-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- 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.
