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