Cause: Null pointer dereference. There is an unchecked increment of the 'header' variable until a space character is encountered. If a space character is not encountered the pointer is incremented/dereferenced until out of bounds memory is hit. Exploiting this depends on the state of memory at the time so the exploit constantly sends a header with no data as part of the authorization header until a crash occurs. This typically occurs within seconds.

/* xlat table is initialized */
while(*header != ' ')
header++;
