Ubuntu 16.04 LTS : Linux kernel vulnerabilities (USN-4116-1)

high Nessus Plugin ID 128476

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-4116-1 advisory.

 It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-20856)

 Amit Klein and Benny Pinkas discovered that the Linux kernel did not sufficiently randomize IP ID values generated for connectionless networking protocols. A remote attacker could use this to track particular Linux devices. (CVE-2019-10638)

 Praveen Pandey discovered that the Linux kernel did not properly validate sent signals in some situations on PowerPC systems with transactional memory disabled. A local attacker could use this to cause a denial of service. (CVE-2019-13648)

 It was discovered that the floppy driver in the Linux kernel did not properly validate meta data, leading to a buffer overread. A local attacker could use this to cause a denial of service (system crash).
 (CVE-2019-14283)

 It was discovered that the floppy driver in the Linux kernel did not properly validate ioctl() calls, leading to a division-by-zero. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-14284)

 Jason Wang discovered that an infinite loop vulnerability existed in the virtio net driver in the Linux kernel. A local attacker in a guest VM could possibly use this to cause a denial of service in the host system. (CVE-2019-3900)

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.
