Description:
Multiple security issues have been reported in OpenBSD ISAKMPd, which potentially can be exploited by malicious people to gain knowledge of sensitive information or delete SAs (Security Associations).
One problem is that some information isn't encrypted in "Quick Mode", which is also the case for the last messages in "Main Mode". This might disclose sensitive information.
Other problems when handling "Delete" messages allow for deletion of IPSec and IKE SAs.
Solution:
The vulnerabilities seem to be addressed in revision 1.62 in the CVS repository.
