From redhat-watch-list@redhat.com Wed Nov 10 23:00:27 1999 From: redhat-watch-list@redhat.com To: BUGTRAQ@SECURITYFOCUS.COM Date: Tue, 9 Nov 1999 16:21:43 -0000 Subject: [RHSA-1999:052-1] new initscripts available (/tmp problems) *This message was transferred with a trial version of CommuniGate(tm) Pro* --------------------------------------------------------------------- Red Hat, Inc. Security Advisory Synopsis: new initscripts packages available (/tmp race) Advisory ID: RHSA-1999:052-01 Issue date: 1999-11-08 Updated on: 1999-11-08 Keywords: lang.csh resolv.conf CHAP ppp-watch Cross references: --------------------------------------------------------------------- 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. 3. Bug IDs fixed (http://developer.redhat.com/bugzilla for more info): Security problem in lang.csh: 6645 Missing DNS entries: 6664, 6649 CHAP: 6664, 6646, 6506, 6586 Linuxconf issues: 5784, 5976, 6039, 6069, 6162, 6777 Others: 5646, 5959, 6252, 6286, 6300, 6301, 6527 4.
