Package: cron Version: 3.0pl1-116 Severity: normal Hi,
Files in /etc/cron.d that have group write permissions will not have their cronjobs run but if /etc/cron.d/ contains a symlink to a file with group write permissions the cron jobs in that file are run. After the content of the file is changed cron will then refuse to run the jobs. The following script demonstrates the problem: ---------------------<snip>----------------- # Tidy up before we start. rm -f /etc/cron.d/foo /tmp/foo sleep 60 # Establish crontab cat - >/tmp/foo <<EOF * * * * * root printf 'Running\n' EOF chmod g=w /tmp/foo ln -s /tmp/foo /etc/cron.d/ # Permissions are: ## ls -lh /tmp/foo #-rw-r--r-- 1 root root 34 May 3 10:56 /tmp/foo sleep 60 # Cron job runs (email delivered to root) cat - >/tmp/foo <<EOF #* * * * * root printf 'Running\n' EOF sleep 60 # Cron job does not run cat - >/tmp/foo <<EOF * * * * * root printf 'Running\n' EOF sleep 60 # Cron job still does not run ---------------------<snip>----------------- -- Package-specific info: --- EDITOR: --- usr/bin/editor: /bin/nano --- /usr/bin/crontab: -rwxr-sr-x 1 root crontab 30248 Dec 18 17:46 /usr/bin/crontab --- /var/spool/cron drwxr-xr-x 5 root root 4096 Mar 8 2005 /var/spool/cron --- /var/spool/cron/crontabs drwx-wx--T 2 root crontab 4096 Jan 27 16:10 /var/spool/cron/crontabs -- System Information: Debian Release: 6.0.1 APT prefers stable APT policy: (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.32-5-686 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages cron depends on: ii adduser 3.112+nmu2 add and remove users and groups ii debianutils 3.4 Miscellaneous utilities specific t ii dpkg 1.15.8.10 Debian package management system ii libc6 2.11.2-10 Embedded GNU C Library: Shared lib ii libpam-runtime 1.1.1-6.1 Runtime support for the PAM librar ii libpam0g 1.1.1-6.1 Pluggable Authentication Modules l ii libselinux1 2.0.96-1 SELinux runtime shared libraries ii lsb-base 3.2-23.2squeeze1 Linux Standard Base 3.2 init scrip Versions of packages cron recommends: ii lockfile-progs 0.1.15 Programs for locking and unlocking ii postfix [mail-transport-agent 2.7.1-1 High-performance mail transport ag Versions of packages cron suggests: ii anacron 2.3-14 cron-like program that doesn't go pn checksecurity <none> (no description available) ii logrotate 3.7.8-6 Log rotation utility Versions of packages cron is related to: pn libnss-ldap <none> (no description available) pn libnss-ldapd <none> (no description available) pn libpam-ldap <none> (no description available) pn libpam-mount <none> (no description available) pn nis <none> (no description available) pn nscd <none> (no description available) -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
