Debian DLA-814-1 : openssl security update

Several vulnerabilities were discovered in OpenSSL : CVE-2016-7056 A local timing attack was discovered against ECDSA P-256. CVE-2016-8610 It was discovered that no limit was imposed on alert packets during an SSL handshake. CVE-2017-3731 Robert Swiecki discovered that the RC4-MD5 cipher when...

Ubuntu 14.04 LTS / 16.04 LTS : OpenSSL vulnerabilities (USN-3181-1)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3181-1 advisory. Guido Vranken discovered that OpenSSL used undefined behaviour when performing pointer arithmetic. A remote attacker could possibly use this...

openssl -- timing attack vulnerability

Cesar Pereida Garcia reports: The signing function in crypto/ecdsa/ecdsaossl.c in certain OpenSSL versions and forks is vulnerable to timing attacks when signing with the standardized elliptic curve P-256 despite featuring constant-time curve operations and modular inversion. A software defect...

CVE-2016-7056

A timing attack flaw was found in OpenSSL 1.0.1u and before that could allow a malicious user with local access to recover ECDSA P-256 private keys...

nettle: secp256 calculation bug

The ecc256modp function in ecc-256.c in Nettle before 3.2 does not properly handle carry propagation and produces incorrect output in its implementation of the P-256 NIST elliptic curve, which allows attackers to have unspecified impact via unknown vectors, a different vulnerability than...

CVE-2015-8805

Summary. The CVE-2015-8805 issue affects the nettle cryptographic library prior to version 3.2. The vulnerability is in the elliptic-curve implementation for P-256: the ecc_256_modq function in ecc-256.c does not properly handle carry propagation, producing incorrect output. This is documented al...

CVE-2015-8803

CVE-2015-8803 affects the nettle library: the ecc_256_modp implementation for P-256 may propagate carries incorrectly in nettle before version 3.2, producing incorrect output and potentially allowing unspecified impact. Multiple Nessus reports and advisories (MiracleLinux AXSA-2016-1108, EulerOS ...
