Debian DSA-3773-1 : 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 wh...

Timing Attacks

OpenSSL is vulnerable to timing attacks. Certain cryptographic functions do not run in constant time, meaning that a malicious user can recover a DSA private key based on the time taken for the operations...

Cache-timing Attack

OpenSSL is vulnerable to a cache-timing attack. The attack exists due to a flaw in signing function of crypto/ecdsa/ecdsaossl.c which sets the BNFLGCONSTTIME flag for nonces instead of taking a secure code path in the BNmodinverse method...

Timing Attack Via Authentication

python-jose is vulnerable to timing attacks. The vulnerability is possible because it has a flaw in verification function which allows a constant time comparison for HMAC keys...

CVE-2016-7037

The verify function in Encryption/Symmetric.php in Malcolm Fell jwt before 1.0.3 does not use a timing-safe function for hash comparison, which allows attackers to spoof signatures via a timing attack...

CVE-2016-7037

The CVE concerns Malcolm Fell jwt (before 1.0.3). The verify function in Encryption/Symmetric.php does not use a timing-safe hash comparison, allowing an attacker to spoof signatures via timing attacks. Impact is signature forgery; remediation is upgrading to version 1.0.3 or later (as per refere...
