The NIST Elliptic Curves Seeds Bounty Has Been Claimed

We now know how the seeds of the NIST elliptic curves were generated: they’re not the hash of some saucy sentence, but the output of drand48 seeded with the time, which was indeed in 1997–98. John Wood, Henry de Valence, Ava Howell, Zack Voase, Lucy Sweet, Amir Omidi, Paul Crowley, Iain McGinniss...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Arm Mbed TLS before version 2.23.0. A side channel allows the recovery of an ECC private key, which is related to functions such as mbedtlsecpcheckpubpriv, mbedtlspkparsekey, mbedtlspkparsekeyfile, mbedtlsecpmul, and mbedtlsecpmulrestartable...

Astra Linux – Vulnerability in mbedtls

The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS from 2.19.1 onwards does not reduce the blinded scalar before computing the inverse. This allows a local attacker to recover the private key through side-channel attacks...

Astra Linux – Vulnerability in Node-Elliptic

The ECDSA implementation of the Elliptic package generates incorrect signatures if the intermediate value ‘k’ calculated based on step 3.2 of RFC 6979 https://datatracker.ietf.org/doc/html/rfc6979 has leading zeros and is susceptible to cryptanalysis, which can lead to the exposure of the secret...

Astra Linux – Vulnerability in Nettle

A flaw was discovered in Nettle versions prior to 3.7.2. In these versions, several Nettle signature verification functions—GOST DSA, EDDSA, and ECDSA—result in the Elliptic Curve Cryptography point ECC’s multiply function being called with out-of-range scalers. This may lead to incorrect results...
