Security Linux News for Nov 18, 2000

  • LinuxFocus: xinetd (Nov 18, 2000, 23:22)
    "xinetd - extended Internet services daemon - provides a good security against intrusion and reduces the risks of Deny of Services (DoS) attacks. Like the well known couple (inetd+tcpd), it allows to fix the access rights for a given machine, but it can do much more. In this article we will discover its many features."

  • LinuxSecurity.com: Linux Advisory Watch - November 17th 2000 (Nov 18, 2000, 22:00)
    "This week, advisories were released for named, bind, gnupg, tcsh, ncurses, telnetd, nss_ldap, openssh, cups, modutiles, pine, and imap. The vendors include Caldera, Debian, FreeBSD, Mandrake, Conectiva, Immunix, Trustix, Red Hat, Slackware and SuSE. It is critical that you update all vulnerable packages to reduce the risk of being compromised."

  • TheLinuxGurus.org: Building Linux and OpenBSD Firewalls [Book Review] (Nov 18, 2000, 12:06)
    "All in all a terrific resource for building Linux (or OpenBSD) firewalls. My only problem with the book is that I personally believe that a firewall should be an even more minimal machine than even the authors think. ... If you're looking to set up a firewall using Linux or OpenBSD then this book may fit your needs."

  • Debian Security Advisory: New Debian cron packages released (Nov 18, 2000, 05:29)
    "The version of Vixie Cron shipped with Debian GNU/Linux 2.2 is vulnerable to a local attack."

  • Debian Security Advisory: New version of openssh released (Nov 18, 2000, 05:19)
    The adv.fwd security advisory from OpenBSD reported a problem with openssh - when the connection is established the remote ssh server can force the ssh client to enable agent and X11 forwarding.
