[USN-3641-2] Linux kernel vulnerabilities
Several security issues were fixed in the Linux kernel.
USN-3641-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04
LTS, Ubuntu 16.04 LTS, and Ubuntu 17.10. This update provides the
corresponding updates for Ubuntu 12.04 ESM.
Nick Peterson discovered that the Linux kernel did not properly handle
debug exceptions following a MOV/POP to SS instruction. A local attacker
could use this to cause a denial of service (system crash). This issue only
affected the amd64 architecture. (CVE-2018-8897)
Andy Lutomirski discovered that the KVM subsystem of the Linux kernel did
not properly emulate the ICEBP instruction following a MOV/POP to SS
instruction. A local attacker in a KVM virtual machine could use this to
cause a denial of service (guest VM crash) or possibly escalate privileges
inside of the virtual machine. This issue only affected the i386 and amd64
architectures. (CVE-2018-1087)
Andy Lutomirski discovered that the Linux kernel did not properly perform
error handling on virtualized debug registers. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2018-1000199)
