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...

Mbed TLS -- Side-channel attack on ECC key import and validation

Manuel Pégourié-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 is...

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...

CVE-2020-1026

The CVE-2020-1026 issue affects the MSR JavaScript Cryptography Library’s ECC implementation. It results from multiple bugs in ECC code, enabling an attacker to potentially leak a server’s private ECC key (key leakage attack) or craft an invalid ECDSA signature that passes as valid. The vulnerabi...
