		   Red Hat, Inc. Security Advisory

Synopsis:		new initscripts packages available (/tmp race)
Advisory ID:		RHSA-1999:052-04
Issue date:		1999-11-08
Updated on:		1999-11-30
Keywords:		lang.csh resolv.conf CHAP ppp-watch default route
Cross references:	

Revision History:
 1999-11-30: Update to fix a networking bug introduced in 4.67-1.
 1999-11-23: Update to fix a typo in the system font setting in
             rc.sysinit introduced in 4.67-1.
 1999-11-22: Update to fix several functionality bugs.  No new
             security bugs were found.  (initscripts-4.67)
             Note: only the new bugs apply to the Sparc release,
             so this is a security update for the Intel platform

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

1999-11-22: More bugs fixed, including
- pppd default route problem
- more possible CHAP authentication bugs (with older PPP configurations)
- netcfg and linuxconf could fail to bring up PPP connections
- in failure cases, pppd error messages could fill logs
- some device alias configurations were not properly initialized

1999-11-23: One bug fix.
- We apologize for the typo in rc.sysinit. Those responsible have
  been sacked.
1999-11-30: More bugs fixed, including
- We apologize again for the duplicate default routes. Those responsible
  for sacking the people who have just been sacked have been sacked.
- fixed loading of sound mixer settings
- fixed boot-time logging

8. Solution:

For each RPM for your particular architecture, run:
    rpm -Uvh <filename>
where filename is the name of the RPM.

9. Verification:

MD5 sum                           Package Name

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:
You can verify each package with the following command:
    rpm --checksig  <filename>

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
    rpm --checksig --nogpg <filename>
