FreeBSD : xen-kernel -- guest 32-bit ELF symbol table load leaking host data (5555120d-ba4d-11e6-ae1b-002590263bf5)
The Xen Project reports : Along with their main kernel binary, unprivileged guests may arrange to have their Xen environment load kernel symbol tables for their use. The ELF image metadata created for this purpose has a few unused bytes when the symbol table binary is in 32-bit ELF format. These...
FreeBSD : xen-kernel -- x86: Disallow L3 recursive pagetable for 32-bit PV guests (45ca25b5-ba4d-11e6-ae1b-002590263bf5)
The Xen Project reports : On real hardware, a 32-bit PAE guest must leave the USER and RW bit clear in L3 pagetable entries, but the pagetable walk behaves as if they were set. The L3 entries are cached in processor registers, and don't actually form part of the pagewalk. When running a 32-bit PV...

guest 32-bit ELF symbol table load leaking host data
ISSUE DESCRIPTION Along with their main kernel binary, unprivileged guests may arrange to have their Xen environment load kernel symbol tables for their use. The ELF image metadata created for this purpose has a few unused bytes when the symbol table binary is in 32-bit ELF format. These unused...
x86 task switch to VM86 mode mis-handled
ISSUE DESCRIPTION LDTR, just like TR, is purely a protected mode facility. Hence even when switching to a VM86 mode task, LDTR loading needs to follow protected mode semantics. This was violated by the code. IMPACT On SVM AMD hardware: a malicious unprivileged guest process can escalate its...
xen-kernel -- x86 null segments not always treated as unusable
The Xen Project reports: The Xen x86 emulator erroneously failed to consider the unusability of segments when performing memory accesses. The intended behaviour is as follows: The user data segment %ds, %es, %fs and %gs selectors may be NULL in 32-bit to prevent access. In 64-bit, NULL has a...
