Debian Security Advisory DSA 102-2                                        Martin Schulze
January 18th, 2002

Package        : at
Vulnerability  : daemon exploit
Problem-Type   : local
Debian-specific: no

Basically, this is the same Security Advisory as DSA 102-1, except
that the uploaded binary packages really fix the problem this time.
Unfortunately the bugfix from DSA 102-1 wasn't propagated properly due
to a packaging bug.  While the file parsetime.y was fixed, and should be generated from it, from the original
source was still used.  This has been fixed now.

The original advisory said:

zen-parse found a bug in the current implementation of at which leads
into a heap corruption vulnerability which in turn could potentially
lead into an exploit of the daemon user.

This has been fixed in at 3.1.8-10.2 for the stable Debian release and
3.1.8-11 for the unstable and testing release.  Packages for unstable
have just been uploaded into  <>.  We
recommend that you upgrade your at packages immediately since an
exploit has already been published.

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

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

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