patches/packages/proftpd-1.3.3d-i486-1_slack12.0.tgz
This update fixes an unbounded copy operation in sql_prepare_where() that
could be exploited to execute arbitrary code. However, this only affects
servers that use the sql_mod module (which Slackware does not ship), and
in addition the ability to exploit this depends on an SQL injection bug
that was already fixed in proftpd-1.3.2rc2 (this according to upstream).
So in theory, this fix should only be of academic interest.
But in practice, better safe than sorry.
