The remote Red Hat host is missing one or more security updates.
An update for nettle is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
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(es) :
* Multiple flaws were found in the way nettle implemented elliptic
curve scalar multiplication. These flaws could potentially introduce
cryptographic weaknesses into nettle's functionality. (CVE-2015-8803,
* 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. (CVE-2016-6489)
