Re: Memory leakage in proftpd leads to remote DoS

The developers of proftpd have tried to confirm this bug, using scripts to
issue the SIZE command for hundred thousands of iterations, and failed to
verify that it does indeed exist.

Versions of proftpd tested: pre10, rc1, rc2, and CVS.  All failed to show
symptoms of this memory leak.


I've investigated the problem a little bit more and it seems that this
memory leakage really _exist_ but only if proftpd runs in INETD mode.

If proftpd works as standalone daemon it works fine and does not consume
system memory.

Merry Christmas and Happy New Millenium :)
