Ytterligare information:

Glenn Randers-Pehrson upptäckte ett problem i samband med 16-bitarssamplingar från libpng, ett gränssnitt för att läsa och skriva filer i formatet PNG (Portable Network Graphics). Startvärdet i slingor beräknas felaktigt vilket orsakar ett buffertspill bortom början av radbufferten.

För den nuvarande stabila utgåvan (Woody) har detta problem rättats i version 1.0.12-3.woody.3 av libpng samt i version 1.2.1-1.1.woody.3 av libpng3.

För den gamla stable utgåvan (Potato) har detta problem rättats i version 1.0.5-1.1 av libpng. Några ytterligare libpng-paket finns inte.

För den instabila utgåvan (Sid) har detta problem rättats i version 1.0.12-7 av libpng samt i version 1.2.5-8 av libpng3.

Vi rekommenderar att ni uppgraderar era libpng-paket.
