mdanter/ecc affected by timing vulnerability in cryptographic side-channels

phpecc, as used in all versions of mdanter/ecc, as well as paragonie/ecc before 2.0.1, has a branch-based timing leak in Point addition. This Composer package is also known as phpecc/phpecc on GitHub, previously known as the Matyas Danter ECC library. Paragon Initiative Enterprises hard-forked...

openSUSE 15 Security Update : putty (openSUSE-SU-2024:0111-1)

The remote openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the openSUSE- SU-2024:0111-1 advisory. - In PuTTY 0.68 through 0.80 before 0.81, biased ECDSA nonce generation allows an attacker to recover a user's NIST P-521 secret key via a quick attack i...

Cryptographic side-channels in PHPECC

ECDSA Canonicalization PHPECC is vulnerable to malleable ECDSA signature attacks. Constant-Time Signer When generating a new ECDSA signature, the GMPMath adapter was used. This class wraps the GNU Multiple Precision arithmetic library GMP, which does not aim to provide constant-time implementatio...

Updated putty & filezilla packages fix security vulnerability

The PuTTY client and all related components generate heavily biased ECDSA nonces in the case of NIST P-521. To be more precise, the first 9 bits of each ECDSA nonce are zero. This allows for full secret key recovery in roughly 60 signatures by using state-of-the-art techniques. These signatures c...

Biased ECDSA Nonce Generation

PuTTYis vulnerable to biased ECDSA nonce generation. The vulnerability is due to biased ECDSA nonce generation, allowing an attacker to recover a user's NIST P-521 secret key via a quick attack in approximately 60 signatures. This is particularly significant in scenarios where an adversary can re...
