Description Vasyl Kaigorodov 2014-05-15 14:22:31 UTC 
It was discovoered [1] that the Mumble client did not properly HTML-escape some external strings before using them in a rich-text (HTML) context.
In some situations, this could be abused to perform a Denial of Service attack (hang and/or resource exhaustion) on a Mumble client by causing it to load external files via the HTML.

A fix for this issue has been released in Mumble 1.2.6.
The fix is also available in the Mumble git repo as:
	e30d7acda6c04b667618ac86f49786cf966a08fb (on the v1.2.6 branch).
