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

Multiple vulnerabilities have been found in WebkitGTK+, the worst of
which may allow remote attackers to execute arbitrary code.

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

WebKitGTK+ is a full-featured port of the WebKit rendering engine,
suitable for projects requiring any kind of web integration, offers
Webkit=E2=80=99s full functionality and is used on a wide range of systems.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------

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

Multiple vulnerabilities have been discovered in WebkitGTK+. Please
review the references below for details.

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

A remote attacker could execute arbitrary code, cause a Denial of
Service condition, bypass intended memory-read restrictions, conduct a
timing side-channel attack to bypass the Same Origin Policy, obtain
sensitive information, or spoof the address bar.

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

There is no known workaround at this time.

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

All WebKitGTK+ users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose
 ">=3Dnet-libs/webkit-gtk-2.16.6"

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