Description Jan Lieskovsky 2010-02-16 06:54:10 EST
Race condition was found in the way vixie-cron and cronie
used to set up timestamp (modification time) for crontab
file of the individual user by editing the file. A local
attacker could use this flaw to conduct unintended changes
of timestamp (modification time) value against various
system files, potentially leading to denial of their service.
