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.

Source packages:

  ftp://updates.redhat.com/6.1/SRPMS/initscripts-4.63-1.src.rpm

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  <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>
