high Nessus Plugin ID 109315

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-3631-2 advisory.

 - A information disclosure vulnerability in the Upstream kernel encrypted-keys. Product: Android. Versions:
 Android kernel. Android ID: A-70526974. (CVE-2017-13305)

 - drivers/media/usb/dvb-usb-v2/lmedm04.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (general protection fault and system crash) or possibly have unspecified other impact via a crafted USB device, related to a missing warm-start check and incorrect attach timing (dm04_lme2510_frontend_attach versus dm04_lme2510_tuner). (CVE-2017-16538)

 - In the Linux kernel 4.12, 3.10, 2.6 and possibly earlier versions a race condition vulnerability exists in the sound system, this can lead to a deadlock and denial of service condition. (CVE-2018-1000004)

 - The acpi_smbus_hc_add function in drivers/acpi/sbshc.c in the Linux kernel through 4.14.15 allows local users to obtain sensitive address information by reading dmesg data from an SBS HC printk call.
 (CVE-2018-5750)

 - The Linux kernel 4.15 has a Buffer Overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user. (CVE-2018-7566)

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.
