CVE-2024-1544 ECDSA nonce bias caused by truncation

Generating the ECDSA nonce k samples a random number r and then truncates this randomness with a modular reduction mod n where n is the order of the elliptic curve. Meaning k = r mod n. The division used during the reduction estimates a factor qe by dividing the upper two digits a digit having e....

CVE-2024-1544

CVE-2024-1544 describes a bias in the ECDSA nonce generation when k is obtained as r mod n, where a control-flow dependent reduction leaks MSB bias in k. The issue can enable lattice-reduction based reconstruction of k for certain curves (e.g., SECP160R1 with about 15 bits of bias). The connected...

CVE-2024-5288 Safe-error attack on TLS 1.3 Protocol

An issue was discovered in wolfSSL before 5.7.0. A safe-error attack via Rowhammer, namely FAULT+PROBE, leads to ECDSA key disclosure. When WOLFSSLCHECKSIGFAULTS is used in signing operations with private ECC keys, such as in server-side TLS connections, the connection is halted if any fault...

WinSCP < 6.3.3 Key Recovery Attack Vulnerability

The version of WinSCP installed on the remote Windows host is prior to 6.3.3. It is, therefore, affected by a key recovery attack vulnerability. 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 in...

CVE-2024-42460

A flaw was found in the Elliptic NodeJS package where it fails to properly verify the leading bit for the R and S values used in the ECDSA signature. This issue may lead to a scenario where an attacker can modify the signature without the Elliptic library being able to properly reject it, causing...

CVE-2024-42461

A flaw was found in the Elliptic package for Node.js. ECDSA signatures encoded in BER format are improperly validated, allowing leading zeros to be added to the signature without invalidating it, resulting in confidentiality issues. Mitigation Mitigation for this issue is either not available or...

ECDSA Signature Malleability

Elliptic is vulnerable to Signature Malleability. The vulnerability is due to the acceptance of BER-encoded signatures which allows for the manipulation of ECDSA signatures...

ECDSA Signature Malleability

Elliptic is vulnerable to Signature Malleability. The vulnerability is due to the lack of verification for the leading bit of r and s in ECDSA signatures, allowing for signature manipulation...
