## Description

Use-after-free vulnerability in the
VisibleSelection::nonBoundaryShadowTreeRootNode function in
core/editing/VisibleSelection.cpp in the DOM implementation in Blink, as
used in Google Chrome before 40.0.2214.111 on Windows, OS X, and Linux and
before 40.0.2214.109 on Android, allows remote attackers to cause a denial
of service or possibly have unspecified other impact via crafted JavaScript
code that triggers improper handling of a shadow-root anchor.
