Summary

oxenstored in Xen 4.1.x, Xen 4.2.x, and xen-unstable does not properly consider the state of the Xenstore ring during read operations, which allows guest OS users to cause a denial of service (daemon crash and host-control outage, or memory consumption) or obtain sensitive control-plane data by leveraging guest administrative access.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.

"The remote host is affected by the vulnerability described in GLSA-201309-24
(Xen: Multiple vulnerabilities)

    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 &ldquo;tmem&rdquo; 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

    Anderson (CVE-2013-0215)

  - ACPI: acpi_table_parse should return handler's error
    code Currently, the error code returned by
    acpi_table_parse's handler is ignored. This patch will
    propagate handler's return value to acpi_table_parse's
    caller. AMD,IOMMU: Clean up old entries in remapping
    tables when creating new interrupt mapping. When
    changing the affinity of an IRQ associated with a passed
    through PCI device, clear previous mapping. In addition,
    because some BIOSes may incorrectly program IVRS entries
    for IOAPIC try to check for entry's consistency.
    Specifically, if conflicting entries are found disable
    IOMMU if per-device remapping table is used. If entries
    refer to bogus IOAPIC IDs disable IOMMU unconditionally
    AMD,IOMMU: Disable IOMMU if SATA Combined mode is on
    AMD's SP5100 chipset can be placed into SATA Combined
    mode that may cause prevent dom0 from booting when IOMMU
    is enabled and per-device interrupt remapping table is
    used. While SP5100 erratum 28 requires BIOSes to disable
    this mode, some may still use it. This patch checks
    whether this mode is on and, if per-device table is in
    use, disables IOMMU. AMD,IOMMU: Make per-device
    interrupt remapping table default Using global interrupt
    remapping table may be insecure, as described by XSA-36.
    This patch makes per-device mode default. This is XSA-36

  - ACPI: acpi_table_parse should return handler's error
    code Currently, the error code returned by
    acpi_table_parse's handler is ignored. This patch will
    propagate handler's return value to acpi_table_parse's
    caller. AMD,IOMMU: Clean up old entries in remapping
    tables when creating new interrupt mapping. When
    changing the affinity of an IRQ associated with a passed
    through PCI device, clear previous mapping. In addition,
    because some BIOSes may incorrectly program IVRS entries
    for IOAPIC try to check for entry's consistency.
    Specifically, if conflicting entries are found disable
    IOMMU if per-device remapping table is used. If entries
    refer to bogus IOAPIC IDs disable IOMMU unconditionally
    AMD,IOMMU: Disable IOMMU if SATA Combined mode is on
    AMD's SP5100 chipset can be placed into SATA Combined
    mode that may cause prevent dom0 from booting when IOMMU
    is enabled and per-device interrupt remapping table is
    used. While SP5100 erratum 28 requires BIOSes to disable
    this mode, some may still use it. This patch checks
    whether this mode is on and, if per-device table is in
    use, disables IOMMU. AMD,IOMMU: Make per-device
    interrupt remapping table default Using global interrupt
    remapping table may be insecure, as described by XSA-36.
    This patch makes per-device mode default. This is XSA-36
    / CVE-2013-0153. (CVE-2013-0153)"
