CVE-2017-6414

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.

These are all security issues fixed in the libcacard-devel-2.8.0-1.7 package on the GA media of openSUSE Tumbleweed.

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).

These security issues were fixed:

• CVE-2017-7228: Broken check in memory_exchange() permited PV guest breakout (bsc#1030442).
• XSA-206: Unprivileged guests issuing writes to xenstore were able to stall progress of the control domain or driver domain, possibly leading to a Denial of Service (DoS) of the entire host (bsc#1030144).
• 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).
• 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-2017-2633: The VNC display driver support was vulnerable to an out-of-bounds memory access issue. A user/process inside guest could use this flaw to cause DoS (bsc#1026636).
• CVE-2016-9603: A privileged user within the guest VM can cause a heap overflow in the device model process, potentially escalating their privileges to that of the device model process (bsc#1028655).

These non-security issues were fixed:

• bsc#1022555: Timeout in 'execution of /etc/xen/scripts/block add'
• bsc#1029827: Forward port xenstored

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)

These non-security issues were fixed:

• bsc#1027519: Missing upstream bug fixes
• bsc#1015348: libvirtd does not start during boot
• bsc#1022555: Timeout in 'execution of /etc/xen/scripts/block add
