CVE-2017-8932

A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by...

CVE-2017-8932

CVE-2017-8932 affects the Go standard library’s ScalarMult on the P-256 curve for amd64. The bug causes incorrect results for certain input points, enabling an adaptive attack that progressively extracts the scalar in the ScalarMult operation and can lead to a full key recovery for static ECDH as...

Tenable SecurityCenter OpenSSL 1.0.2 < 1.0.2k Multiple Vulnerabilities (TNS-2017-04)

The Tenable SecurityCenter application installed on the remote host is missing a security patch. It is, therefore, affected by multiple vulnerabilities in the bundled version of OpenSSL : - A carry propagation error exists in the Broadwell-specific Montgomery multiplication procedure when handlin...

CVE-2017-8932

A carry propagation flaw was found in the implementation of the P-256 elliptic curve in golang. An attacker could possibly use this flaw to extract private keys when static ECDH was used...

Design/Logic Flaw

There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is...

ALPINE-CVE-2016-7055

There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is...

CVE-2016-7055

CVE-2016-7055 describes a carry-propagating bug in the Broadwell-specific Montgomery multiplication inside OpenSSL 1.0.2 and 1.1.0 before 1.1.0c. The issue can cause transient authentication and key‑negotiation failures or incorrect public-key results; among EC algorithms, Brainpool P-512 curves ...

Invalid Curve Attack

github.com/dvsekhvalnov/jose2go is vulnerable to invalid curve attacks. These attacks are possible when using key agreement with Elliptic Curve Diffie-Hellman Ephemeral Static ECDH-ES, allowing attackers to recover the private secret key...

MySQL 5.7.x < 5.7.18 Multiple Vulnerabilities (April 2017 CPU) (July 2017 CPU)

The version of MySQL running on the remote host is 5.7.x prior to 5.7.18. It is, therefore, affected by multiple vulnerabilities : - A carry propagation error exists in the OpenSSL component in the Broadwell-specific Montgomery multiplication procedure when handling input lengths divisible by but...

Security Advisory - OpenSSL Montgomery multiplication may produce incorrect results Vulnerability

The Broadwell-specific Montgomery multiplication procedure has a denial of service DoS vulnerability when handling input longer than 256 bits.Only EC algorithms that use Brainpool P-512 curves are affected. An attacker could exploit this vulnerability to cause DoS during ECDH key...

CVE-2016-9121

go-jose before 1.0.4 suffers from an invalid curve attack for the ECDH-ES algorithm. When deriving a shared key using ECDH-ES for an encrypted message, go-jose neglected to check that the received public key on a message is on the same curve as the static private key of the receiver, thus making ...

CVE-2016-9121

CVE-2016-9121 affects square/go-jose prior to version 1.0.4, where ECDH-ES shared-key derivation neglects to verify that the received public key lies on the same elliptic curve as the receiver’s private key. This enables an invalid-curve attack during decryption and is stated across multiple sour...

JSON Libraries Patched Against Invalid Curve Crypto Attack

A number of JSON libraries using the JSON Web Encryption specification JWE to create, sign and encrypt access tokens have been patched against an attack that allows for the recovery of a private key. Researcher Antonio Sanso of Adobe said the go-jose, node-jose, jose2go, Nimbus JOSE+WT and jose4...
