TITLE

Linux kernel Buffer error vulnerability

DESCRIPTION

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. This update provides the corresponding updates for the Linux kernel for Microsoft Azure Cloud systems for Ubuntu 14.04 ESM. (CVE-2019-15918) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: linux-image-4.15.0-1061-azure 4.15.0-1061.66~14.04.1 linux-image-azure 4.15.0.1061.47 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. ========================================================================== Kernel Live Patch Security Notice 0058-1 October 22, 2019 linux vulnerability ========================================================================== A security issue affects these releases of Ubuntu: | Series | Base kernel | Arch | flavors | |------------------+--------------+----------+------------------| | Ubuntu 18.04 LTS | 4.15.0 | amd64 | aws | | Ubuntu 18.04 LTS | 4.15.0 | amd64 | generic | | Ubuntu 18.04 LTS | 4.15.0 | amd64 | lowlatency | | Ubuntu 18.04 LTS | 4.15.0 | amd64 | oem | | Ubuntu 18.04 LTS | 5.0.0 | amd64 | azure | | Ubuntu 14.04 LTS | 4.4.0 | amd64 | generic | | Ubuntu 14.04 LTS | 4.4.0 | amd64 | lowlatency | | Ubuntu 16.04 LTS | 4.4.0 | amd64 | aws | | Ubuntu 16.04 LTS | 4.4.0 | amd64 | generic | | Ubuntu 16.04 LTS | 4.4.0 | amd64 | lowlatency | | Ubuntu 16.04 LTS | 4.15.0 | amd64 | azure | | Ubuntu 16.04 LTS | 4.15.0 | amd64 | generic | | Ubuntu 16.04 LTS | 4.15.0 | amd64 | lowlatency | Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: It was discovered that a race condition existed in the GFS2 file system in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2016-10905) It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. (CVE-2018-20856) It was discovered that the USB gadget Midi driver in the Linux kernel contained a double-free vulnerability when handling certain error conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-20961) It was discovered that the XFS file system in the Linux kernel did not properly handle mount failures in some situations. (CVE-2018-20976) It was discovered that the RSI 91x Wi-Fi driver in the Linux kernel did not did not handle detach operations correctly, leading to a use-after-free vulnerability. (CVE-2018-21008) It was discovered that the Intel Wi-Fi device driver in the Linux kernel did not properly validate certain Tunneled Direct Link Setup (TDLS). A physically proximate attacker could use this to cause a denial of service (Wi-Fi disconnect). (CVE-2019-0136) 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) It was discovered that an integer overflow existed in the Binder implementation of the Linux kernel, leading to a buffer overflow. A local attacker could use this to escalate privileges. (CVE-2019-2181) It was discovered that the Marvell Wireless LAN device driver in the Linux kernel did not properly validate the BSS descriptor. (CVE-2019-3846) It was discovered that a heap buffer overflow existed in the Marvell Wireless LAN device driver for the Linux kernel. (CVE-2019-10126) It was discovered that the Bluetooth UART implementation in the Linux kernel did not properly check for missing tty operations. A local attacker could use this to cause a denial of service. (CVE-2019-10207) Jonathan Looney discovered that an integer overflow existed in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service (system crash). (CVE-2019-11477) Jonathan Looney discovered that the TCP retransmission queue implementation in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could use this to cause a denial of service. (CVE-2019-11478) 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 PowerPC dlpar implementation in the Linux kernel did not properly check for allocation errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-12614) 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) Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. (CVE-2019-14814) Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. (CVE-2019-14815) Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. (CVE-2019-14816) Matt Delco discovered that the KVM hypervisor implementation in the Linux kernel did not properly perform bounds checking when handling coalesced MMIO write operations. A local attacker with write access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-14821) Peter Pi discovered a buffer overflow in the virtio network backend (vhost_net) implementation in the Linux kernel.
