Debian Security Advisory DSA 292-2 security@debian.org
http://www.debian.org/security/ Martin Schulze
April 23rd, 2003 http://www.debian.org/security/faq
--------------------------------------------------------------------------

Package : mime-support
Vulnerability : insecure temporary file creation
Problem-Type : local
Debian-specific: no

Unfortunately yesterday's update for mime-support did not exactly work
as expected, which requires an update. For completeness we include
the advisory text:

Colin Phipps discovered several problems in mime-support, that contains
support programs for the MIME control files 'mime.types' and
'mailcap'.
When a temporary file is to be used it is created insecurely, allowing
an attacker to overwrite arbitrary under the user id of the person
executing run-mailcap, most probably root. Additionally the program did
not properly escape shell escape characters when executing a command.
This is unlikely to be exploitable, though.

For the stable distribution (woody) these problems have been fixed in
version 3.18-1.2.

For the old stable distribution (potato) these problems have been
fixed in version 3.9-1.2.

For the unstable distribution (sid) these problems have been
fixed in version 3.22-1 (same as DSA 292-1).

We recommend that you upgrade your mime-support packages.


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

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

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

apt-get update

apt-get upgrade

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