The vulnerability is caused by a stale pointer in the WebKit engine when deleting a Ruby tag and its children in a specific order, which could be exploited by remote attackers to compromise a vulnerable system via a specially crafted web page.
There are no specifics in your report, and it seems to suggest www-client/chromium-14.0.835.202 is *not* vulnerable, and we already have a bug for that one. *** This bug has been marked as a duplicate of bug 385649 ***
