Ytterligare information:

Simon Kilvington upptäckte att specialskrivna PNG-bilder kan utlösa ett heapspill i libavcodec, multimediabiblioteket i ffmpeg, vilket kan leda till exekvering av godtycklig kod.

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

För den stabila utgåvan (Sarge) har detta problem rättats i version 0.cvs20050313-2sarge1.

För den instabila utgåvan (Sid) har detta problem rättats i version 0.cvs20050918-5.1.

Vi rekommenderar att ni uppgraderar ert ffmpeg-paket.
