GLSA-200705-09 : IPsec-Tools: Denial of Service

Medium Nessus Plugin ID 25186


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


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.


All IPsec-Tools users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-firewall/ipsec-tools-0.6.7'
