Xen Security Advisory 82 (CVE-2013-6885) - Guest triggerable AMD CPU erratum may cause host hang
...ions May Cause Core Hang" describes a situation under which a CPU core may hang. IMPACT ====== A malicious guest administrator can mount a denial of service attack affecting the whole system. VULNERABLE SYSTEMS ================== The vulnerability is applicable only to family 16h model 00h-0fh AMD CPUs. Such CPUs running Xen versions 3.3 onwards are vulnerable. We have not checked earlier versions of Xen. HVM guests can always exploit the vulnerability if it is present. PV guests can exploit the vulnerability only if they have been granted access to physical device(s). Non-AMD CPUs a...

pxelinux bug's
Hello Peter, The attached patch contains three small (although 2 of them are fundamental :) fixes for pxelinux 1. Alignment error when more than one initramfs are loaded using initrd - the alignment of the last disk is discarded in calculations but is ALWAYS present when the loading procedure is called. As a result - the second image (cpio) is not recognized. 2. On some platforms

unload memdisk+FreeDOS => local boot
Sensei H. Peter Anvin, I have successfully modified/enhanced memdisk so that one can chainload a local operating system after running diskless FreeDOS. I would like your advice regarding the appropriate interface for invoking this functionality. In addition, I would like to know what steps to take so that you feel comfortable considering including this in the standard syslinux distribution.
