Moshe Kol and Shlomi Oberman of JSOF discovered several
vulnerabilities in dnsmasq, a small caching DNS proxy and DHCP/TFTP
server. They could result in denial of service, cache poisoning or the
execution of arbitrary code.

For the stable distribution (buster), these problems have been fixed in
version 2.80-1+deb10u1.

We recommend that you upgrade your dnsmasq packages.
