    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
