    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 only.

    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

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

    4. Relevant releases/architectures:
    Red Hat Linux 6.1, Intel, Sparc

    5. Obsoleted by:

    6. Conflicts with:

    7. RPMs required:


    ftp://updates.Red Hat.com/6.1/i386/



    ftp://updates.Red Hat.com/6.1/sparc/



    ftp://updates.Red Hat.com/6.1/SRPMS


    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
    44190a9a34298d590529b0385111d3d6  i386/initscripts-4.70-1.i386.rpm
    257fa5ae56d10113a83520045f6cbd47  sparc/initscripts-4.70-1.sparc.rpm
    589280ce8452996c5338c155c1828872  SRPMS/initscripts-4.70-1.src.rpm
    These packages are GPG signed by Red Hat, Inc. for security. Our key is available at:
    http://www.Red Hat.com/corp/contac t.html

    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

    Note that you need RPM >= 3.0 to check GnuPG keys.
