Package        : ppp
Vulnerability  : programming error
Problem type   : local
Debian-specific: no
CVE ID         : CVE-2006-2194

Marcus Meissner discovered that the winbind plugin in pppd does not
check whether a setuid() call has been successful when trying to drop
privileges, which may fail with some PAM configurations.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in
version 2.4.3-20050321+2sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 2.4.4rel-1.

We recommend that you upgrade your ppp 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

You may use an automated update by adding the resources from the
