TITLE

Linux Kernel Vulnerable to resource exhaustion

DESCRIPTION

Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-d10dcb615c8e. Linux Kernel Contains a resource exhaustion vulnerability. Vendors have confirmed this vulnerability CID-d10dcb615c8e It is released as.Service operation interruption (DoS) There is a possibility of being put into a state. Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/linux-4.4.208/*: Upgraded. IPV6_MULTIPLE_TABLES n -> y +IPV6_SUBTREES y These updates fix various bugs and security issues. Be sure to upgrade your initrd after upgrading the kernel packages. If you use lilo to boot your machine, be sure lilo.conf points to the correct kernel and initrd and run lilo as root to update the bootloader. If you use elilo to boot your machine, you should run eliloconfig to copy the kernel and initrd to the EFI System Partition.

For a 32-bit SMP machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.208-smp | bash For a 64-bit machine, or a 32-bit uniprocessor machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2): # /usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.208 | bash Please note that "uniprocessor" has to do with the kernel you are running, not with the CPU. Most systems should run the SMP kernel (if they can) regardless of the number of cores the CPU has. If you aren't sure which kernel you are running, run "uname -a". If you see SMP there, you are running the SMP kernel and should use the 4.4.208-smp version when running mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit systems should always use 4.4.208 as the version. If you are using lilo or elilo to boot the machine, you'll need to ensure that the machine is properly prepared before rebooting. If using LILO: By default, lilo.conf contains an image= line that references a symlink that always points to the correct kernel. No editing should be required unless your machine uses a custom lilo.conf. If that is the case, be sure that the image= line references the correct kernel file. Either way, you'll need to run "lilo" as root to reinstall the boot loader. If using elilo: Ensure that the /boot/vmlinuz symlink is pointing to the kernel you wish to use, and then run eliloconfig to update the EFI System Partition. +-----+ Slackware Linux Security Team http://slackware.com/gpg-key security@slackware.com +------------------------------------------------------------------------+ | To leave the slackware-security mailing list: | +------------------------------------------------------------------------+ | Send an email to majordomo@slackware.com with this text in the body of | | the email message: | | | | unsubscribe slackware-security | | | | You will get a confirmation message back containing instructions to | | complete the process.

Software Description: - linux-azure: Linux kernel for Microsoft Azure Cloud systems Details: USN-4287-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. 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 Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. (CVE-2019-14615) It was discovered that the Atheros 802.11ac wireless USB device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15099) It was discovered that the HSA Linux kernel driver for AMD GPU devices did not properly check for errors in certain situations, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service. (CVE-2019-16229) It was discovered that the Marvell 8xxx Libertas WLAN device driver in the Linux kernel did not properly check for errors in certain situations, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service. (CVE-2019-16232) It was discovered that a race condition existed in the Virtual Video Test Driver in the Linux kernel. An attacker with write access to /dev/video0 on a system with the vivid module loaded could possibly use this to gain administrative privileges. (CVE-2019-18683) It was discovered that the Renesas Digital Radio Interface (DRIF) driver in the Linux kernel did not properly initialize data. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2019-18786) It was discovered that the Afatech AF9005 DVB-T USB device driver in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-18809) It was discovered that the btrfs file system in the Linux kernel did not properly validate metadata, leading to a NULL pointer dereference. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). (CVE-2019-19057) It was discovered that the crypto subsystem in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19062) It was discovered that the Realtek rtlwifi USB device driver in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19063) It was discovered that the RSI 91x WLAN device driver in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19071) It was discovered that the Atheros 802.11ac wireless USB device driver in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19078) It was discovered that the AMD GPU device drivers in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-19082) Dan Carpenter discovered that the AppleTalk networking subsystem of the Linux kernel did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-19227) It was discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle ioctl requests to get emulated CPUID features. An attacker with access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-19332) It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle certain conditions. An attacker could use this to specially craft an ext4 file system that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-19767) Gao Chuan discovered that the SAS Class driver in the Linux kernel contained a race condition that could lead to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-19965) It was discovered that the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel did not properly deallocate memory in certain error conditions. (CVE-2019-20096) Mitchell Frank discovered that the Wi-Fi implementation in the Linux kernel when used as an access point would send IAPP location updates for stations before client authentication had completed. A physically proximate attacker could use this to cause a denial of service. (CVE-2019-5108) It was discovered that a race condition can lead to a use-after-free while destroying GEM contexts in the i915 driver for the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-7053) It was discovered that the B2C2 FlexCop USB device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15291) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: linux-image-4.15.0-1069-azure 4.15.0-1069.74~14.04.1 linux-image-azure 4.15.0.1069.55 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.
