Package : dnsmasq
CVE ID : CVE-2017-14491 CVE-2017-14492 CVE-2017-14493 CVE-2017-14494
CVE-2017-14495 CVE-2017-14496

Felix Wilhelm, Fermin J. Serna, Gabriel Campana, Kevin Hamacher, Ron
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
leak or the execution of arbitrary code.

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

For the stable distribution (stretch), these problems have been fixed in
version 2.76-5+deb9u1.

We recommend that you upgrade your dnsmasq packages.
