Description Josh Bressers 2007-04-05 15:08:10 UTC
Apple reported a denial of service flaw in the ipsec-tools racoon.  It is
possible for a remote attacker to invalidate an ipsec tunnel between two
machines.  According to upstream:

Anybody who can:

- guess that A and B have established an IPSec tunnel
- guess some basic informations about phase1 (or who is ready to do
  some quick bruteforce....) 
- send packed to A which appears to come from B

Can invalidate that tunnel at any time.
