Hello Kurt, Steve, vendors,

a denial of service flaw was found in the way Ekiga, a Gnome based
SIP/H323 teleconferencing application, processed information from
certain OPAL connections ([certain] UTF-8 strings were not verified
for validity prior showing them). A remote attacker (other party
with a not UTF-8 valid name) could use this flaw to cause ekiga
executable crash.
