Information Disclosure

nss is vulnerable to information disclosure. An attacker is able to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation when using the EM side-channel. With the partial information of the ECDSA nonce an...

Information Disclosure

mbedtls is vulnerable to information disclosure. The vulnerability exists as the ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key v...

CVE-2020-12401

During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar multiplication was removed, resulting in variable-time execution dependent on secret data. This vulnerability affects Firefox 80 and Firefox for Android 80...

CVE-2020-12401

A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDS...

EulerOS 2.0 SP8 : python-ecdsa (EulerOS-SA-2020-1824)

According to the version of the python-ecdsa packages installed, the EulerOS installation on the remote host is affected by the following vulnerability : - A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without...

Signature Malleability

Overview The Elliptic package before version 6.5.3 for Node.js allows ECDSA signature malleability via variations in encoding, leading '\0' bytes, or integer overflows. This could conceivably have a security-relevant impact if an application relied on a single canonical signature. Recommendation...

Signature Malleabillity in elliptic

The Elliptic package before version 6.5.3 for Node.js allows ECDSA signature malleability via variations in encoding, leading '\0' bytes, or integer overflows. This could conceivably have a security-relevant impact if an application relied on a single canonical signature...

Amazon Linux 2 : openssl11 (ALAS-2020-1456)

The version of openssl11 installed on the remote host is prior to 1.1.1c-15. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1456 advisory. In situations where an attacker receives automated notification of the success or failure of a decryption attempt an...

Medium: openssl11

Issue Overview: In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message tha...
