Synopsis
========

Multiple vulnerabilities have been discovered in GNU Libtasn1, the
worse of which can allow a context-dependent attacker to cause a Denial
of Service condition.

Background
==========

The ASN.1 library used in GNUTLS.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/libtasn1 < 3.6 >= 3.6

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

Multiple vulnerabilities have been discovered in GNU Libtasn1. Please
review the CVE identifiers referenced below for details.

Impact
======

A context-dependent attacker could possibly cause a Denial of Service
condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All GNU Libtasn1 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libtasn1-3.6"

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

Synopsis
========

Multiple vulnerabilities have been discovered in PHP, the worst of
which could lead to remote execution of arbitrary code.

Background
==========

PHP is a widely-used general-purpose scripting language that is
especially suited for Web development and can be embedded into HTML.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/php < 5.5.16 >= 5.5.16
*>= 5.4.32
*>= 5.3.29

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

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

Impact
======

A context-dependent attacker can cause arbitrary code execution, create
a Denial of Service condition, read or write arbitrary files,
impersonate other servers, hijack a web session, or have other
unspecified impact. Additionally, a local attacker could gain escalated
privileges.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All PHP 5.5 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.5.16"

All PHP 5.4 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.4.32"

All PHP 5.3 users should upgrade to the latest version. This release
marks the end of life of the PHP 5.3 series. Future releases of this
series are not planned. All PHP 5.3 users are encouraged to upgrade to
the current stable version of PHP 5.5 or previous stable version of PHP
5.4, which are supported till at least 2016 and 2015 respectively.

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.3.29"
