========================================================================== Ubuntu Security Notice USN-3631-1 April 24, 2018
linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-kvm: Linux kernel for cloud environments - linux-raspi2: Linux kernel for Raspberry Pi 2 - linux-snapdragon: Linux kernel for Snapdragon processors
Details:
It was discovered that a buffer overread vulnerability existed in the keyring subsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2017-13305)
It was discovered that the DM04/QQBOX USB driver in the Linux kernel did not properly handle device attachment and warm-start. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16538)
Luo Quan and Wei Yang discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system deadlock). (CVE-2018-1000004)
Wang Qize discovered that an information disclosure vulnerability existed in the SMBus driver for ACPI Embedded Controllers in the Linux kernel. A local attacker could use this to expose sensitive information (kernel pointer addresses). (CVE-2018-5750)
èéŸé£ discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel that could lead to a use-after-free or an out-of-bounds buffer access. A local attacker with access to /dev/snd/seq could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-7566)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.4.0-1021-kvm 4.4.0-1021.26 linux-image-4.4.0-1055-aws 4.4.0-1055.64 linux-image-4.4.0-1087-raspi2 4.4.0-1087.95 linux-image-4.4.0-1090-snapdragon 4.4.0-1090.95 linux-image-4.4.0-121-generic 4.4.0-121.145 linux-image-4.4.0-121-generic-lpae 4.4.0-121.145 linux-image-4.4.0-121-lowlatency 4.4.0-121.145 linux-image-4.4.0-121-powerpc-e500mc 4.4.0-121.145 linux-image-4.4.0-121-powerpc-smp 4.4.0-121.145 linux-image-4.4.0-121-powerpc64-emb 4.4.0-121.145 linux-image-4.4.0-121-powerpc64-smp 4.4.0-121.145 linux-image-aws 4.4.0.1055.57 linux-image-generic 4.4.0.121.127 linux-image-generic-lpae 4.4.0.121.127 linux-image-kvm 4.4.0.1021.20 linux-image-lowlatency 4.4.0.121.127 linux-image-powerpc-e500mc 4.4.0.121.127 linux-image-powerpc-smp 4.4.0.121.127 linux-image-powerpc64-emb 4.4.0.121.127 linux-image-powerpc64-smp 4.4.0.121.127 linux-image-raspi2 4.4.0.1087.87 linux-image-snapdragon 4.4.0.1090.82
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.
