The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Qemu: net: ne2000: OOB memory access in ioport r/w functions (CVE-2015-8743)

  - The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of     service (host disk consumption) by writing to stdout or stderr. (CVE-2014-3672)

  - The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit     descriptor data when sending a network packet, which allows attackers to cause a denial of service     (infinite loop and guest crash) via unspecified vectors. (CVE-2015-6815)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Qemu: audio: host memory leakage via capture buffer (CVE-2017-8309)

  - The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of     service (host disk consumption) by writing to stdout or stderr. (CVE-2014-3672)

  - The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit     descriptor data when sending a network packet, which allows attackers to cause a denial of service     (infinite loop and guest crash) via unspecified vectors. (CVE-2015-6815)

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - xsa224 xen: grant table operations mishandle reference counts (XSA-224) (CVE-2017-10921)

  - The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of     service (host disk consumption) by writing to stdout or stderr. (CVE-2014-3672)

  - Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary     code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS     set. (CVE-2015-3209)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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

  - CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the     bitblit copy routine cirrus_bitblt_cputovideo failed to     check the memory region, allowing for an out-of-bounds     write that allows for privilege escalation     (bsc#1024834).

  - CVE-2017-2615: An error in the bitblt copy operation     could have allowed a malicious guest administrator to     cause an out of bounds memory access, possibly leading     to information disclosure or privilege escalation     (bsc#1023004).

  - A malicious guest could have, by frequently rebooting     over extended periods of time, run the host system out     of memory, resulting in a Denial of Service (DoS)     (bsc#1022871)

  - CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support     was vulnerable to a divide by zero issue while copying     VGA data. A privileged user inside guest could have used     this flaw to crash the process instance on the host,     resulting in DoS (bsc#1015169
