CVE-2019-11085

TITLE

Intel Multiple vulnerabilities in the product

DESCRIPTION

Insufficient input validation in Kernel Mode Driver in Intel(R) i915 Graphics for Linux before version 5.0 may allow an authenticated user to potentially enable escalation of privilege via local access. Linux for Intel(R) i915 Graphics Contains an input validation vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Linux Kernel is prone to a local privilege-escalation vulnerability. An attacker can exploit this issue to to gain elevated privileges. Linux versions prior to 5.0 are vulnerable. (CVE-2018-13053). 7.4) - noarch, x86_64 3. Bug Fix(es): * core: backports from upstream (BZ#1794372) Enhancement(s): * Selective backport: perf: Sync with upstream v4.16 (BZ#1782750) 4. 7.5) - ppc64, ppc64le, x86_64 3. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security, bug fix, and enhancement update Advisory ID: RHSA-2019:1873-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2019:1873 Issue date: 2019-07-29 CVE Names: CVE-2018-16871 CVE-2018-16884 CVE-2019-11085 CVE-2019-11811 ==================================================================== 1.

Software Description: - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-aws-hwe: Linux kernel for Amazon Web Services (AWS-HWE) systems Details: It was discovered that the alarmtimer implementation in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service. (CVE-2018-13053) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly track inode validations. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service (system crash). (CVE-2018-13093) Wen Xu discovered that the f2fs file system implementation in the Linux kernel did not properly validate metadata. An attacker could use this to construct a malicious f2fs image that, when mounted, could cause a denial of service (system crash). (CVE-2018-13096, CVE-2018-13097, CVE-2018-13098, CVE-2018-13099, CVE-2018-13100, CVE-2018-14614, CVE-2018-14615, CVE-2018-14616) Wen Xu and Po-Ning Tseng discovered that btrfs file system implementation in the Linux kernel did not properly validate metadata. An attacker could use this to construct a malicious btrfs image that, when mounted, could cause a denial of service (system crash). (CVE-2018-14609, CVE-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613) Wen Xu discovered that the HFS+ filesystem implementation in the Linux kernel did not properly handle malformed catalog data in some situations. An attacker could use this to construct a malicious HFS+ image that, when mounted, could cause a denial of service (system crash). (CVE-2018-14617) Vasily Averin and Pavel Tikhomirov discovered that the cleancache subsystem of the Linux kernel did not properly initialize new files in some situations. A local attacker could use this to expose sensitive information. (CVE-2018-16862) Hui Peng and Mathias Payer discovered that the Option USB High Speed driver in the Linux kernel did not properly validate metadata received from the device. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2018-19985) Hui Peng and Mathias Payer discovered that the USB subsystem in the Linux kernel did not properly handle size checks when handling an extra USB descriptor. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2018-20169) Zhipeng Xie discovered that an infinite loop could triggered in the CFS Linux kernel process scheduler. A local attacker could possibly use this to cause a denial of service. (CVE-2018-20784) It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code.

(CVE-2019-3819) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-1047-aws 4.15.0-1047.49 linux-image-aws 4.15.0.1047.46 Ubuntu 16.04 LTS: linux-image-4.15.0-1047-aws 4.15.0-1047.49~16.04.1 linux-image-aws-hwe 4.15.0.1047.47 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.
