Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Information disclosure
EUVDB-ID: #VU9883
Risk: Low
CVSSv3.1: 5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-5715
CWE-ID:
CWE-200 - Information exposure
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists in Intel CPU hardware due to improper implementation of the speculative execution of instructions. A local attacker can utilize branch target injection, execute arbitrary code, perform a side-channel attack and read sensitive memory information.
MitigationUpdate the affected packages.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Resource exhaustion
EUVDB-ID: #VU11450
Risk: Low
CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1064
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists in the qemu_agent.c source code file due to an incomplete fix for CVE-2018-5748 that affects the QEMU monitor. A local attacker can consume excessive amounts of memory resources and cause the service to crash.
MitigationUpdate the affected packages.

3) Resource exhaustion
EUVDB-ID: #VU11465
Risk: Low
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-5748
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to a flaw in qemu/qemu_monitor.c in libvirt. A remote attacker can supply a large QEMU reply, trigger resource exhaustion and cause the service to crash.
Update the affected packages.
