Mozilla Foundation Security Advisory 2010-43

Title: Same-origin bypass using canvas context Impact: High Announced: July 20, 2010 Reporter: Vladimir Vukicevic Products: Firefox, Thunderbird

Fixed in: Firefox 3.6.7 Thunderbird 3.1.1 Description

Mozilla developer Vladimir Vukicevic reported that a canvas element can be used to read data from another site, violating the same-origin policy. The read restriction placed on a canvas element which has had cross-origin data rendered into it can be bypassed by retaining a reference to the canvas element's context and deleting the associated canvas node from the DOM.
