- CVEs with nessus.description==Jann Horn and Ken Johnson discovered that microprocessors utilizing speculative execution of a memory read may allow unauthorized memory reads via a sidechannel attack. This flaw is known as Spectre Variant 4. A local attacker could use this to expose sensitive information, including kernel memory. (CVE-2018-3639)
Jan H. Schonherr discovered that the Xen subsystem did not properly handle block IO merges correctly in some situations. An attacker in a guest vm could use this to cause a denial of service (host crash) or possibly gain administrative privileges in the host. (CVE-2017-12134)
It was discovered that the Bluetooth HIP Protocol implementation in the Linux kernel did not properly validate HID connection setup information. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-13220)
It was discovered that a buffer overread vulnerability existed in the keyring subsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information (kernel memory).
(CVE-2017-13305)
It was discovered that the netlink subsystem in the Linux kernel did not properly restrict observations of netlink messages to the appropriate net namespace. A local attacker could use this to expose sensitive information (kernel netlink traffic). (CVE-2017-17449)
It was discovered that a race condition existed in the i8042 serial device driver implementation in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-18079)
It was discovered that a race condition existed in the Device Mapper component of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-18203)
It was discovered that a race condition existed in the OCFS2 file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2017-18204)
It was discovered that an infinite loop could occur in the madvise(2) implementation in the Linux kernel in certain circumstances. A local attacker could use this to cause a denial of service (system hang).
(CVE-2017-18208)
Kefeng Wang discovered that a race condition existed in the memory locking implementation in the Linux kernel. A local attacker could use this to cause a denial of service. (CVE-2017-18221)
Silvio Cesare discovered a buffer overwrite existed in the NCPFS implementation in the Linux kernel. A remote attacker controlling a malicious NCPFS server could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-8822).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
