Debian: New analog packages fix cross-site scripting vulnerability

Yuji Takahashi discovered a bug in analog which allows a cross-site scripting type attack. It is easy for an attacker to insert arbitrary strings into any web server logfile. If these strings are then analysed by analog, they can appear in the report. By this means an attacker can introduce arbitrary Javascript code, for example, into an analog report produced by someone else and read by a third person. Analog already attempted to encode unsafe characters to avoid this type of attack, but the conversion was incomplete. Fixed packages can be obtained from security.debian.org.

Package        : analog
Vulnerability  : cross-site scripting 
Problem-Type   : remote
Debian-specific: no

Yuji Takahashi discovered a bug in analog which allows a cross-site
scripting type attack.  It is easy for an attacker to insert arbitrary
strings into any web server logfile.  If these strings are then
analysed by analog, they can appear in the report.  By this means an
attacker can introduce arbitrary Javascript code, for example, into an
analog report produced by someone else and read by a third person.
Analog already attempted to encode unsafe characters to avoid this
type of attack, but the conversion was incomplete.

This problem has been fixed in the upstream version 5.22 of analog.
Unfortunately patching the old version of analog in the stable
distribution of Debian instead is a very large job that defeats us.

We recommend that you upgrade your analog package immediately.

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.
