Package        : polygen
Vulnerability  : programming error
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2005-2656
Debian Bug     : 325468

Justin Rye noticed that polygen generates precompiled grammar objects
world-writable, which can be exploited by a local attacker to at least
fill up the filesystem.

The old stable distribution (woody) does not contain the polygen package.

For the stable distribution (sarge) this problem has been fixed in
version 1.0.6-7sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 1.0.6-9.

We recommend that you upgrade your polygen 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
footer to the proper configuration.
