Hi

I am wondering about last line..can anyone throw some light what exactly it is doing,

By the way which release of Solaris 10 are you using? Kernel patch level?

5.10 Generic_118833-24

Thanks, Do you know it is happening in solaris 10 also ? I wonder how exactly can I try to see if this vulnerability is there still or not ?
