SUSE SLED12 / SLES12 Security Update : xen (SUSE-SU-2017:2864-1)

This update for xen fixes several issues: These security issues were fixed : - CVE-2017-5526: The ES1370 audio device emulation support was vulnerable to a memory leakage issue allowing a privileged user inside the guest to cause a DoS and/or potentially crash the Qemu process on the host...

Xen Hypervisor TLB Flush Request Handling Race Condition System Memory Access Guest-to-Host Privilege Escalation (XSA-241)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a race condition that is triggered when handling TLB flush requests. This allows an attacker on the guest to access all system memory, allowing them to cause a denial of service, disclose...

Stale TLB entry due to page type release race

ISSUE DESCRIPTION x86 PV guests effect TLB flushes by way of a hypercall. Xen tries to reduce the number of TLB flushes by delaying them as much as possible. When the last type reference of a page is dropped, the need for a TLB flush before the page is re-used is recorded. If a guest TLB flush...
