Description
Mozilla developers added support in the Network Security Services module for preventing a type of man-in-the-middle attack against TLS using forced renegotiation.
Note that to benefit from the fix, Firefox 3.6 and
Firefox 3.5 users will need to set
their security.ssl.require_safe_negotiation preference to
true. Firefox 3 does not contain the fix for this issue.
