Title:
Warning messages from stat printed on installation with no user
crontabs
Status in cron package in Ubuntu:
Confirmed
Status in cron source package in Xenial:
Triaged
Status in cron source package in Bionic:
Triaged
Bug description:
On installation of cron on a new system, or (I expect) an upgrade with
no user crontab files the following is printed:
Setting up cron (3.0pl1-128.1ubuntu1.1) ...
stat: cannot stat '*': No such file or directory
stat: cannot stat '*': No such file or directory
stat: cannot stat '*': No such file or directory
Warning: * is not a regular file!
This is related to the fix for CVE-2017-9525 introduced in
3.0pl1-128.1ubuntu1.1. The for loop at line 66 of cron.postinst needs
to have a guard like the following added to it:
[ "$tab_name" = "*" ] && continue
We have observed this with Bionic, I haven't checked any other Ubuntu
releases.
Cheers,
Andrew
