Description Mark J. Cox 2005-06-29 07:32:38 UTC
+++ This bug was initially created as a clone of Bug #154920 +++

crontab in Vixie cron 4.1, when running with the -e option, allows local users
to read the cron files of other users by changing the file being edited to a
symlink.  NOTE: there is insufficient information to know whether this is a
duplicate of CVE-2001-0235.

Comment 2 Josh Bressers 2005-07-08 21:25:15 UTC
Our current fix for this issue is not complete.  A race condition still exists
between the time we lstat the file in question, and when we open the file.

Comment 3 Jason Vas Dias 2005-07-11 23:37:05 UTC
This is now fixed with vixie-cron-4.1-8.EL3, available from:
The race condition has been circumvented: the fopen() is done as
the non-root user, which also fixes the case when the temporary
file is made into a hardlink to a root owned file.
Please try out the new version and let me know of any issues - thanks.

Comment 6 Jason Vas Dias 2005-10-14 15:32:26 UTC
This bug is fixed with vixie-cron-4.1-8_EL3, available from:
