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)
CVE-2017-15107: Fixed a vulnerability in DNSSEC implementation.
Processing of wildcard synthesized NSEC records may result improper validation for non-existance (bsc#1076958).
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 .
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
