========================================================================== Ubuntu Security Notice USN-3822-1 November 14, 2018
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux: Linux kernel
Details:
Jim Mattson discovered that the KVM implementation in the Linux kernel mismanages the #BP and #OF exceptions. A local attacker in a guest virtual machine could use this to cause a denial of service (guest OS crash). (CVE-2016-9588)
It was discovered that the generic SCSI driver in the Linux kernel did not properly enforce permissions on kernel memory access. A local attacker could use this to expose sensitive information or possibly elevate privileges. (CVE-2017-13168)
Andrey Konovalov discovered that the CDC USB Ethernet driver did not properly validate device descriptors. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-16649)
It was discovered that an integer overflow existed in the CD-ROM driver of the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-16658)
It was discovered that an integer overflow existed in the HID Bluetooth implementation in the Linux kernel that could lead to a buffer overwrite. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-9363)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-3.13.0-162-generic 3.13.0-162.212 linux-image-3.13.0-162-generic-lpae 3.13.0-162.212 linux-image-3.13.0-162-lowlatency 3.13.0-162.212 linux-image-3.13.0-162-powerpc-e500 3.13.0-162.212 linux-image-3.13.0-162-powerpc-e500mc 3.13.0-162.212 linux-image-3.13.0-162-powerpc-smp 3.13.0-162.212 linux-image-3.13.0-162-powerpc64-emb 3.13.0-162.212 linux-image-3.13.0-162-powerpc64-smp 3.13.0-162.212 linux-image-generic 3.13.0.162.172 linux-image-generic-lpae 3.13.0.162.172 linux-image-lowlatency 3.13.0.162.172 linux-image-powerpc-e500 3.13.0.162.172 linux-image-powerpc-e500mc 3.13.0.162.172 linux-image-powerpc-smp 3.13.0.162.172 linux-image-powerpc64-emb 3.13.0.162.172 linux-image-powerpc64-smp 3.13.0.162.172
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
