Bowes and Gynvael Coldwind of the Google Security Team discovered
several vulnerabilities in dnsmasq, a small caching DNS proxy and
DHCP/TFTP server, which may result in denial of service, information

For the oldstable distribution (jessie), these problems have been fixed
in version 2.72-3+deb8u2.
