Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
Multiple vulnerabilities have been found in Xen, allowing attackers on |
| 20 |
a Xen Virtual Machine to execute arbitrary code, cause Denial of |
| 21 |
Service, or gain access to data on the host. |
| 22 |
|
| 23 |
Background |
| 24 |
========== |
| 25 |
|
| 26 |
Xen is a bare-metal hypervisor. |
| 27 |

Description |
| 42 |
=========== |
| 43 |
|
| 44 |
Multiple vulnerabilities have been discovered in Xen. Please review the |
| 45 |
CVE identifiers referenced below for details. |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
Guest domains could possibly gain privileges, execute arbitrary code, |
| 51 |
or cause a Denial of Service on the host domain (Dom0). Additionally, |
| 52 |
guest domains could gain information about other virtual machines |
| 53 |
running on the same host or read arbitrary files on the host. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
The CVEs listed below do not currently have fixes, but only apply to |
| 59 |
Xen setups which have "tmem" specified on the hypervisor command line. |
| 60 |
TMEM is not currently supported for use in production systems, and |
| 61 |
administrators using tmem should disable it. |
| 62 |
Relevant CVEs: |
| 63 |
* CVE-2012-2497 |
| 64 |
* CVE-2012-6030 |
| 65 |
* CVE-2012-6031 |
| 66 |
* CVE-2012-6032 |
| 67 |
* CVE-2012-6033 |
| 68 |
* CVE-2012-6034 |
| 69 |
* CVE-2012-6035 |
| 70 |
* CVE-2012-6036 |
| 71 |
|
| 72 |
Resolution |
| 73 |
========== |
| 74 |
|
| 75 |
All Xen users should upgrade to the latest version: |
| 76 |
|
| 77 |
# emerge --sync |
| 78 |
# emerge --ask --oneshot --verbose ">=app-emulation/xen-4.2.2-r1" |
| 79 |
|
| 80 |
All Xen-tools users should upgrade to the latest version: |
| 81 |
|
| 82 |
# emerge --sync |
| 83 |
# emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.2.2-r3" |
| 84 |
|
| 85 |
All Xen-pvgrub users should upgrade to the latest version: |
| 86 |
|
| 87 |
# emerge --sync |
| 88 |
# emerge --ask --oneshot -v ">=app-emulation/xen-pvgrub-4.2.2-r1" |
