Package : sendmail
Vulnerability : insecure temporary files
Problem-Type : local
Debian-specific: no

Paul Szabo discovered bugs in three scripts included in the sendmail
package where temporary files were created insecurely (expn,
checksendmail and doublebounce.pl). These bugs could allow an
attacker to gain the privileges of a user invoking the script
(including root).

For the stable distribution (woody) these problems have been fixed in
version 8.12.3-6.4.

For the old stable distribution (potato) these problems have been fixed
in version 8.9.3-26.1.

For the unstable distribution (sid) these problems have been fixed in
version 8.12.9-2.

We recommend that you update your sendmail package.

Upgrade Instructions
- --------------------

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.
