Synopsis
========
Multiple vulnerabilities have been found in OpenSSL, allowing remote
attackers to disclose sensitive information and complete weak
handshakes.

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 < 1.0.2f >= 1.0.2f

Description
===========
Multiple vulnerabilities have been discovered in OpenSSL. Please review
the upstream advisory and CVE identifiers referenced below for details.

Impact
======
A remote attacker could disclose a server's private DH exponent, or
complete SSLv2 handshakes using ciphers that have been disabled on the
server.

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-1.0.2f"
