properly validate its input when processing TFTP requests for files with
long names. A remote attacker could cause a denial of service or execute
arbitrary code with user privileges. Dnsmasq runs as the 'dnsmasq' user by
default on Ubuntu. (CVE-2009-2957)

Steve Grubb discovered that Dnsmasq could be made to dereference a NULL
pointer when processing certain TFTP requests. A remote attacker could
cause a denial of service by sending a crafted TFTP request.
