FreeBSD : Mbed TLS -- Side-channel attack on ECC key import and validation (c685edd9-c045-11ea-8898-001cc0382b2f)
Manuel Pegourie-Gonnard reports : The scalar multiplication function in Mbed TLS accepts a random number generator RNG as an optional argument and, if provided, uses it to protect against some attacks. It is the caller's responsibility to provide a RNG if protection against side-channel attacks i...
Microsoft Edge (Chromium) < 79.0.309.68 Multiple Vulnerabilities
The version of Microsoft Edge Chromium installed on the remote Windows host is prior to 79.0.309.68. It is, therefore, affected by multiple vulnerabilities: - A spoofing vulnerability exists in the Windows CryptAPI due to how it validates Elliptic Curve Cryptography ECC certificates. An...

CVE-2020-11735
The CVE-2020-11735 issue affects wolfSSL’s ECC implementation (ecc.c) in versions prior to 4.4.0, where private-key operations do not use a constant-time modular inverse when mapping to affine coordinates, causing a projective coordinates leak. This is treated as a timing-related vulnerability af...
