---------------------------------------------------------------------

1. Topic:

Updated packages for analog are available which fix a cross-site  
scripting problem and a denial of service problem.

2. Relevant releases/architectures:

Red Hat Powertools 7.1 - alpha, i386

3. Problem description:

Analog is a web server logfile analysis program.  

Yuji Takahashi discovered a bug in analog versions prior to 5.2.2 which
allows a cross-site scripting attack when an attacker can insert arbitrary
strings into a web server logfile. Analog then performs an analysis on all
strings in the logfile and reports it. An attacker can exploit this
vulnerability, for example, by introducing arbitrary Javascript code into
an analog report produced by one user and read by a third person. 
 
Additionally a problem was discovered in the optional CGI front end form
interface to analog, anlgform.pl in versions prior to 5.23.  An attacker
who has access to this program could cause the web server error log to fill.

All users of analog are advised to upgrade to the errata packages
containing analog version 5.24 which is not affected by these vulnerabilities.

4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory *only* contains
the desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. RPMs required:

Red Hat Powertools 7.1:

SRPMS: 
ftp://updates.Red Hat.com/7.1/en/powertools/SRPMS/analog-5.24-1.src.rpm

alpha: 
ftp://updates.Red Hat.com/7.1/en/powertools/alpha/analog-5.24-1.alpha.rpm 
ftp://updates.Red Hat.com/7.1/en/powertools/alpha/analog-form-5.24-1.alpha.rpm

i386: 
ftp://updates.Red Hat.com/7.1/en/powertools/i386/analog-5.24-1.i386.rpm 
ftp://updates.Red Hat.com/7.1/en/powertools/i386/analog-form-5.24-1.i386.rpm
