|Gentoo Linux Security Advisory
Title: IPsec-Tools: Denial of Service (GLSA 200705-09)
Date: May 08, 2007
IPsec-Tools contains a vulnerability that allows a remote attacker to crash
the IPsec tunnel.
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.
Vulnerable: < 0.6.7
Unaffected: >= 0.6.7
Architectures: All supported architectures
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.
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.
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"
