Posted by Team   
Slackware Joost Pol discoverd an off-by-one bug in OpenSSH's channel code that can allow a local attacker to obtain root privileges.

From: Slackware Security Team <>
Subject: [slackware-security] OpenSSH security problem fixed

New openssh packages are available to fix security problems.

Here's the information from the Slackware 8.0 ChangeLog:

Thu Mar  7 12:00:18 PST 2002
patches/packages/openssh.tgz:  Upgraded to openssh-3.1p1.

  This fixes a security problem in the openssh package.  All sites running
  OpenSSH should upgrade immediately.

  All versions of OpenSSH between 2.0 and 3.0.2 contain an off-by-one error
  in the channel code.  OpenSSH 3.1 and later are not affected.  This bug can
  be exploited locally by an authenticated user logging into a vulnerable
  OpenSSH server or by a malicious SSH server attacking a vulnerable OpenSSH
  client.  This bug was discovered by Joost Pol <>

(* Security fix *)

Updated openssh package for Slackware 8.0:

Updated openssh package for Slackware -current:


Here is the md5sum for the package:

Slackware 8.0:
1db0be2661cc1640aaa5797f9eb366db  openssh.tgz

Slackware -current:
d7686a09c398a76b0d0638c8dae615ef  openssh-3.1p1-i386-1.tgz


First, stop sshd:
# /etc/rc.d/rc.sshd stop

Next, upgrade to the new openssh.tgz package:
# upgradepkg openssh.tgz

Finally, restart sshd:
# /etc/rc.d/rc.sshd start

Remember, it's also a good idea to backup configuration files before
upgrading packages.
