Debian Security Advisory DSA-024-1                       security@debian.org

Package        : cron
Vulnerability  : local insecure crontab handling
Debian-specific: no

The FreeBSD team has found a bug in the way new crontabs were handled
which allowed malicious users to display arbitrary crontab files on
the local system.  This only affects valid crontab files so can't be
used to get access to /etc/shadow or something.  crontab files are not
especially secure anyway, as there are other ways they can leak.  No
passwords or similar sensitive data should be in there.

We recommend you upgrade your cron packages.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

You may use an automated update by adding the resources from the
footer to the proper configuration.


Debian GNU/Linux 2.2 alias potato
- ------------------------------------

  Potato was released for the alpha, arm, i386, m68k, powerpc and sparc
  architectures.
