Hi

I haven't found if there was already a request for this.

In Debian Bugtracker it was closed [1] today. It is possible due to
a bug in bcron-exec that cron jobs get access to the temporary
output files from other jobs that are still running. This is also
mentioned in upstream's NEWS[2]. The commit to fix this on github
should be[3]. Even it looks bcron is not broadly used, could the
above get a CVE?

 Regards, Salvatore

This is news to me. Please use CVE-2012-6110 for this issue.
