========================================================================== Ubuntu Security Notice USN-4211-1 December 03, 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:
Zhipeng Xie discovered that an infinite loop could be triggered in the CFS Linux kernel process scheduler. A local attacker could possibly use this to cause a denial of service. (CVE-2018-20784)
Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel did not properly validate SSID lengths. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-17133)
Nicolas Waisman discovered that the Chelsio T4/T5 RDMA Driver for the Linux kernel performed DMA from a kernel stack. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-17075)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.4.0-1063-kvm 4.4.0-1063.70 linux-image-4.4.0-1099-aws 4.4.0-1099.110 linux-image-4.4.0-1126-raspi2 4.4.0-1126.135 linux-image-4.4.0-1130-snapdragon 4.4.0-1130.138 linux-image-4.4.0-170-generic 4.4.0-170.199 linux-image-4.4.0-170-generic-lpae 4.4.0-170.199 linux-image-4.4.0-170-lowlatency 4.4.0-170.199 linux-image-4.4.0-170-powerpc-e500mc 4.4.0-170.199 linux-image-4.4.0-170-powerpc-smp 4.4.0-170.199 linux-image-4.4.0-170-powerpc64-emb 4.4.0-170.199 linux-image-4.4.0-170-powerpc64-smp 4.4.0-170.199 linux-image-aws 4.4.0.1099.103 linux-image-generic 4.4.0.170.178 linux-image-generic-lpae 4.4.0.170.178 linux-image-kvm 4.4.0.1063.63 linux-image-lowlatency 4.4.0.170.178 linux-image-powerpc-e500mc 4.4.0.170.178 linux-image-powerpc-smp 4.4.0.170.178 linux-image-powerpc64-emb 4.4.0.170.178 linux-image-powerpc64-smp 4.4.0.170.178 linux-image-raspi2 4.4.0.1126.126 linux-image-snapdragon 4.4.0.1130.122 linux-image-virtual 4.4.0.170.178
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.
