User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Debian Frank Lichtenheld and Nico Golde discovered that WML, an off-line HTML generation toolkit, creates insecure temporary files in the eperl and ipp backends and in the wmg.cgi script, which could lead to local denial of service by overwriting files.

Debian Security Advisory DSA 1492-2                    security@debian.org

Package        : wml
Vulnerability  : insecure temporary files
Problem type   : local
Debian-specific: no
CVE IDs        : CVE-2008-0665 CVE-2008-0666
Debian Bugs    : 463907 471345

The security update DSA 1492-1 fixed the security problem below but
introduced a new problem by not removing temporary directories in the
ipp backend.  This update corrects this.

For completeness here is the original advisory text:

   Frank Lichtenheld and Nico Golde discovered that WML, an off-line
   HTML generation toolkit, creates insecure temporary files in the
   eperl and ipp backends and in the wmg.cgi script, which could lead
   to local denial of service by overwriting files.

The old stable distribution (sarge) is not affected.

For the stable distribution (etch) this problem has been fixed in
version 2.0.11-1etch2.

For the unstable distribution (sid) this problem has been fixed in
version 2.0.11ds1-0.2.

We recommend that you upgrade your wml 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 at the end of this advisory:

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.
