1. Problem Description
The webmail frontend IMP has a cross site scripting problem,

7.3 Installing Fixed Packages
Upgrade the affected packages with the following commands:
rpm -Fvh horde-1.2.7-1.i386.rpm imp-2.2.7-1.i386.rpm
Update notes:
If horde was activated in the apache module
"/etc/httpd/modules/mod_php4_horde.conf" you will have to
reconfigure it by changing "deny from all" to "allow from all".
Do not run "/usr/lib(exec)/horde/horde.setup" if you already
have started the script before the update. If you run the
script again, all passwords will be changed back to the
default value and you will have to change them manually in
"/home/httpd/html/horde/imp/config/defaults.php3" and
"/home/httpd/phplib/local.inc"
8. OpenLinux 3.1 Workstation
not vulnerable
