The FC client in IBM's AIX contains a buffer overflow that may cause a core dump in the client.


The IBM AIX FC client allows a buffer overflow of a few bytes in the client process, which could cause intermittent core dumps during session setup. Overflowing the buffer is difficult or impossible without local, privileged access to the client.


Exploitation of this vulnerability causes the FC client to crash.
