Re: Xen Security Advisory 27 (CVE-2012-5511) - several HVM operations do not validate the range of their inputs

All,

This advisory required two different CVE IDs - not one - because the 
stack-based buffer overflow was fixed in a different version than the 
other issues.  CVE assigns different IDs when bugs are not present in the 
same exact set of versions.

CVE-2012-5511 - use this, but only for the stack-based buffer overflow 
that was fixed in 4.2.

CVE-2012-6333 - new ID for the other "large input" validation issues that 
lead to the physical CPU hang, which were NOT fixed in 4.2.
