Coco, Alberto SoliAto Testa and Pablo Annetta discovered that Dnsmasq
did not 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.
Update the affected dnsmasq and / or dnsmasq-base packages.
