Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP server.
An out-of-bounds read vulnerability has been found in the tcp_request function in Dnsmasq.
A remote attacker could send a specially crafted DNS request, possibly resulting in a Denial of Service condition.
There is no known workaround at this time.
All Dnsmasq users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dns/dnsmasq-2.72-r2"
