-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : openssh SUMMARY : OpenSSH vulnerability DATE : 2002-03-07 17:44:00 ID : CLA-2002:467 RELEVANT RELEASES : 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0 - ------------------------------------------------------------------------- DESCRIPTION OpenSSH is a very popular and versatile tool that uses encrypted connections between hosts and is commonly used for remote administration. Joost Pol <joostat_private> discovered[1] a off-by-one bug in OpenSSH's channel code that could be used by an attacker with a local account on the victim's machine to obtain root privileges on that machine. Another scenario for this vulnerability is that of a malicious ssh server exploiting a vulnerable ssh client connecting to it. SOLUTION It is recommended that all OpenSSH users upgrade their packages. The sshd service will be automatically restarted after the upgrade if it was already running at that time.
