description of vulnerabilities in update packages

[Darrell Esau]

Hello all,

With RedHat 7.3, 8 and 9, I used to subscribe to RHN for a few of my 
internet-connected boxes. 

I thought the service was great, but I've since moved to Fedora Core.  During 
the first few weeks of FC, I had trouble with up2date, so I made the switch 
to Yum.

I missed several of the nice features of RHN, but I've managed to make yum do 
almost everything except one:

With RHN, (while using up2date), each package had a description of the 
vulnerabilties/descriptions of the problems, which told how serious the 
problem was.  I would use this information to tell if I needed to update the 
package right away, or if it could wait.

That data seems to no longer be available with up2date.. clicking on the "View 
Advisory" button yeilds something like "no advisory for this package".. and I 
don't know if it ever was available for yum.

Is there any easy way to find this information?

Thanks,
-d
