Title: OpenSSL: Multiple vulnerabilities
Date: December 07, 2016
Bugs: #581234, #585142, #585276, #591454, #592068, #592074,

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”
