TITLE

Xen of __addr_ok Service disruption in macro (DoS) Vulnerabilities

DESCRIPTION

Off-by-one error in the __addr_ok macro in Xen 3.3 and earlier allows local 64 bit PV guest administrators to cause a denial of service (host crash) via unspecified hypercalls that ignore virtual-address bits. Xen is prone to a denial-of-service vulnerability due to an off-by-one error. An attacker with access to a guest operating system can exploit this issue to crash the host operating system, effectively denying service to legitimate users. Due to the nature of this issue arbitrary code-execution maybe possible; however this has not been confirmed,. Hitachi JP1 products are prone to a cross-site scripting vulnerability because they fail to properly sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks. The following products are affected: JP1/IT Resource Management - Manager JP1/IT Service Level Management - Manager. This update also fixes several bugs. Documentation for these bug fixes will be available shortly from the Technical Notes document linked to in the References section. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Relevant releases/architectures: Red Hat Enterprise Linux EUS (v. 5.6 server) - i386, ia64, noarch, ppc, s390x, x86_64 3. Description: These packages contain the Linux kernel. This update fixes the following security issues: * A flaw in the Stream Control Transmission Protocol (SCTP) implementation could allow a remote attacker to cause a denial of service by sending a specially-crafted SCTP packet to a target system. (CVE-2011-2482, Important) If you do not run applications that use SCTP, you can prevent the sctp module from being loaded by adding the following to the end of the "/etc/modprobe.d/blacklist.conf" file: blacklist sctp This way, the sctp module cannot be loaded accidentally, which may occur if an application that requires SCTP is started. A reboot is not necessary for this change to take effect. * A flaw in the client-side NFS Lock Manager (NLM) implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2491, Important) * Flaws in the netlink-based wireless configuration interface could allow a local user, who has the CAP_NET_ADMIN capability, to cause a denial of service or escalate their privileges on systems that have an active wireless interface. (CVE-2011-2517, Important) * A flaw was found in the way the Linux kernel's Xen hypervisor implementation emulated the SAHF instruction. When using a fully-virtualized guest on a host that does not use hardware assisted paging (HAP), such as those running CPUs that do not have support for (or those that have it disabled) Intel Extended Page Tables (EPT) or AMD Virtualization (AMD-V) Rapid Virtualization Indexing (RVI), a privileged guest user could trigger this flaw to cause the hypervisor to crash. (CVE-2011-2519, Moderate) * A flaw in the __addr_ok() macro in the Linux kernel's Xen hypervisor implementation when running on 64-bit systems could allow a privileged guest user to crash the hypervisor. (CVE-2011-2901, Moderate) * /proc/[PID]/io is world-readable by default. Previously, these files could be read without any further restrictions. A local, unprivileged user could read these files, belonging to other, possibly privileged processes to gather confidential information, such as the length of a password used in a process. (CVE-2011-2495, Low) Red Hat would like to thank Vasily Averin for reporting CVE-2011-2491, and Vasiliy Kulikov of Openwall for reporting CVE-2011-2495. This update also fixes the following bugs: * On Broadcom PCI cards that use the tg3 driver, the operational state of a network device, represented by the value in "/sys/class/net/ethX/operstate", was not initialized by default. Consequently, the state was reported as "unknown" when the tg3 network device was actually in the "up" state. This update modifies the tg3 driver to properly set the operstate value. (BZ#744699) * A KVM (Kernel-based Virtual Machine) guest can get preempted by the host, when a higher priority process needs to run. When a guest is not running for several timer interrupts in a row, ticks could be lost, resulting in the jiffies timer advancing slower than expected and timeouts taking longer than expected. To correct for the issue of lost ticks, do_timer_tsc_timekeeping() checks a reference clock source (kvm-clock when running as a KVM guest) to see if timer interrupts have been missed. If so, jiffies is incremented by the number of missed timer interrupts, ensuring that programs are woken up on time. (BZ#747874) * When a block device object was allocated, the bd_super field was not being explicitly initialized to NULL. Previously, users of the block device object could set bd_super to NULL when the object was released by calling the kill_block_super() function. Certain third-party file systems do not always use this function, and bd_super could therefore become uninitialized when the object was allocated again. This could cause a kernel panic in the blkdev_releasepage() function, when the uninitialized bd_super field was dereferenced. Now, bd_super is properly initialized in the bdget() function, and the kernel panic no longer occurs. (BZ#751137) 4. Solution: Users should upgrade to these updated packages, which contain backported patches to resolve these issues. The system must be rebooted for this update to take effect. Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.

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/msg00006.h= tml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201309-24.xml Concerns?
