This update for dnsmasq fixes the following issues :
Security issues fixed:
CVE-2019-14834: Fixed a memory leak which could have allowed to remote attackers to cause denial of service via DHCP response creation (bsc#1154849)

Other issues addressed :
Included linux/sockios.h to get SIOCGSTAMP (bsc#1156543).
Removed cache size limit (bsc#1138743).
bsc#1152539: include config files from /etc/dnsmasq.d/*.conf .
