Critical Debian advisory addresses filename sanitizing flaw in lxr. Remote attackers can exploit this to access sensitive files.
There is a vulnerability that allows a remote attacker to read arbitrary files on the host system as user www-data.

Summary

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
