Robert Święcki discovered that the Linux kernel did not properly apply
Address Space Layout Randomization (ASLR) in some situations for setuid elf
binaries. A local attacker could use this to improve the chances of
exploiting an existing vulnerability in a setuid elf binary.
(CVE-2019-11190)
It was discovered that a null pointer dereference vulnerability existed in
the LSI Logic MegaRAID driver in the Linux kernel. A local attacker could
use this to cause a denial of service (system crash). (CVE-2019-11810)
It was discovered that a race condition leading to a use-after-free existed
in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux
kernel. The RDS protocol is disabled via blocklist by default in Ubuntu.
If enabled, a local attacker could use this to cause a denial of service
system crash) or possibly execute arbitrary code. (CVE-2019-11815)
Federico Manuel Bento discovered that the Linux kernel did not properly
apply Address Space Layout Randomization (ASLR) in some situations for
setuid a.out binaries. A local attacker could use this to improve the
chances of exploiting an existing vulnerability in a setuid a.out binary.
(CVE-2019-11191)
As a hardening measure, this update disables a.out support.
