NVD Description

Note: Versions mentioned in the description apply only to the upstream dnsmasq-utils package and not the dnsmasq-utils package as distributed by RHEL.

A heap-based out-of-bounds write vulnerability in the DHCPv6 implementation of dnsmasq allows local attackers to execute arbitrary code with root privileges via a crafted DHCPv6 packet.
