Package        : lxr
Vulnerability  : missing filename sanitizing
Problem-Type   : remote
Debian-specific: no

Upstream developers of lxr, a general hypertext cross-referencing
tool, have been alerted of a vulnerability that allows a remote
attacker to read arbitrary files on the host system as user www-data.
This could disclose local files that were not meant to be shared with
the public.

For the stable distribution (woody) this problem has been
fixed in version 0.3-3.

The old stable distribution (potato) is not affected since it does not
contain an lxr package.

For the unstable distribution (sid) this problem has been
fixed in version 0.3-4.

We recommend that you upgrade your lxr 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
