Ubuntu 18.04 LTS : Linux kernel vulnerabilities (USN-3847-1)

high Nessus Plugin ID 119827

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that a race condition existed in the raw MIDI driver for the Linux kernel, leading to a double free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10902)

It was discovered that an integer overrun vulnerability existed in the POSIX timers implementation in the Linux kernel. A local attacker could use this to cause a denial of service. (CVE-2018-12896)

Noam Rathaus discovered that a use-after-free vulnerability existed in the Infiniband implementation in the Linux kernel. An attacker could use this to cause a denial of service (system crash). (CVE-2018-14734)

It was discovered that the YUREX USB device driver for the Linux kernel did not properly restrict user space reads or writes. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2018-16276)

It was discovered that the BPF verifier in the Linux kernel did not correctly compute numeric bounds in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-18445)

Kanda Motohiro discovered that writing extended attributes to an XFS file system in the Linux kernel in certain situations could cause an error condition to occur. A local attacker could use this to cause a denial of service. (CVE-2018-18690)

It was discovered that an integer overflow vulnerability existed in the CDROM driver of the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-18710).

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.

Solution

Update the affected packages.
