========================================================================== Ubuntu Security Notice USN-4005-1 June 04, 2019
linux, linux-aws, linux-gcp, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 19.04
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-gcp: Linux kernel for Google Cloud Platform (GCP) 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 null pointer dereference vulnerability existed in the LSI Logic MegaRAID driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-11810)
It was discovered that a race condition leading to a use-after-free existed in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel. The RDS protocol is blacklisted by default in Ubuntu. If enabled, a local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-11815)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 19.04: linux-image-5.0.0-1007-aws 5.0.0-1007.7 linux-image-5.0.0-1007-gcp 5.0.0-1007.7 linux-image-5.0.0-1007-kvm 5.0.0-1007.7 linux-image-5.0.0-1009-raspi2 5.0.0-1009.9 linux-image-5.0.0-1013-snapdragon 5.0.0-1013.13 linux-image-5.0.0-16-generic 5.0.0-16.17 linux-image-5.0.0-16-generic-lpae 5.0.0-16.17 linux-image-5.0.0-16-lowlatency 5.0.0-16.17 linux-image-aws 5.0.0.1007.7 linux-image-gcp 5.0.0.1007.7 linux-image-generic 5.0.0.16.17 linux-image-generic-lpae 5.0.0.16.17 linux-image-gke 5.0.0.1007.7 linux-image-kvm 5.0.0.1007.7 linux-image-lowlatency 5.0.0.16.17 linux-image-raspi2 5.0.0.1009.6 linux-image-snapdragon 5.0.0.1013.6
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.
