[Xen-announce] Xen Project Maintenance Releases Available (Versions 4.4.1, 4.3.3, 4.2.5)
I am pleased to announce the release of Xen 4.4.1, 4.3.3 and 4.2.5. We recommend that all users of the 4.4, 4.3 and 4.2 stable series update to the latest point release.
= Xen 4.4.1 =
Xen 4.4.1 is available immediately from its git repository http://xenbits.xen.org/gitweb/?p=xen.git;a=shortlog;h=refs/heads/stable-4.4
(tag RELEASE-4.4.1) or from the XenProject download pagehttp://www.xenproject.org/downloads/xen-archives/supported-xen-44-series/xen-441.html
This fixes the following critical vulnerabilities (also see http://xenbits.xen.org/xsa/):
* CVE-2014-2599 / XSA-89: HVMOP_set_mem_access is not preemptible
* CVE-2014-3125 / XSA-91: Hardware timer context is not properly context switched on ARM
* CVE-2014-3124 / XSA-92: HVMOP_set_mem_type allows invalid P2M entries to be created
* CVE-2014-2915 / XSA-93: Hardware features unintentionally exposed to guests on ARM
* CVE-2014-2986 / XSA-94: ARM hypervisor crash on guest interrupt controller access
* CVE-2014-3714,CVE-2014-3715,CVE-2014-3716,CVE-2014-3717 / XSA-95: input handling vulnerabilities loading guest kernel on ARM
* CVE-2014-3967,CVE-2014-3968 / XSA-96: Vulnerabilities in HVM MSI injection
* CVE-2014-3969 / XSA-98: insufficient permissions checks accessing guest memory on ARM
* CVE-2014-4021 / XSA-100: Hypervisor heap contents leaked to guests
* CVE-2014-4022 / XSA-101: information leak via gnttab_setup_table on ARM
* CVE-2014-5147 / XSA-102: Flaws in handling traps from 32-bit userspace on 64-bit ARM
* CVE-2014-5148 / XSA-103: Flaw in handling unknown system register access from 64-bit userspace on ARM
Additionally a workaround for CVE-2013-3495 / XSA-59 (Intel VT-d Interrupt Remapping engines can be evaded by native NMI interrupts) has been put in place. However, at this point we can't guarantee that all affected chipsets are being covered; Intel is working diligently on providing us with a complete list.
Apart from those there are many further bug fixes and improvements.
= Xen 4.3.3 =
Xen 4.3.3 is available immediately from its git repository http://xenbits.xen.org/gitweb/?p=xen.git;a=shortlog;h=refs/heads/stable-4.3 (tag RELEASE-4.3.3) or from the XenProject download page http://www.xenproject.org/downloads/xen-archives/supported-xen-43-series/xen-433.html
