Synopsis
========

Multiple vulnerabilities have been found in OpenSSL, the worst of which
allows attackers to conduct a time based side-channel attack.

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 < 1.0.2j >= 1.0.2j

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

Multiple vulnerabilities have been discovered in OpenSSL. Please review
the CVE identifiers and the International Association for Cryptologic
Research's (IACR) paper, "Make Sure DSA Signing Exponentiations Really
are Constant-Time" for further details.

Impact
======

Remote attackers could cause a Denial of Service condition or have
other unspecified impacts. Additionally, a time based side-channel
attack may allow a local attacker to recover a private DSA key.

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-1.0.2j"
