Description Jan Lieskovsky 2010-05-27 08:31:53 EDT
Security researcher, known under nickname "MustLive", reported:
  [1] http://www.securityfocus.com/archive/1/511327/100/0/threaded

a deficiency in the way Firefox processed web pages, with embedded
images, whose resource pointed to URL, which redirected to a "mailto:"
URL. If a local user was tricked into visiting of such web page,
it could lead to denial of service (excessive resources consumption
or crash).

Official statement from Red Hat Security
Response Team, regarding this deficiency:

Red Hat Security Response Team does not consider a user assisted
denial of service (and potential crash) of end user application,
such a Firefox, to be a security issue.
