USN-3179-1 openjdk-8 vulnerabilities

Karthik Bhargavan and Gaetan Leurent discovered that the DES and Triple DES ciphers were vulnerable to birthday attacks. A remote attacker could possibly use this flaw to obtain clear text data from long encrypted sessions. This update moves those algorithms to the legacy algorithm set and causes...

OpenJDK: incorrect ECDSA signature extraction from the DER input (Libraries, 8168714)

It was discovered that the Libraries component of OpenJDK accepted ECDSA signatures using non-canonical DER encoding. This could cause a Java application to accept signature in an incorrect format not accepted by other cryptographic tools...

OpenSSL ECDSA P-256 Private Key Acquisition Vulnerability

OpenSSL is an open source capable of implementing the Secure Sockets Layer SSL v2/v3 and Secure Transport Layer TLS v1 protocols developed by the OpenSSL team as a general-purpose cryptographic library that supports a wide range of cryptographic algorithms including symmetric ciphers, hash...

Botan: Multiple vulnerabilities

Background Botan Japanese for peony is a cryptography library written in C++11. Description Multiple vulnerabilities have been discovered in Botan. Please review the CVE identifiers referenced below for details. Impact A remote attacker might obtain ECDSA secret keys via a timing side-channel...

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...
