Synopsis
=======
Multiple Information Disclosure vulnerabilities in OpenSSL allow
attackers to obtain 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             < 1.0.2r                  >= 1.0.2r 

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

Impact
=====
A remote attacker to obtain sensitive information, caused by the
failure to immediately close the TCP connection after the hosts
encounter a zero-length record with valid padding.

A local attacker could run a malicious process next to legitimate
processes using the architecture’s parallel thread running capabilities
to leak encrypted data from the CPU's internal processes.

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-1.0.2r"
