Citrix XenServer 7.1 and newer allows Directory Traversal.
2	CVE-2018-8897	362		2018-05-08	2019-10-03	7.2	None	Local	Low	Not required	Complete	Complete	Complete
A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs.
3	CVE-2018-3665	200	+Info	2018-06-21	2021-06-09	4.7	None	Local	Medium	Not required	Complete	None	None
System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially allow a local process to infer data from another process through a speculative execution side channel.
4	CVE-2017-12137	120	+Priv	2017-08-24	2019-10-03	7.2	None	Local	Low	Not required	Complete	Complete	Complete
arch/x86/mm.c in Xen allows local PV guest OS users to gain host OS privileges via vectors related to map_grant_ref.
5	CVE-2017-12136	362	DoS +Priv	2017-08-24	2019-05-06	6.9	None	Local	Medium	Not required	Complete	Complete	Complete
Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling.
6	CVE-2017-12135	682	DoS +Priv +Info	2017-08-24	2020-04-14	4.6	None	Local	Low	Not required	Partial	Partial	Partial
Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants.
7	CVE-2017-12134	682	DoS +Priv +Info	2017-08-24	2019-10-03	7.2	None	Local	Low	Not required	Complete	Complete	Complete
The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation.
8	CVE-2017-2620	125	Exec Code	2018-07-27	2021-08-04	9.0	None	Remote	Low	???	Complete	Complete	Complete
Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process.
9	CVE-2017-2615	125	Exec Code	2018-07-03	2021-08-04	9.0	None	Remote	Low	???	Complete	Complete	Complete
Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host.
10	CVE-2016-9603	119	Exec Code Overflow	2018-07-27	2021-08-04	9.0	None	Remote	Low	???	Complete	Complete	Complete
A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
