DHCP: DNSmasq DHCPv6 Stack Buffer Overflow
A stack-based buffer overflow has been reported in the DHCPv6 component of dnsmasq. A remote, unauthenticated attacker can exploit this vulnerability by sending a maliciously crafted packet to the target server. Successful exploitation of this vulnerability could result in execution of arbitrary code on the target server with administrative privileges.
Extended Description
