Description

Security researcher Mariusz Mlynski reported that it is possible to open a chrome privileged web page through plugin objects through interaction with SVG elements. This could allow for arbitrary code execution.

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.
