Summary:

This event is generated when an attempt is made to gain information on installed packages on OpenLINUX.

Impact:

This is a serious information leak, since an attack could then attempt to determine and exploit any vulnerable packages.

vulnerability exists which will allow a remote user to list all
packages/versions installed on the system. This information will be 
useful for an attacker to further compromise a system.
