Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the version of the libcacard package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - Memory leak in the vcard_apdu_new function in     card_7816.c in libcacard before 2.5.3 allows local     guest OS users to cause a denial of service (host     memory consumption) via vectors related to allocating a     new APDU object.(CVE-2017-6414)

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

  - A malicious 64-bit PV guest may be able to access all of     system memory, allowing for all of privilege escalation,     host crashes, and information leaks by placing a IRET     hypercall in the middle of a multicall batch (XSA-213,     bsc#1034843)

  - A malicious pair of guests may be able to access all of     system memory, allowing for all of privilege escalation,     host crashes, and information leaks because of a missing     check when transfering pages via GNTTABOP_transfer     (XSA-214, bsc#1034844).

  - CVE-2017-7718: hw/display/cirrus_vga_rop.h allowed local     guest OS privileged users to cause a denial of service     (out-of-bounds read and QEMU process crash) via vectors     related to copying VGA data via the     cirrus_bitblt_rop_fwd_transp_ and cirrus_bitblt_rop_fwd_     functions (bsc#1034994).

  - CVE-2016-9603: A privileged user within the guest VM     could have caused a heap overflow in the device model     process, potentially escalating their privileges to that     of the device model process (bsc#1028655)

The update package also includes non-security fixes. See advisory for details.

This update for xen fixes the following security issues :

  - CVE-2017-7228: Broken check in memory_exchange()     permited PV guest breakout (bsc#1030442).

  - CVE-2017-6414: Memory leak in the vcard_apdu_new     function in card_7816.c in libcacard allowed local guest     OS users to cause a denial of service (host memory     consumption) via vectors related to allocating a new     APDU object (bsc#1027570).

  - CVE-2017-6505: The ohci_service_ed_list function in     hw/usb/hcd-ohci.c allowed local guest OS users to cause     a denial of service (infinite loop) via vectors     involving the number of link endpoint list descriptors     (bsc#1028235).
