSA keys...

openssl: side-channel weak encryption vulnerability

Normally in OpenSSL EC groups always have a co-factor present and this is used in side channel resistant code paths. However, in some cases, it is possible to construct a group using explicit parameters instead of using a named curve. In those cases it is possible that such a group does not have...
