Hidden process + zombie shell found on new install of ubuntu 8.04 - what do i do
I upgraded to the latest ubuntu release, Hardy Heron 8.04, and noticed a shell process marked in the system monitor called 'sh Zombie'.
It has a 4-integer PID and uses no memory (says Memory N/A); it opens no files and has no memory maps, and appears to do nothing.
I had a poke around using unhide proc and found another, different PID, this time a hidden one with 5-integers:
Found HIDDEN PID: XXXXX
can't find any info on what to do about zombie scripts or hidden pid's
How worried should i be? i'm not a security expert or anything, but am usually pretty careful about passwords and thought ubuntu was safe - it was the hardest box to hack at a recent competition - the only notebook to remain unhacked at the end of the competition is the Sony VAIO running Ubuntu 7.10.
Anyone know of security flaws in ubuntu 8.04 ?
