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) - An unprivileged guest user was able to crash the guest. (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) - A privileged guest user could cause a crash of the emulator process on the host by exploiting a divide by zero vulnerability of the JAZZ RC4030 chipset emulation (boo#1005004 CVE-2016-8667) - A privileged guest user could cause a crash of the emulator process on the host by exploiting a divide by zero issue of the 16550A UART emulation (boo#1005005, CVE-2016-8669) - A privileged guest user could cause a memory leak in the USB EHCI emulation, causing a DoS situation on the host (boo#1003870, CVE-2016-7995) - A privileged guest user could cause an infinite loop in the USB xHCI emulation, causing a DoS situation on the host (boo#1004016, CVE-2016-8576) - A privileged guest user could cause an infinite loop in the ColdFire Fash Ethernet Controller emulation, causing a DoS situation on the host (boo#1003030, CVE-2016-7908) - A privileged guest user could cause an infinite loop in the AMD PC-Net II emulation, causing a DoS situation on the host (boo#1003032, CVE-2016-7909) - Cause a reload of clvm in the block-dmmd script to avoid a blocking lvchange call (boo#1002496) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
