I personally don't have access to the full vendor bulletin, but word is out that Juniper JUNOS routers can be crashed or made to reboot with easily spoofed malformed packets. If you are using Juniper routers, make sure to log in to the Juniper support portal to read their security alert.

Also a lot of other bugs that could be easy to exploit. Suggest everyone with Junipers checks out

or Juniper Technical Assistance Center(JTAC) at, or (888) 314-JTAC / +1 408-745-2121
In summary, JunOS builds built on or after 27th March 2009 have all the fixes - so you may already be patched.
Here are the details:
