3. Description:
The dnsmasq packages contain Dnsmasq, a lightweight DNS (Domain Name
Server) forwarder and DHCP (Dynamic Host Configuration Protocol) server.
Security Fix(es):
* A heap buffer overflow was found in dnsmasq in the code responsible for
building DNS replies. An attacker could send crafted DNS packets to dnsmasq
which would cause it to crash or, potentially, execute arbitrary code.
(CVE-2017-14491)
Red Hat would like to thank Felix Wilhelm (Google Security Team), Fermin J.
Serna (Google Security Team), Gabriel Campana (Google Security Team), Kevin
Hamacher (Google Security Team), and Ron Bowes (Google Security Team) for
