CONECTIVA LINUX SECURITY ANNOUNCEMENT
PACKAGE : proftpd
SUMMARY : Denial of Service
DATE : 2001-02-08 19:17:00
ID : CLA-2001:380
RELEVANT
RELEASES : 4.0, 4.0es, 4.1, 4.2, 5.0, prg gráficos, ecommerce, 5.1, 6.0
DESCRIPTION
"proftpd" is a very popular ftp server. Wojciech Purczynski
reported two memory leak problems that could be used in a DoS
attack:
1) A memoy leak will happen everytime a SIZE command is given,
provided that the scoreboard file is not writable. The default
installation is *not* vulnerable to this problem;
2) A similar problem existed with the USER command. Every USER
command would cause the server to use more memory.
Additionally, Przemyslaw Frasunek reported some format string
vulnerabilities which have been fixed.
SOLUTION
It is recommended that all ProFTPd users upgrade to the latest
packages.
ADDITIONAL INSTRUCTIONS
Users of Conectiva Linux version 6.0 or higher may use apt to
perform upgrades:
- add the following line to /etc/apt/sources.list if it is not
there yet (you may also use linuxconf to do this):
