Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This updates xen to version 4.5.5 to fix the following issues :

  - An unprivileged user in a guest could gain guest could     escalate privilege to that of the guest kernel, if it     had could invoke the instruction emulator. Only 64-bit     x86 HVM guest were affected. Linux guest have not been     vulnerable. (boo#1016340, CVE-2016-10013)

  - An unprivileged user in a 64 bit x86 guest could gain     information from the host, crash the host or gain     privilege of the host (boo#1009107, CVE-2016-9383)

  - An unprivileged guest process could (unintentionally or     maliciously) obtain or ocorrupt sensitive information of     other programs in the same guest. Only x86 HVM guests     have been affected. The attacker needs to be able to     trigger the Xen instruction emulator. (boo#1000106,     CVE-2016-7777)

  - A guest on x86 systems could read small parts of     hypervisor stack data (boo#1012651, CVE-2016-9932)

  - A malicious guest kernel could hang or crash the host     system (boo#1014298, CVE-2016-10024)

  - The epro100 emulated network device caused a memory leak     in the host when unplugged in the guest. A privileged     user in the guest could use this to cause a DoS on the     host or potentially crash the guest process on the host     (boo#1013668, CVE-2016-9101)

  - The ColdFire Fast Ethernet Controller was vulnerable to     an infinite loop that could be trigged by a privileged     user in the guest, leading to DoS (boo#1013657,     CVE-2016-9776)

  - A malicious guest administrator could escalate their     privilege to that of the host. Only affects x86 HVM     guests using qemu older version 1.6.0 or using the     qemu-xen-traditional. (boo#1011652, CVE-2016-9637)

  - An unprivileged guest user could escalate privilege to     that of the guest administrator on x86 HVM guests,     especially on Intel CPUs (boo#1009100, CVE-2016-9386)

  - An unprivileged guest user could escalate privilege to     that of the guest administrator (on AMD CPUs) or crash     the system (on Intel CPUs) on 32-bit x86 HVM guests.
    Only guest operating systems that allowed a new task to     start in VM86 mode were affected. (boo#1009103,     CVE-2016-9382)

  - A malicious guest administrator could crash the host on     x86 PV guests only (boo#1009104, CVE-2016-9385)

    (boo#1009108, CVE-2016-9377, CVE-2016-9378)

  - A malicious guest administrator could get privilege of     the host emulator process on x86 HVM guests.
    (boo#1009109, CVE-2016-9381)

  - A vulnerability in pygrub allowed a malicious guest     administrator to obtain the contents of sensitive host     files, or even delete those files (boo#1009111,     CVE-2016-9379, CVE-2016-9380)

  - A privileged guest user could cause an infinite loop in     the RTL8139 ethernet emulation to consume CPU cycles on     the host, causing a DoS situation (boo#1007157,     CVE-2016-8910)

  - A privileged guest user could cause an infinite loop in     the intel-hda sound emulation to consume CPU cycles on     the host, causing a DoS situation (boo#1007160,     CVE-2016-8909)

This update for xen to version 4.5.5 fixes several issues. These security issues were fixed :

  - CVE-2016-9637: ioport array overflow allowing a     malicious guest administrator can escalate their     privilege to that of the host (bsc#1011652)

  - CVE-2016-9386: x86 null segments were not always treated     as unusable allowing an unprivileged guest user program     to elevate its privilege to that of the guest operating     system. Exploit of this vulnerability is easy on Intel     and more complicated on AMD (bsc#1009100)

  - CVE-2016-9382: x86 task switch to VM86 mode was     mis-handled, allowing a unprivileged guest process to     escalate its privilege to that of the guest operating     system on AMD hardware. On Intel hardware a malicious     unprivileged guest process can crash the guest     (bsc#1009103)

  - CVE-2016-9385: x86 segment base write emulation lacked     canonical address checks, allowing a malicious guest     administrator to crash the host (bsc#1009104)

  - CVE-2016-9383: The x86 64-bit bit test instruction     emulation was broken, allowing a guest to modify     arbitrary memory leading to arbitray code execution     (bsc#1009107)

  - CVE-2016-9378: x86 software interrupt injection was     mis-handled, allowing an unprivileged guest user to     crash the guest (bsc#1009108)

  - CVE-2016-9377: x86 software interrupt injection was     mis-handled, allowing an unprivileged guest user to     crash the guest (bsc#1009108)

  - CVE-2016-9381: Improper processing of shared rings     allowing guest administrators take over the qemu     process, elevating their privilege to that of the qemu     process (bsc#1009109)

  - CVE-2016-9380: Delimiter injection vulnerabilities in     pygrub allowed guest administrators to obtain the     contents of sensitive host files or delete the files     (bsc#1009111)

  - CVE-2016-9379: Delimiter injection vulnerabilities in     pygrub allowed guest administrators to obtain the     contents of sensitive host files or delete the files     (bsc#1009111)

  - CVE-2016-7777: Xen did not properly honor CR0.TS and     CR0.EM, which allowed local x86 HVM guest OS users to     read or modify FPU, MMX, or XMM register state     information belonging to arbitrary tasks on the guest by     modifying an instruction while the hypervisor is     preparing to emulate it (bsc#1000106)

  - CVE-2016-8910: The rtl8139_cplus_transmit function in     hw/net/rtl8139.c allowed local guest OS administrators     to cause a denial of service (infinite loop and CPU     consumption) by leveraging failure to limit the ring     descriptor count (bsc#1007157)

  - CVE-2016-8909: The intel_hda_xfer function in     hw/audio/intel-hda.c allowed local guest OS     administrators to cause a denial of service (infinite     loop and CPU consumption) via an entry with the same     value for buffer length and pointer position     (bsc#1007160).

  - CVE-2016-8667: The rc4030_write function in     hw/dma/rc4030.c in allowed local guest OS administrators     to cause a denial of service (divide-by-zero error and     QEMU process crash) via a large interval timer reload     value (bsc#1005004)

  - CVE-2016-8669: The serial_update_parameters function in     hw/char/serial.c allowed local guest OS administrators     to cause a denial of service (divide-by-zero error and     QEMU process crash) via vectors involving a value of     divider greater than baud base (bsc#1005005)

  - CVE-2016-7995: A memory leak in ehci_process_itd allowed     a privileged user inside guest to DoS the host     (bsc#1003870).

  - CVE-2016-8576: The xhci_ring_fetch function in     hw/usb/hcd-xhci.c allowed local guest OS administrators     to cause a denial of service (infinite loop and QEMU     process crash) by leveraging failure to limit the number     of link Transfer Request Blocks (TRB) to process     (bsc#1004016).

  - CVE-2016-7908: The mcf_fec_do_tx function in     hw/net/mcf_fec.c did not properly limit the buffer     descriptor count when transmitting packets, which     allowed local guest OS administrators to cause a denial     of service (infinite loop and QEMU process crash) via     vectors involving a buffer descriptor with a length of 0     and crafted values in bd.flags (bsc#1003030)

  - CVE-2016-7909: The pcnet_rdra_addr function in     hw/net/pcnet.c allowed local guest OS administrators to     cause a denial of service (infinite loop and QEMU     process crash) by setting the (1) receive or (2)     transmit descriptor ring length to 0 (bsc#1003032)
