https://bugzilla.novell.com/show_bug.cgi?id=786096 https://bugzilla.novell.com/show_bug.cgi?id=786096#c0 Summary: cron does not close file descriptors before invocation of commands Classification: openSUSE Product: openSUSE 12.2 Version: Final Platform: All OS/Version: openSUSE 12.2 Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: f+novell@congenio.de QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:16.0) Gecko/20100101 Firefox/16.0 When I use lvm2 commands within a shell script that is being called from cron, I always get errors like these in the cron mails: File descriptor 5 (/var/spool/cron/tabs) leaked on lvcreate invocation. Parent PID 15139: /bin/sh File descriptor 6 (/etc/cron.d) leaked on lvcreate invocation. Parent PID 15139: /bin/sh File descriptor 7 (/etc/crontab) leaked on lvcreate invocation. Parent PID 15139: /bin/sh It shows that lvm2 regards open file descriptors as a security hole, complains and then closes them. This behaviour can be temporarily fixed by setting the undocumented environment variable LVM_SUPPRESS_FD_WARNINGS. However, it should be fixed in cron itself - there is a similar bug in Debian, so the bug could be fixed upstream (maybe it already is). Reproducible: Always Steps to Reproduce: Use any lvm2 command in a cron script. Actual Results: Mail containing errors about leaked file descriptors that cron left open: File descriptor 5 (/var/spool/cron/tabs) leaked on lvcreate invocation. Parent PID 15139: /bin/sh File descriptor 6 (/etc/cron.d) leaked on lvcreate invocation. Parent PID 15139: /bin/sh File descriptor 7 (/etc/crontab) leaked on lvcreate invocation. Parent PID 15139: /bin/sh Expected Results: No error output. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There may be credentials in those files which are readably by cron but not by other users. So, IMO, there may be a privilege elevation issue, but those files can be seen only by the command that is being called, so the chance is slim. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From Vincent Danen:

Ok, so did some more digging based on some info from one of our developers that we had patched this in Fedora. Looks like this patch introduced the leak on 2011-04-28: http://git.fedorahosted.org/cgit/cronie.git/commit/src/cron.c?id=acdf4ae8456... +28f54582 And this patch reverted it on 2011-06-29: http://git.fedorahosted.org/cgit/cronie.git/commit/src/cron.c?id=b19007ca9fd... +1d5e0419 So it looks like only 1.4.8 was affected by this (which, judging by the patch in your bugzilla is the same version you're seeing as affected). That might be a better patch to use than what you're using. Anyways, this only affects 1.4.8 (for any others using cronie and concerned as to whether or not they might be affected).
