Synopsis
========

Multiple vulnerabilities have been found in OpenSSL, the worst of which
might allow attackers to access sensitive information.

Background
==========

OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general
purpose cryptography library.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-libs/openssl             < 1.0.2k                  >= 1.0.2k

Description
===========

Multiple vulnerabilities have been discovered in OpenSSL. Please review
the CVE identifiers referenced below for details.

Impact
======

A remote attacker is able to crash applications linked against OpenSSL
or could obtain sensitive private-key information via an attack against
the Diffie-Hellman (DH) ciphersuite.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All OpenSSL users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.2k"
