Description OSIDB Bzimport 2026-02-05 17:02:39 UTC 
Dnsmasq-utils 2.79-1 contains a buffer overflow vulnerability in the dhcp_release utility that allows attackers to cause a denial of service by supplying excessive input. Attackers can trigger a core dump and terminate the dhcp_release process by sending a crafted input string longer than 16 characters.
