Re: [nv-l] 512 byte limit on trap variables

It's 512-bytes per varbind and it is
enforced as a result of a CERT advisory which indicated that people might
seek to gain control of your system by sending cunningly-designed traps
which would allow them to crash the trap receiver (trapd) and take over
your box with his (root) authority.
If you get a trap with a varbind which
exceeds 512 bytes, you will see an invalid trap message in trapd.log instead
of that trap, though a trapd.trace with hex dump should show the problem
more clearly.
If you have such a problem, please call
IBM Support so that someone may look at it.

| [nv-l] 512 byte limit on
trap variables |

Is the 512 byte limit for trap variables
still enforced? If yes, would this mean any individual varbind cannot be
more then 512 bytes or the total of all varbinds can not be more then 512
bytes in length? Thanks.
Cheers
