ssl(-mz)telnet with /tmp raise

[martin () UNI-MAINZ DE (Christoph Martin)]

-----BEGIN PGP SIGNED MESSAGE-----


There is a security hole in the versions 0.9.2 and 0.11.1 of
SSL(-MZ)telnet.

All users of ssltelnet should update to the newest version, which is
0.11.2. It is availlable from
ftp://ftp.uni-mainz.de/pub/internet/security/ssl/SSL-MZapps/SSL-MZtelnet-0.11.2.tar.gt
or from it's mirrors.

A new Debian Linux version was also released and will appear soon on
ftp://nonus.debian.org/pub/debian-non-US.

Description of the problem:

telnetd has a debugging function in it which writes to
/tmp/SSL.log. Some calls to this function where not removed in the
release version. If someone would link /tmp/SSL.log to a system file
and then telnet into the machine the system file would be corrupted.
