Description Mark J. Cox 2005-08-10 14:23:14 UTC
When a user specified IPSEC rule to compile is given, we don't check
the bounds of the direction, leading to overflows of the in-socket
IPSEC rule array.  This could allow a local unprivileged user to cause memory
corruption.

Fixed upstream here on 20050726
