Notes

Title of the patch
Security update for dnsmasq
Description of the patch
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 .
