Red Hat, Inc. Security Advisory

Synopsis: new initscripts packages available (/tmp race)
Advisory ID: RHSA-1999:052-01
Issue date: 1999-11-08
Updated on: 1999-11-08
Keywords: lang.csh resolv.conf CHAP ppp-watch
Cross references:


1. Topic:

One security bug and several functionality bugs have been fixed
in a new release of initscripts.

2. Problem description:

A /tmp race existed in /etc/profile.d/lang.csh. Users who had
csh/tcsh as their login shell could be vulnerable to having
arbitrary shell code run by their shell on login.

On PPP connections, CHAP authentication did not always work. New
DNS entries were not always correctly added to the /etc/resolv.conf
file. Also, there was a theoretical chance that random processes
could be sent signals by ppp-watch, though no outside process could
affect which processes would be signaled, and in every known case
the signals are sent to impossible process ids and therefore have
no effect.

Other various bugs present in the initscripts that shipped with
Red Hat Linux 6.1 are fixed, including:

– linuxconf-created IP aliases did not work
– linuxconf-created static routes may not work
– path to ipx_interface was incorrect
– /sbin/service did not work
– incompatibility with devfs
– inability to shut down cleanly with quotas
– any user could force ‘interactive’ startup on next reboot

It is recommended that users of Red Hat Linux 6.1 update to the
fixed packages.

These packages are GPG signed by Red Hat, Inc. for security. Our
key is available at:
http://www.redhat.com/corp/contact.html

You can verify each package with the following command:
rpm –checksig

If you only wish to verify that each package has not been
corrupted or tampered with, examine only the md5sum with the
following command: r
pm –checksig –nogpg
