Package        : python2.3
Vulnerability  : buffer overflow
Problem-Type   : local(remote)
Debian-specific: no
CVE ID         : CVE-2006-4980
Debian Bug     : 391589

Benjamin C. Wiley Sittler discovered that the repr() of the Python 
interpreter allocates insufficient memory when parsing UCS-4 Unicode
strings, which might lead to execution of arbitrary code through
a buffer overflow.

For the stable distribution (sarge) this problem has been fixed in
version 2.3.5-3sarge2. Due to build problems this update lacks fixed
packages for the Alpha and Sparc architectures. Once they are sorted
out, fixed binaries will be released.

For the unstable distribution (sid) this problem has been fixed in
version 2.3.5-16.

We recommend that you upgrade your Python 2.3 packages.


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.
