Multiple vulnerabilities have been discovered in the Xen hypervisor.
The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2016-7092 (XSA-185)     Jeremie Boutoille of Quarkslab and Shangcong Luan of     Alibaba discovered a flaw in the handling of L3     pagetable entries, allowing a malicious 32-bit PV guest     administrator can escalate their privilege to that of     the host.

  - CVE-2016-7094 (XSA-187)     x86 HVM guests running with shadow paging use a subset     of the x86 emulator to handle the guest writing to its     own pagetables. Andrew Cooper of Citrix discovered that     there are situations a guest can provoke which result in     exceeding the space allocated for internal state. A     malicious HVM guest administrator can cause Xen to fail     a bug check, causing a denial of service to the host.

  - CVE-2016-7154 (XSA-188)     Mikhail Gorobets of Advanced Threat Research, Intel     Security discovered a use after free flaw in the FIFO     event channel code. A malicious guest administrator can     crash the host, leading to a denial of service.
    Arbitrary code execution (and therefore privilege     escalation), and information leaks, cannot be excluded.

The Xen Project reports :

When the EVTCHNOP_init_control operation is called with a bad guest frame number, it takes an error path which frees a control structure without also clearing the corresponding pointer. Certain subsequent operations (EVTCHNOP_expand_array or another EVTCHNOP_init_control), upon finding the non-NULL pointer, continue operation assuming it points to allocated memory.

A malicious guest administrator can crash the host, leading to a DoS.
Arbitrary code execution (and therefore privilege escalation), and information leaks, cannot be excluded.

The remote OracleVM system is missing necessary patches to address critical security updates :

The version of Citrix XenServer running on the remote host is missing a security hotfix. It is, therefore, affected by multiple vulnerabilities :

  - A flaw exists due to improper handling of pagetable     walks that contain recursive L3 pagetable entries. An     attacker on the guest can exploit this to gain elevated     privileges. (CVE-2016-7092)

  - A flaw exists due to improper handling of instruction     pointer truncation when emulating HVM instructions. An     attacker on the guest can exploit this to gain elevated     privileges. (CVE-2016-7093)

  - An overflow condition exists in the x86 HVM guests due     to improper handling of writing to pagetables,     specifically when the guest is running shadow paging     using a subset of the x86 emulator. An attacker on the     guest can exploit this to cause a denial of service     condition on the host. (CVE-2016-7094)

  - A use-after-free error exists when calling the     EVTCHNOP_init_control operation with a bad guest frame     number. An attacker on the guest can exploit this, by     freeing a control structure without also clearing the     corresponding pointer, to crash the host or potentially     gain elevated privileges. (CVE-2016-7154)
