Openswan Denial of Service

NISCC has reported two Denial of Service issues in Openswan.  The
first involves a specially crafted 3DES packet with an invalid key
length.  The second is not entirely understood at this time.

The Openswan project has relased version 2.4.2 to fix the 3DES issue.


This issue also affects FC3

Please do not use 2.4.2 but go to 2.4.4 directly, as this fixes the second
crasher found by the IPsec proto test suite. It is a DOS as well, but it
requires using PSK + aggressive mode and knowing the PSK (which is vulnerable to
a MITM anyway)

I will be folding back your spec changes again sometime this week.

See  http://lists.openswan.org/pipermail/announce/2005-November/000009.html

We did not incorporate your aggressive mode fixes, however various changes to
aggressive mode code were made. Please check if that solved your Cisco 3000
issues. If you still need to apply your patches, please let us know so we can
properly fix those. thanks.
