Slackware alert: 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 <joost@pine.nl>

(* Security fix *)
