Debian Security Advisory DSA-075-1 [email protected]

Package : netkit-telnet-ssl
Problem type : remote exploit
Debian-specific: no
The telnet daemon contained in the netkit-telnet-ssl_0.16.3-1 package in
the 'stable' (potato) distribution of Debian GNU/Linux is vulnerable to an
exploitable overflow in its output handling.
The original bug was found by <[email protected]>, and announced to
bugtraq on Jul 18 2001. At that time, netkit-telnet versions after 0.14 were
not believed to be vulnerable.
On Aug 10 2001, zen-parse posted an advisory based on the same problem, for
all netkit-telnet versions below 0.17.
More details can be found on http://www.securityfocus.com/archive/1/203000 .
As Debian uses the 'telnetd' user to run in.telnetd, this is not a remote
root compromise on Debian systems; the 'telnetd' user can be compromised.
We strongly advise you update your netkit-telnet-ssl packages to the versions
listed below.
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
Debian GNU/Linux 2.2 alias potato
- ---------------------------------
Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
