Título:	RedHat Update for nettle RHSA-2016:2582-02
Resumen:	The remote host is missing an update for the 'nettle'; package(s) announced via the referenced advisory.
Descripción:	Summary: The remote host is missing an update for the 'nettle' package(s) announced via the referenced advisory. Vulnerability Insight: 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, CVE-2015-8804, CVE-2015-8805) * 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) Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section. Affected Software/OS: nettle on Red Hat Enterprise Linux Server (v. 7) Solution: Please Install the Updated Packages. CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
