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...

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update...

The vulnerability of Cisco IPS’ software allows a malicious individual to obtain a one-time code (nonce) for ECDSA encryption.

The vulnerability exists in the implementation of the Montgomery algorithm in OpenSSL, due to the temporal impermanence of the padding operations. Exploiting this vulnerability allows local users to obtain a one-time code nonce for ECDSA by attacking the cache through external channels using the...

Updated botan packages fix security vulnerabilities

Updated botan packages fix security vulnerabilities: During RSA decryption, how long decoding of PKCS 1 v1.5 padding took was input dependent. If these differences could be measured by an attacker, it could be used to mount a Bleichenbacher million-message attack CVE-2015-7827. ECDSA and DSA...

CVE-2016-2849

CVE-2016-2849 affects Botan: the library did not use a constant-time algorithm for modular inverse during ECDSA signing, enabling timing side-channel leakage that could reveal ECDSA secret keys. Affected are Botan versions before 1.10.13 and 1.11.x before 1.11.29. Impact is a remote attacker pote...
