Synopsis
========

Multiple vulnerabilities have been found in OpenSSL, the worst of which
could result in Denial of Service or Man-in-the-Middle attacks.

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 < 1.0.1j *>= 0.9.8z_p2
>= 1.0.1j

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

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

Impact
======

A remote attacker may be able to cause a Denial of Service condition,
perform Man-in-the-Middle attacks, obtain sensitive information, or
bypass security restrictions.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All OpenSSL 1.0.1 users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=dev-libs/openssl-1.0.1j”

All OpenSSL 0.9.8 users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=dev-libs/openssl-0.9.8z_p2”

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.
