CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE   : telnet
SUMMARY   : Remote root vulnerability
DATE      : 2001-08-24 15:43:00
ID        : CLA-2001:413
RELEVANT
RELEASES  : 4.0, 4.0es, 4.1, 4.2, 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0

DESCRIPTION
 The TESO crew reported on Bugtraq a vulnerability affecting the
 telnet server which can be used by remote attackers to obtain root
 privileges. Initially it was thought that the netkit-telnet package,
 used by most linux distributions, was not vulnerable starting with
 version 0.14, but zen-parse showed later on that those versions,
 including the 0.17 one, are also vulnerable.


SOLUTION
 We recommend that all users currently using telnet start using
 openssh instead or some other form of encrypted communication.
 Users who cannot switch to openssh now should upgrade the telnet
 package immediately. Please note that no restart is necessary after
 the upgrade, since telnet is started on demand by inetd.
