Vulnerability from variot

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. Linux Kernel Contains a classic buffer overflow vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. ========================================================================= Ubuntu Security Notice USN-4162-2 October 23, 2019

linux-azure vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in the Linux kernel. This update provides the corresponding updates for the Linux kernel for Microsoft Azure Cloud systems for Ubuntu 14.04 ESM.

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-2019-14814, CVE-2019-14815, 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)

Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel did not properly validate device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15117)

Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel improperly performed recursion while handling device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15118)

It was discovered that the Technisat DVB-S/S2 USB device driver in the Linux kernel contained a buffer overread. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-15505)

Brad Spengler discovered that a Spectre mitigation was improperly implemented in the ptrace susbsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information. (CVE-2019-15902)

It was discovered that the SMB networking file system implementation in the Linux kernel contained a buffer overread. An attacker could use this to expose sensitive information (kernel memory). (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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

Linux Kernel Contains a classic buffer overflow vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. =========================================================================\nUbuntu Security Notice USN-4162-2\nOctober 23, 2019\n\nlinux-azure vulnerabilities\n=========================================================================\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 14.04 ESM\n\nSummary:\n\nSeveral security issues were fixed in the Linux kernel. This update provides the corresponding updates for the Linux\nkernel for Microsoft Azure Cloud systems for Ubuntu 14.04 ESM. \n\nIt was discovered that the RSI 91x Wi-Fi driver in the Linux kernel did not\ndid not handle detach operations correctly, leading to a use-after-free\nvulnerability. (CVE-2019-14814,\nCVE-2019-14815, CVE-2019-14816)\n\nMatt Delco discovered that the KVM hypervisor implementation in the Linux\nkernel did not properly perform bounds checking when handling coalesced\nMMIO write operations. A local attacker with write access to /dev/kvm could\nuse this to cause a denial of service (system crash). (CVE-2019-14821)\n\nHui Peng and Mathias Payer discovered that the USB audio driver for the\nLinux kernel did not properly validate device meta data. A physically\nproximate attacker could use this to cause a denial of service (system\ncrash). (CVE-2019-15117)\n\nHui Peng and Mathias Payer discovered that the USB audio driver for the\nLinux kernel improperly performed recursion while handling device meta\ndata. A physically proximate attacker could use this to cause a denial of\nservice (system crash). (CVE-2019-15118)\n\nIt was discovered that the Technisat DVB-S/S2 USB device driver in the\nLinux kernel contained a buffer overread. A physically proximate attacker\ncould use this to cause a denial of service (system crash) or possibly\nexpose sensitive information. (CVE-2019-15505)\n\nBrad Spengler discovered that a Spectre mitigation was improperly\nimplemented in the ptrace susbsystem of the Linux kernel. A local attacker\ncould possibly use this to expose sensitive information. (CVE-2019-15902)\n\nIt was discovered that the SMB networking file system implementation in the\nLinux kernel contained a buffer overread. An attacker could use this to\nexpose sensitive information (kernel memory). (CVE-2019-15918)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 14.04 ESM:\n  linux-image-4.15.0-1061-azure   4.15.0-1061.66~14.04.1\n  linux-image-azure               4.15.0.1061.47\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA256\n\n=====================================================================\n                   Red Hat Security Advisory\n\nSynopsis:          Important: kernel security and bug fix update\nAdvisory ID:       RHSA-2020:0374-01\nProduct:           Red Hat Enterprise Linux\nAdvisory URL:      https://access.redhat.com/errata/RHSA-2020:0374\nIssue date:        2020-02-04\nCVE Names:         CVE-2019-14816 CVE-2019-14895 CVE-2019-14898 \n                   CVE-2019-14901 CVE-2019-17133 \n=====================================================================\n\n1.
