========================================================================== Ubuntu Security Notice USN-3910-1 March 15, 2019
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 the f2fs filesystem implementation in the Linux kernel did not handle the noflush_merge mount option correctly. An attacker could use this to cause a denial of service (system crash). (CVE-2017-18241)
It was discovered that the procfs filesystem did not properly handle processes mapping some memory elements onto files. A local attacker could use this to block utilities that examine the procfs filesystem to report operating system state, such as ps(1). (CVE-2018-1120)
Hui Peng and Mathias Payer discovered that the Option USB High Speed driver in the Linux kernel did not properly validate metadata received from the device. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2018-19985)
It was discovered that multiple integer overflows existed in the hugetlbfs implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-7740)
Jann Horn discovered a race condition in the fork() system call in the Linux kernel. A local attacker could use this to gain access to services that cache authorizations. (CVE-2019-6133)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.4.0-1041-kvm 4.4.0-1041.47 linux-image-4.4.0-1077-aws 4.4.0-1077.87 linux-image-4.4.0-1104-raspi2 4.4.0-1104.112 linux-image-4.4.0-1108-snapdragon 4.4.0-1108.113 linux-image-4.4.0-143-generic 4.4.0-143.169 linux-image-4.4.0-143-generic-lpae 4.4.0-143.169 linux-image-4.4.0-143-lowlatency 4.4.0-143.169 linux-image-4.4.0-143-powerpc-e500mc 4.4.0-143.169 linux-image-4.4.0-143-powerpc-smp 4.4.0-143.169 linux-image-4.4.0-143-powerpc64-emb 4.4.0-143.169 linux-image-4.4.0-143-powerpc64-smp 4.4.0-143.169 linux-image-aws 4.4.0.1077.80 linux-image-generic 4.4.0.143.151 linux-image-generic-lpae 4.4.0.143.151 linux-image-kvm 4.4.0.1041.41 linux-image-lowlatency 4.4.0.143.151 linux-image-powerpc-e500mc 4.4.0.143.151 linux-image-powerpc-smp 4.4.0.143.151 linux-image-powerpc64-emb 4.4.0.143.151 linux-image-powerpc64-smp 4.4.0.143.151 linux-image-raspi2 4.4.0.1104.104 linux-image-snapdragon 4.4.0.1108.100 linux-image-virtual 4.4.0.143.151
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.
