Description Tomas Hoger 2008-07-25 12:36:29 UTC
ipsec-tools upstream released 0.7.1 including a fix for a memory leak in racoon
daemon triggered by the invalid proposals, possibly resulting in a denial of
service once daemon runs out of memory.


Upstream patch:

Comment 2 Tomas Mraz 2008-07-31 08:47:49 UTC
The leaks patched in the mentioned patch can happen only when phase 1 is
completed. That means the attacker would have to be authenticated to be able to
make the leaks happen.

Comment 3 Josh Bressers 2008-08-11 17:05:43 UTC
Any guess on what "some configurations" could mean from the upstream announcement?

Comment 4 Tomas Mraz 2008-08-12 09:12:07 UTC
I am not sure about that - it seems to me that in almost any configuration the responder of the IKE negotiation is vulnerable. But as I said in the comment #2 this problem is in the Phase 2 exchange so that means the attacker has to be already authenticated.

CVE id CVE-2008-3651 was assigned to this issue:

Memory leak in racoon/proposal.c in the racoon daemon in ipsec-tools
before 0.7.1 allows remote authenticated users to cause a denial of
service (memory consumption) via invalid proposals.
