IPsec-Tools' racoon is affected by a remote Denial of Service vulnerability.
|Package||net-firewall/ipsec-tools on all architectures|
|Affected versions||< 0.5-r1|
|Unaffected versions||revision >= 0.4-r1, >= 0.5-r1|
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.
Sebastian Krahmer has reported a potential remote Denial of Service vulnerability in the ISAKMP header parsing code of racoon.
An attacker could possibly cause a Denial of Service of racoon using a specially crafted ISAKMP packet.
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-0.4-r1"
