AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates
by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.
Stack Corruption DOS
When open / load a corrupt 'crackfile' with bunch of 'AAAAAAAAAAAAAAAAAAAAAAAAAA's... airsnort crashes and stack is corrupted.
Under File / Load "Crack" File... open corrupt crackfile with bunch of 'A' chars then BOOM...
Tested successfully on Linux OS.
