Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU8424
Risk: Low
CVSSv3.1: 8.3 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-14316
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to execute arbitrary code on the host system.
The weakness exists due to out-of-bounds array access in the processing of NUMA node
parameters. An adjacent attacker can invoke specially crafted hypercalls and execute arbitrary code with elevated privileges.
Update the affected packages.
Xen: 4.5.0 - 4.9.0

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU8426
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-14317
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to cause DoS condition on the host system.
The weakness exists due to race condition in cxenstored. An adjacent attacker can shut down a virtual machine with a stubdomain, trigger a double-free memory error and cause the xenstored daemon to crash.
The vulnerability is exploitable on the systems running the C
version os xenstored ("xenstored") and running devicemodel stubdomains.
Update the affected packages.

EUVDB-ID: #VU8425
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-14318
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to gain elevated privileges or cause DoS condition on the host system.
The weakness exists due to NULL pointer deference in certain GNTTABOP_cache_flush grant table operations. If exploited on x86-based PV guest systems without SMAP enabled, an adjacent attacker can gain elevated privileges. If exploited on ARM-based guest systems and x86-based PV guest systems that have SMAP enabled, an adjacent attacker can cause the host system to crash.
Update the affected packages.

CVE-ID: CVE-2017-14319
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to gain elevated privileges or cause DoS condition on the host system.
The weakness exists due to a flaw in grant unmapping. A local attacker on
an x86 PV guest system can gain
elevated privileges on the host system or cause the hypervisor to crash.
Update the affected packages.
