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...

MGASA-2024-0140 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...
