medium Nessus Plugin ID 25186

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.

Solution

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