Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-3798-1)

high Nessus Plugin ID 118329

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-3798-1 advisory.

 Dmitry Vyukov discovered that the key management subsystem in the Linux kernel did not properly restrict adding a key that already exists but is negatively instantiated. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2015-8539)

 It was discovered that a use-after-free vulnerability existed in the device driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-7913)

 Pengfei Ding (), Chenfu Bao (), and Lenx Wei () discovered a race condition in the generic SCSI driver (sg) of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-0794)

 Eric Biggers discovered that the key management subsystem in the Linux kernel did not properly restrict adding a key that already exists but is uninstantiated. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-15299)

 It was discovered that a NULL pointer dereference could be triggered in the OCFS2 file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-18216)

 Luo Quan and Wei Yang discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system deadlock). (CVE-2018-1000004)

 discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel that could lead to a use- after-free or an out-of-bounds buffer access. A local attacker with access to /dev/snd/seq could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-7566)

 It was discovered that a buffer overflow existed in the NFC Logical Link Control Protocol (llcp) implementation in the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-9518)

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.
