Detailsinfo

A vulnerability was found in Linux Foundation Xen (Virtualization Software). It has been rated as problematic. Affected by this issue is the function XEN_DOMCTL_getmemlist. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is availability. CVE summarizes:

The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock).

The weakness was published 11/26/2013 by Andrew Cooper with Coverity Scan as Xen Security Advisory 74 - Lock order reversal between page_alloc_lock and mm_rwlock as confirmed mailinglist post (oss-sec). The advisory is available at seclists.org. The public release has been coordinated with the vendor. The mailinglist post contains:

The locks page_alloc_lock and mm_rwlock are not always taken in the same order. This raises the possibility of deadlock.The incorrect order occurs only in the implementation of the deprecated domctl hypercall XEN_DOMCTL_getmemlist.
This vulnerability is handled as CVE-2013-4553 since 06/12/2013. Local access is required to approach this attack. A simple authentication is needed for exploitation. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 71590 (Fedora 20 : xen-4.3.1-6.fc20 (2013-23251)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 166934 (OpenSuSE Security Update for xen (openSUSE-SU-2014:0482-1)).

The best possible mitigation is suggested to be Workaround. The mailinglist post contains the following remark:

If you are using a toolstack (or other software) which uses XEN_DOMCTL_getmemlist, disabling the relevant feature or functions may be possible, and would avoid the vulnerability.

The vulnerability is also documented in the databases at X-Force (89312), Tenable (71590), SecurityFocus (BID 63933†), OSVDB (100387†) and Vulnerability Center (SBV-42566†).
