Further flaws description (from [1]):
=====================================

Security researcher regenrecht reported via TippingPoint's Zero Day Initiative
two instances of code which modifies SVG element lists failed to account for
changes made to the list by user-supplied callbacks before accessing list
elements. If a user-supplied callback deleted such an object, the element-
modifying code could wind up accessing deleted memory and potentially executing
attacker-controlled memory.

regenrecht also reported via TippingPoint's Zero Day Initiative that a XUL
document could force the nsXULCommandDispatcher to remove all command updaters
from the queue, including the one currently in use. This could result in the
execution of deleted memory which an attacker could use to run arbitrary code
on a victim's computer.

Firefox 4 and newer products were not affected by these issues.
