CVE-2017-8903

CVE-2017-8903 affects Xen on 64-bit platforms (Xen through 4.8.x) where page tables are mishandled after an IRET hypercall. This could let a PV guest OS user execute arbitrary code on the host OS (XSA-213). Connected sources corroborate the body of the vulnerability (XSA-213) and describe the hos...

Xen Hypervisor Multiple Vulnerabilities (XSA-213 - XSA-215)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by multiple vulnerabilities : - An information disclosure vulnerability exists in the getuser function due to permissions for accessing MMIO ranges being checked only after accessing them. A...

x86: 64bit PV guest breakout via pagetable use-after-mode-change

ISSUE DESCRIPTION 64-bit PV guests typically use separate root page tables for their kernel and user modes. Hypercalls are accessible to guest kernel context only, which certain hypercall handlers make assumptions on. The IRET hypercall replacing the identically name CPU instruction is used by...

FreeBSD : FreeBSD -- Local privilege escalation in IRET handler (0dfa5dde-600a-11e6-a6c3-14dae9d210b8)

If the kernel-mode IRET instruction generates an SS or NP exception, but the exception handler does not properly ensure that the right GS register base for kernel is reloaded, the userland GS segment may be used in the context of the kernel exception handler. Impact : By causing an IRET with SS o...

The vulnerability of Xen hypervisors, which allows a malicious actor to trigger a service failure

The vulnerability of the compatiret function in Xen supervisors is related to resource management errors. Exploiting this vulnerability can allow a malicious actor, operating locally, to trigger a service failure by calling the hypercalliret function with the EFLAGS.VM parameter set...

kernel: x86-64: IRET faults during NMIs processing

A flaw was found in the way the Linux kernel handled IRET faults during the processing of NMIs. An unprivileged, local user could use this flaw to crash the system or, potentially although highly unlikely, escalate their privileges on the system...
