Is X25519 Associative? Sometimes!

X25519 is a simple Elliptic Curve Diffie-Hellman ECDH function: it takes a scalar a fancy name for an integer1 and an elliptic curve point, and it multiplies the elliptic curve point by the scalar. Point additions and multiplications work modulo the order of the point, just like hours on a watch...

CVE-2019-9498

A flaw was found in wpasupplicant. An attack using invalid scalar/element values is possible against the EAP-pwd server since hostapd and wpasupplicant did not validate these values in the received EAP-pwd-Commit messages. When processing an EAP-pwd Commit frame, the peer's scalar and element...

CVE-2020-10932

An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side...

Cross site scripting

SilverStripe through 4.4.x before 4.4.5 and 4.5.x before 4.5.2 allows Reflected XSS on the login form and custom forms. Silverstripe Forms allow malicious HTML or JavaScript to be inserted through non-scalar FormField attributes, which allows performing XSS Cross-Site Scripting on some forms buil...

Name of the Vulnerable Software and Affected Versions: Mbed TLS versions 2.1 through 2.19.1 Arm Mbed Crypto version 2.1 Description: The issue concerns the ECDSA signature implementation in ecdsa.c, which does not reduce the blinded scalar before computing the inverse. This allows a local attacke...

CVE-2019-20399

The CVE-2019-20399 entry concerns a timing vulnerability in Scalar::check_overflow within Parity libsecp256k1-rs (pre-0.3.1). Multiple connected sources (Red Hat, GHSA, OSV, NVD, OSV, Alpine, etc.) describe that this can allow an attacker to leak information via a side-channel attack. The documen...

Timing Attack

elliptic is vulnerable to timing attack. The leakage of bit-length of a scalar during scalar multiplication on an elliptic curve is possible and can lead to the recovery of the private key under specific conditions...

Timing attacks might allow practical recovery of the long-term private key

In elliptic-php versions priot to 1.0.6, Timing attacks might be possible which can result in practical recovery of the long-term private key generated by the library under certain conditions. Leakage of a bit-length of the scalar during scalar multiplication is possible on an elliptic curve whic...
