Ytterligare information:

”infamous41md” och Chris Evans upptäckte flera heapbaserade buffertspill i xpdf, en svit för att hantera Portable Document Format (PDF), vilket även ingår i libextractor, ett bibliotek för att hämta godtycklig metadata från filer, vilka kunde användas till överbelastningsattacker genom att krascha programmet eller möjligen till att exekvera godtycklig kod.

Den gamla stabila utgåvan (Woody) innehåller inte paketet libextractor.

För den stabila utgåvan (Sarge) har dessa problem rättats i version 0.4.2-2sarge2.

För den instabila utgåvan (Sid) kommer dessa problem att rättas inom kort.

Vi rekommenderar att ni uppgraderar era libextractor-paket.
