Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

Multiple vulnerabilities have been found in OpenSSL, the worst of which
may lead to a Denial of Service condition.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

OpenSSL is a robust, commercial-grade, and full-featured toolkit for
the Transport Layer Security (TLS) and Secure Sockets Layer (SSL)
protocols.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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

Impact
=3D=3D=3D=3D=3D=3D

A remote attacker could cause a Denial of Service condition, recover a
private key in unlikely circumstances, circumvent security restrictions
to perform unauthorized actions, or gain access to sensitive
information.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There are no known workarounds at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All OpenSSL users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=3Ddev-libs/openssl-1.0.2n”
