Severity:	normal
Title:	WebKitGTK+: Multiple Vulnerabilities
Date:	10/13/2017
Bugs:	#626142
ID:	201710-14

Synopsis

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

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-libs/webkit-gtk	< 2.16.6	>= 2.16.6	All supported architectures

Description

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

Impact

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

There is no known workaround at this time.

Resolution

All WebKitGTK+ users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-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.
