Synopsis
========

Multiple vulnerabilities in Mesa could result in execution of arbitrary
code or Denial of Service.

Background
==========

Mesa is an OpenGL-like graphic library for Linux.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/mesa < 9.1.4 >= 9.1.4

Synopsis
========

Multiple Information Disclosure vulnerabilities in OpenSSL allow remote
attackers to obtain sensitive information via various vectors.

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 < 1.0.1g >= 1.0.1g

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

Multiple vulnerabilities have been found in OpenSSL:

* OpenSSL incorrectly handles memory in the TLS heartbeat extension,
leading to information disclosure of 64kb per request, possibly
including private keys ("Heartbleed bug", OpenSSL 1.0.1 only,
CVE-2014-0160).
* The Montgomery ladder implementation of OpenSSL improperly handles
swap operations (CVE-2014-0076).

Impact
======

A remote attacker could exploit these issues to disclose information,
including private keys or other sensitive information, or perform
side-channel attacks to obtain ECDSA nonces.

Workaround
==========

Disabling the tls-heartbeat USE flag (enabled by default) provides a
workaround for the CVE-2014-0160 issue.

Resolution
==========

All OpenSSL users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.1g"

Note: All services using OpenSSL to provide TLS connections have to be
restarted for the update to take effect. Utilities like
app-admin/lib_users can aid in identifying programs using OpenSSL.

As private keys may have been compromised using the Heartbleed attack,
it is recommended to regenerate them.
