[K12OSN] Linux vulnerabilities?

[Jonathan Kallay]

Hi all,
  I'm trying to push K12LTSP to the district IT office.  The managers are in a strange position where they seem to be tiptoeing around the 'techies' to which they have outsourced some of the network administration.  These 'techies' refuse to have anything to do with a single Linux box on a network of several thousand computers, professing at once both ignorance about Linux and at the same time spouting all kinds of misinformation about how open source software is insecure.  I've been told that it would be to my benefit to identify what the big Linux security holes are, to 'get everything out in the open,' so to speak.  Because of the openness of the operating system, the only security holes I know of are simply the result of system admin error or ignorance.  Can anyone help me out?
