+--------------------------+
patches/packages/proftpd-1.3.0a-i486-1_slack11.0.tgz:
Upgraded to proftpd-1.3.0a plus an additional security patch. Several
security issues were found in proftpd that could lead to the execution of
arbitrary code by a remote attacker, including one in mod_tls that does
not require the attacker to be authenticated first.

HINT: Getting slow download speeds from ftp.slackware.com?
Give slackware.osuosl.org a try. This is another primary FTP site
for Slackware that can be considerably faster than downloading
from ftp.slackware.com.

Thanks to the friendly folks at the OSU Open Source Lab
(http://osuosl.org) for donating additional FTP and rsync hosting
to the Slackware project! :-)
