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.

tampered with, examine only the md5sum with the following command:
rpm --checksig --nogpg <filename>
