Beskrivelse:
Alex Wheeler har rapporteret en sårbarhed i Symantec AntiVirus, som kan udnyttes af ondsindede personer til at kompromittere en brugers system.

Sårbarheden skyldes en ikke-kontrolleret buffer i Dec2Rar.dll ved kopiering af data baseret på længde feltet i sub-block headeren i et RAR arkiv. Dette kan udnyttes til at forårsage et heap-baseret buffer overflow og kan muligvis føre til eksekvering af vilkårlig kode når et ondsindet RAR arkiv scannes.

Sårbarheden er rapporteret i Dec2Rar.dll version 3.2.14.3 og berører potentielt alle Symantec produkter der benytter den berørte DLL fil.
