Beskrivelse:
Der er rapporteret nogle sårbarheder i fsplib, som potentielt kan udnyttes af ondsindede personer til at kompromittere en applikation, der benytter biblioteket.

1) En ikke-kontrolleret buffer under håndteringen af filnavne i fsp_readdir_native() kan udnyttes til at forårsage et stack-baseret buffer overflow, hvis MAXNAMLEN er sat til en værdi større end 256.

2) En ikke-kontrolleret buffer under håndteringen af katalog-poster i fsp_readdir() kan udnyttes til at forårsage et stack-baseret buffer overflow på systemer med en utilstrækkelig størrelse allokeret for "d_name" feltet i en katalog-post.

Succesfuld udnyttelse kan muliggøre eksekvering af vilkårlig kode.

NOTE: Funktionen "fsp_readdir_r()" NULL-terminerer ikke destinations-bufferen korrekt under håndteringen af filnavne, der har en størrelse på MAXNAMLEN tegn.

Løsning:
Opdatér til version 0.9.
