Package        : debmake
Vulnerability  : insecure temporary files
Problem-Type   : local
Debian-specific: yes
CVE ID         : CAN-2004-1179
Debian Bug     : 286382

Javier Fernández-Sanguino Peña noticed that the debstd script from
debmake, a deprecated helper package for Debian packaging, created
temporary directories in an insecure manner.  This can be exploited by
a malicious user to overwrite arbitrary files owned by the victim.

For the stable distribution (woody) this problem has been fixed in
version 3.6.10.woody.1.

For the unstable distribution (sid) this problem has been fixed in
version 3.7.7.

We recommend that you upgrade your debmake 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.
