Ytterligare information:

Jan Lieskovsky upptäckte ett fel i expat, ett XML-tolkningsbibliotek i C, vid tolkning av vissa UTF-8-sekvenser, som 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+etch2.

För den stabila utgåvan (Lenny) har detta problem rättats i version 2.0.1-4+lenny2.

För uttestningsutgåvan (Squeeze) och den instabila utgåvan (Sid) kommer detta problem att rättas i version 2.0.1-6.

Rättelserna för mipselarkitekturen för den gamla stabila utgåvan är ännu inte inkluderade. De kommer släppas så snart de blir tillgängliga.

Vi rekommenderar att ni uppgraderar era expat-paket.
