Descriptions
The RSA and DSA decryption code in Nettle makes it easier for attackers to discover private keys via a cache side channel attack.
El código de descifrado RSA y DSA en Nettle facilita a los atacantes cubrir las claves privadas a través de un ataque de canal secundario de caché.
It was found that nettle's RSA and DSA decryption code was vulnerable to cache-related side channel attacks. An attacker could use this flaw to recover the private key from a co-located virtual-machine instance.
Nettle is a cryptographic library that is designed to fit easily in almost any context: In cryptographic toolkits for object-oriented languages, such as C++, Python, or Pike, in applications like lsh or GnuPG, or even in kernel space. Security Fix: Multiple flaws were found in the way nettle implemented elliptic curve scalar multiplication. These flaws could potentially introduce cryptographic weaknesses into nettle's functionality.
