Ke Sun, Henrique Kawakami, Kekai Hu, Rodrigo Branco, Giorgi Maisuradze, Dan
Horea Lutas, Andrei Lutas, Volodymyr Pikhur, Stephan van Schaik, Alyssa
Milburn, Sebastian Österlund, Pietro Frigo, Kaveh Razavi, Herbert Bos,
Cristiano Giuffrida, Moritz Lipp, Michael Schwarz, and Daniel Gruss
discovered that memory previously stored in microarchitectural fill buffers
of an Intel CPU core may be exposed to a malicious process that is
executing on the same CPU core. A local attacker could use this to expose
sensitive information. (CVE-2018-12130)

Brandon Falk, Ke Sun, Henrique Kawakami, Kekai Hu, Rodrigo Branco, Stephan
van Schaik, Alyssa Milburn, Sebastian Österlund, Pietro Frigo, Kaveh
Razavi, Herbert Bos, and Cristiano Giuffrida discovered that memory
previously stored in microarchitectural load ports of an Intel CPU core may
be exposed to a malicious process that is executing on the same CPU core. A
local attacker could use this to expose sensitive information.
(CVE-2018-12127)

Ke Sun, Henrique Kawakami, Kekai Hu, Rodrigo Branco, Marina Minkin, Daniel
Moghimi, Moritz Lipp, Michael Schwarz, Jo Van Bulck, Daniel Genkin, Daniel
Gruss, Berk Sunar, Frank Piessens, and Yuval Yarom discovered that memory
previously stored in microarchitectural store buffers of an Intel CPU core
may be exposed to a malicious process that is executing on the same CPU
core. A local attacker could use this to expose sensitive information.
(CVE-2018-12126)

Kurtis Miller discovered that a buffer overflow existed in QEMU when
loading a device tree blob. A local attacker could use this to execute
arbitrary code. (CVE-2018-20815)

Ke Sun, Henrique Kawakami, Kekai Hu, Rodrigo Branco, Volodrmyr Pikhur,
Moritz Lipp, Michael Schwarz, Daniel Gruss, Stephan van Schaik, Alyssa
Milburn, Sebastian Österlund, Pietro Frigo, Kaveh Razavi, Herbert Bos, and
Cristiano Giuffrida discovered that uncacheable memory previously stored in
microarchitectural buffers of an Intel CPU core may be exposed to a
malicious process that is executing on the same CPU core. A local attacker
could use this to expose sensitive information. (CVE-2019-11091)

It was discovered that a NULL pointer dereference existed in the sun4u
power device implementation in QEMU. A local attacker could use this
to cause a denial of service. This issue only affected Ubuntu 18.10
and Ubuntu 19.04. (CVE-2019-5008)

William Bowling discovered that an information leak existed in the SLiRP
networking implementation of QEMU. An attacker could use this to expose
sensitive information. (CVE-2019-9824)
