There was a fascinating RHEL bug reported, in the use of pygrub, because pygrub would read the grub contents from the DomU at boot time and this created an interesting security risk for the pygrub program itself.Hi, I am planning to offer a hosted xen server within my locality. My question is, is there any security issue that I should be aware of. I am currently letting user to choose which kernel they want to boot. Is there any possibility, that with, say a recompiled kernel or kernel module, a user can actually gain access to the Dom0? Thank you Azrul Rahim A much bigger risk is the standard co-location risk of "these machines I don't control are inside my network: how do I protect myself from them?". _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
