linux, linux-azure, linux-gcp, linux-gke-5.0, linux-hwe, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in the Linux kernel.
Software Description
Amit Klein and Benny Pinkas discovered that the Linux kernel did not sufficiently randomize IP ID values generated for connectionless networking protocols. A remote attacker could use this to track particular Linux devices. (CVE-2019-10638)
Praveen Pandey discovered that the Linux kernel did not properly validate sent signals in some situations on PowerPC systems with transactional memory disabled. A local attacker could use this to cause a denial of service. (CVE-2019-13648)
It was discovered that the floppy driver in the Linux kernel did not properly validate meta data, leading to a buffer overread. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-14283)
It was discovered that the floppy driver in the Linux kernel did not properly validate ioctl() calls, leading to a division-by-zero. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-14284)
Jason Wang discovered that an infinite loop vulnerability existed in the virtio net driver in the Linux kernel. A local attacker in a guest VM could possibly use this to cause a denial of service in the host system. (CVE-2019-3900)
Update instructions

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
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.
