Weekly Linux Security Roundup

[SP] Here is the weekly Linux Security Roundup by Kurt Seifried from Security Portal. "Not a bad week, I'm at a security convention (heavily mainframe and especially S/390 oriented) currently having a great time (the mainframe people here still mostly view Linux as a toy, telling them it's been ported to their platforms is quite fun). Not to many problems this week, and some new tools and versions of popular software."
