CVE-2009-XXXX Content-Type: application/rss+xml being rendered as active content
Previously, we rendered RSS and Atom feeds as XML. Because most other browsers render these documents with dedicated feed previewers, some web sites do not sanitize their feeds for active content, such as
JavaScript. In these cases, an attacker might be able to inject JavaScript into a target web site.

(This issue will be made public once a majority of users are up to date with the fix.)
Severity: Medium. Most web sites are not affected because they do not include untrusted content in RSS or Atom feeds.

Mitigations:
- A victim would need to visit a page under an attacker's control.
- The target web site would need to let the attacker inject JavaScript into an RSS or an Atom feed.
CVE-2009-XXXX Same Origin Policy Bypass via getSVGDocument() method
The getSVGDocument method was lacking an access check, resulting in a cross-origin JavaScript capability leak. A malicious web site operator could use the leaked capability to inject JavaScript into a target web site hosting an SVG document, bypassing the same-origin policy.
