Background ========== Xen is a bare-metal hypervisor. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-emulation/xen < 4.2.2-r1 >= 4.2.2-r1 2 app-emulation/xen-tools < 4.2.2-r3 >= 4.2.2-r3 3 app-emulation/xen-pvgrub < 4.2.2-r1 >= 4.2.2-r1 ------------------------------------------------------------------- 3 affected packages Description =========== Multiple vulnerabilities have been discovered in Xen. Please review the CVE identifiers referenced below for details. Impact ====== Guest domains could possibly gain privileges, execute arbitrary code, or cause a Denial of Service on the host domain (Dom0). Additionally, guest domains could gain information about other virtual machines running on the same host or read arbitrary files on the host. Workaround ========== The CVEs listed below do not currently have fixes, but only apply to Xen setups which have "tmem" specified on the hypervisor command line. TMEM is not currently supported for use in production systems, and administrators using tmem should disable it. Relevant CVEs: * CVE-2012-2497 * CVE-2012-6030 * CVE-2012-6031 * CVE-2012-6032 * CVE-2012-6033 * CVE-2012-6034 * CVE-2012-6035 * CVE-2012-6036 Resolution ========== All Xen users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-emulation/xen-4.2.2-r1" All Xen-tools users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.2.2-r3" All Xen-pvgrub users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot -v ">=app-emulation/xen-pvgrub-4.2.2-r1" References ========== [ 1 ] CVE-2011-2901 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-2901 [ 2 ] CVE-2011-3262 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3262 [ 3 ] CVE-2011-3262 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-3262 [ 4 ] CVE-2012-0217 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0217 [ 5 ] CVE-2012-0218 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-0218 [ 6 ] CVE-2012-2934 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-2934 [ 7 ] CVE-2012-3432 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3432 [ 8 ] CVE-2012-3433 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3433 [ 9 ] CVE-2012-3494 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3494 [ 10 ] CVE-2012-3495 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3495 [ 11 ] CVE-2012-3496 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3496 [ 12 ] CVE-2012-3497 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3497 [ 13 ] CVE-2012-3498 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3498 [ 14 ] CVE-2012-3515 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-3515 [ 15 ] CVE-2012-4411 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-4411 [ 16 ] CVE-2012-4535 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-4535 [ 17 ] CVE-2012-4536 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-4536 [ 18 ] CVE-2012-4537 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-4537 [ 19 ] CVE-2012-4538 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-4538 [ 20 ] CVE-2012-4539 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-4539 [ 21 ] CVE-2012-5510 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5510 [ 22 ] CVE-2012-5511 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5511 [ 23 ] CVE-2012-5512 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5512 [ 24 ] CVE-2012-5513 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5513 [ 25 ] CVE-2012-5514 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5514 [ 26 ] CVE-2012-5515 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5515 [ 27 ] CVE-2012-5525 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5525 [ 28 ] CVE-2012-5634 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5634 [ 29 ] CVE-2012-6030 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6030 [ 30 ] CVE-2012-6031 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6031 [ 31 ] CVE-2012-6032 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6032 [ 32 ] CVE-2012-6033 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6033 [ 33 ] CVE-2012-6034 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6034 [ 34 ] CVE-2012-6035 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6035 [ 35 ] CVE-2012-6036 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6036 [ 36 ] CVE-2012-6075 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6075 [ 37 ] CVE-2012-6333 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6333 [ 38 ] CVE-2013-0151 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0151 [ 39 ] CVE-2013-0152 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0152 [ 40 ] CVE-2013-0153 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0153 [ 41 ] CVE-2013-0154 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0154 [ 42 ] CVE-2013-0215 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0215 [ 43 ] CVE-2013-1432 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1432 [ 44 ] CVE-2013-1917 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1917 [ 45 ] CVE-2013-1918 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1918 [ 46 ] CVE-2013-1919 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1919 [ 47 ] CVE-2013-1920 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1920 [ 48 ] CVE-2013-1922 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1922 [ 49 ] CVE-2013-1952 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1952 [ 50 ] CVE-2013-1964 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-1964 [ 51 ] CVE-2013-2076 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2076 [ 52 ] CVE-2013-2077 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2077 [ 53 ] CVE-2013-2078 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2078 [ 54 ] CVE-2013-2194 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2194 [ 55 ] CVE-2013-2195 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2195 [ 56 ] CVE-2013-2196 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2196 [ 57 ] CVE-2013-2211 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-2211 [ 58 ] Xen TMEM http://lists.xen.org/archives/html/xen-announce/2012-09/m...
