Package        : devscripts
Vulnerability  : missing input sanitation
Problem type   : remote
Debian-specific: yes
CVE Id(s)      : CVE-2009-2946

Raphael Geissert discovered that uscan, a program to check for
availability of new source code versions which is part of the
devscripts package, runs Perl code downloaded from potentially
untrusted sources to implement its URL and version mangling
functionality.  This update addresses this issue by reimplementing the
relevant Perl operators without relying on the Perl interpreter,
trying to preserve backwards compatibility as much as possible.

For the old stable distribution (etch), this problem has been fixed in
version 2.9.26etch4.

For the stable distribution (lenny), this problem has been fixed in
version 2.10.35lenny6.

For the unstable distribution (sid), this problem will be fixed in
version 2.10.54.

We recommend that you upgrade your devscripts 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.
