Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The TreeScope::adoptIfNeeded function in WebKit/Source/core/dom/TreeScope.cpp in the DOM implementation in Blink, as used in Google Chrome before 50.0.2661.102, does not prevent script execution during node-adoption operations, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.

Mitigation
Install update from vendor's website.

Vulnerable software versions

Opensuse: 13.1

Debian Linux: 8.0 - 13.1
