Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200705-09
(IPsec-Tools: Denial of Service)

The isakmp_info_recv() function in src/racoon/isakmp_inf.c does not
always check that DELETE (ISAKMP_NPTYPE_D) and NOTIFY (ISAKMP_NPTYPE_N)
packets are encrypted.

Impact :

A remote attacker could send a specially crafted IPsec message to one
of the two peers during the beginning of phase 1, resulting in the
termination of the IPsec exchange.

Workaround :

There is no known workaround at this time.
