Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-3698-1)

high Nessus Plugin ID 110900

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3698-1 advisory.

 It was discovered that the nested KVM implementation in the Linux kernel in some situations did not properly prevent second level guests from reading and writing the hardware CR8 register. A local attacker in a guest could use this to cause a denial of service (system crash). (CVE-2017-12154)

 Fan Wu, Haoran Qiu, and Shixiong Zhao discovered that the associative array implementation in the Linux kernel sometimes did not properly handle adding a new entry. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-12193)

 It was discovered that a race condition existed in the ALSA subsystem of the Linux kernel when creating and deleting a port via ioctl(). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15265)

 It was discovered that a null pointer dereference vulnerability existed in the DCCP protocol implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-1130)

 Julian Stecklina and Thomas Prescher discovered that FPU register states (such as MMX, SSE, and AVX registers) which are lazily restored are potentially vulnerable to a side channel attack. A local attacker could use this to expose sensitive information. (CVE-2018-3665)

 Wang Qize discovered that an information disclosure vulnerability existed in the SMBus driver for ACPI Embedded Controllers in the Linux kernel. A local attacker could use this to expose sensitive information (kernel pointer addresses). (CVE-2018-5750)

 It was discovered that the SCTP Protocol implementation in the Linux kernel did not properly validate userspace provided payload lengths in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-5803)

 It was discovered that an integer overflow error existed in the futex implementation in the Linux kernel.
 A local attacker could use this to cause a denial of service (system crash). (CVE-2018-6927)

 It was discovered that an information leak vulnerability existed in the floppy driver in the Linux kernel.
 A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-7755)

 It was discovered that a memory leak existed in the SAS driver subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2018-7757)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
