Ytterligare information:

Peter Valchev upptäckte ett fel i expat, ett C-bibliotek för XML-tolkning, vid läsning av vissa UTF-8-sekvenser. Felet kan utnyttjas för att krascha en applikation som använder biblioteket.

För den gamla stabila utgåvan (Etch) har detta problem rättats i version 1.95.8-3.4+etch1.

För den stabila utgåvan (Lenny) har detta problem rättats i version 2.0.1-4+lenny1.

För uttestningsutgåvan (Squeeze) och den instabila utgåvan (Sid) kommer detta problem att rättas inom kort.

Vi rekommenderar att ni uppgraderar era expat-paket.
