Synopsis ========
IPsec-Tools contains a vulnerability that allows a remote attacker to crash the IPsec tunnel.
Background ==========
IPsec-Tools is a port of KAME's implementation of the IPsec utilities. It contains a collection of network monitoring tools, including racoon, ping, and ping6.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-firewall/ipsec-tools < 0.6.7 >= 0.6.7
Description ===========
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.
Resolution ==========
All IPsec-Tools users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-firewall/ipsec-tools-0.6.7"
