Details

A flaw was found in dnsmasq. A remote attacker could exploit an out-of-bounds write vulnerability by sending a specially crafted BOOTREPLY (Bootstrap Protocol Reply) packet to a dnsmasq server configured with the --dhcp-split-relay option. This can lead to memory corruption, causing the dnsmasq daemon to crash and resulting in a denial of service (DoS).
