Ubuntu 16.04 LTS : Linux kernel vulnerabilities (USN-4228-1)

critical Nessus Plugin ID 132692

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4228-1 advisory.

 It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895, CVE-2019-14901)

 It was discovered that a heap-based buffer overflow existed in the Marvell Libertas WLAN Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14896, CVE-2019-14897)

 Anthony Steinhauser discovered that the Linux kernel did not properly perform Spectre_RSB mitigations to all processors for PowerPC architecture systems in some situations. A local attacker could use this to expose sensitive information. (CVE-2019-18660)

 It was discovered that Geschwister Schneider USB CAN interface driver in the Linux kernel did not properly deallocate memory in certain failure conditions. A physically proximate attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19052)

 It was discovered that the driver for memoryless force-feedback input devices in the Linux kernel contained a use-after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2019-19524)

 It was discovered that the PEAK-System Technik USB driver in the Linux kernel did not properly sanitize memory before sending it to the device. A physically proximate attacker could use this to expose sensitive information (kernel memory). (CVE-2019-19534)

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.
