Beskrivelse:
Der er rapporteret en sårbarhed i CHM Lib (chmlib), som potentielt kan udnyttes af ondsindede personer til at kompromittere en brugers system.

Sårbarheden skyldes en input valideringsfejl i "extract_chmLib" eksempel programmet ved udpakning af filer. Dette gør det muligt at udpakke filer til vilkårlige placeringer uden for den angivne folder ved hjælp af ".." katalog traverseringssekvensen.
