--===============0253364217831384640== Content-Type: multipart/signed; micalg=pgp-sha512; protocol="application/pgp-signature"; boundary="YToU2i3Vx8H2dn7O" Content-Disposition: inline --YToU2i3Vx8H2dn7O Content-Type: text/plain; charset=us-ascii Content-Disposition: inline ========================================================================== Ubuntu Security Notice USN-4076-1 July 25, 2019 linux, linux-aws, linux-kvm, linux-raspi2 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 Details: It was discovered that a race condition existed in the Serial Attached SCSI (SAS) implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2018-20836) It was discovered that the ext4 file system implementation in the Linux kernel did not properly zero out memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-11833) It was discovered that the Bluetooth Human Interface Device Protocol (HIDP) implementation in the Linux kernel did not properly verify strings were NULL terminated in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-11884) It was discovered that the Linux kernel on ARM processors allowed a tracing process to modify a syscall after a seccomp decision had been made on that syscall. A local attacker could possibly use this to bypass seccomp restrictions. (CVE-2019-2054) Hugues Anguelkov discovered that the Broadcom Wifi driver in the Linux kernel did not properly prevent remote firmware events from being processed for USB Wifi devices. A physically proximate attacker could use this to send firmware events to the device. (CVE-2019-9503) It was discovered that an integer overflow existed in the Freescale (PowerPC) hypervisor manager in the Linux kernel. A local attacker with write access to /dev/fsl-hv could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-10142) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.4.0-1052-kvm 4.4.0-1052.59 linux-image-4.4.0-1088-aws 4.4.0-1088.99 linux-image-4.4.0-1117-raspi2 4.4.0-1117.126 linux-image-4.4.0-157-generic 4.4.0-157.185 linux-image-4.4.0-157-generic-lpae 4.4.0-157.185 linux-image-4.4.0-157-lowlatency 4.4.0-157.185 linux-image-4.4.0-157-powerpc-e500mc 4.4.0-157.185 linux-image-4.4.0-157-powerpc-smp 4.4.0-157.185 linux-image-4.4.0-157-powerpc64-emb 4.4.0-157.185 linux-image-4.4.0-157-powerpc64-smp 4.4.0-157.185 linux-image-aws 4.4.0.1088.91 linux-image-generic 4.4.0.157.165 linux-image-generic-lpae 4.4.0.157.165 linux-image-kvm 4.4.0.1052.52 linux-image-lowlatency 4.4.0.157.165 linux-image-powerpc-e500mc 4.4.0.157.165 linux-image-powerpc-smp 4.4.0.157.165 linux-image-powerpc64-emb 4.4.0.157.165 linux-image-powerpc64-smp 4.4.0.157.165 linux-image-raspi2 4.4.0.1117.117 linux-image-virtual 4.4.0.157.165 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.
