Vulnerability from variot

Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. An input validation error vulnerability exists in the Linux kernel version 4.9+. Description:

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. (BZ#1594915)

  1. As a consequence, the virtualized guests sometimes mishandled the request to perform the microcode update and became unresponsive in the early boot stage. (BZ#1618386)

  2. ========================================================================== Ubuntu Security Notice USN-3742-3 August 21, 2018

linux-lts-trusty regressions

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

  • Ubuntu 12.04 ESM

Summary:

USN-3742-2 introduced regressions in the Linux Hardware Enablement (HWE) kernel for Ubuntu 12.04 ESM.

Software Description: - linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise ESM

Details:

USN-3742-2 introduced mitigations in the Linux Hardware Enablement (HWE) kernel for Ubuntu 12.04 ESM to address L1 Terminal Fault (L1TF) vulnerabilities (CVE-2018-3620, CVE-2018-3646). Unfortunately, the update introduced regressions that caused kernel panics when booting in some environments as well as preventing Java applications from starting.

We apologize for the inconvenience.

Original advisory details:

It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local attacker in a guest virtual machine could use this to expose sensitive information (memory from other guests or the host OS). (CVE-2018-3646)

It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). (CVE-2018-3620)

Andrey Konovalov discovered an out-of-bounds read in the POSIX timers subsystem in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. A remote attacker could use this to cause a denial of service. A remote attacker could use this to cause a denial of service. (CVE-2018-5391)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.04 ESM: linux-image-3.13.0-156-generic 3.13.0-156.206~precise1 linux-image-3.13.0-156-generic-lpae 3.13.0-156.206~precise1 linux-image-generic-lpae-lts-trusty 3.13.0.156.146 linux-image-generic-lts-trusty 3.13.0.156.146

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. 6.6) - noarch, x86_64

Bug Fix(es):

  • After updating the system to prevent the L1 Terminal Fault (L1TF) vulnerability, only one thread was detected on systems that offer processing of two threads on a single processor core. With this update, the "__max_smt_threads()" function has been fixed. (BZ#1625334)

  • Previously, a kernel panic occurred when the kernel tried to make an out of bound access to the array that describes the L1 Terminal Fault (L1TF) mitigation state on systems without Extended Page Tables (EPT) support. This update extends the array of mitigation states to cover all the states, which effectively prevents out of bound array access. Also, this update enables rejecting invalid, irrelevant values, that might be erroneously provided by the userspace. (BZ#1629633)

  1. Description:

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646)

  • An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to influence speculative execution and/or read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3693)

  • A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. (CVE-2018-5390)

  • kernel: crypto: privilege escalation in skcipher_recvmsg function (CVE-2017-13215)

  • kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact (CVE-2018-10675)

  • kernel: race condition in snd_seq_write() may lead to UAF or OOB access (CVE-2018-7566)

  1. Consequently, the node was not available. This update fixes an irq latency source in memory compaction. As a result, nodes no longer get into "NodeNotReady" state under the described circumstances. (BZ#1596281)

  2. Previously, the kernel source code was missing support to report the Speculative Store Bypass Disable (SSBD) vulnerability status on IBM Power Systems and the little-endian variants of IBM Power Systems. As a consequence, the /sys/devices/system/cpu/vulnerabilities/spec_store_bypass file incorrectly reported "Not affected" on both CPU architectures. This fix updates the kernel source code to properly report the SSBD status either as "Vulnerable" or "Mitigation: Kernel entry/exit barrier (TYPE)" where TYPE is one of "eieio", "hwsync", "fallback", or "unknown". As a consequence, the VMs sometimes became unresponsive when booting. This update applies an upstream patch to avoid early microcode update when running under a hypervisor. As a result, kernel hangs no longer occur in the described scenario. (BZ#1618388)

Description:\n\nThe kernel-rt packages provide the Real Time Linux Kernel, which enables\nfine-tuning for systems with extremely high determinism requirements. \n(BZ#1594915)\n\n4. As a consequence, the\nvirtualized guests sometimes mishandled the request to perform the\nmicrocode update and became unresponsive in the early boot stage.

Unfortunately, the\nupdate introduced regressions that caused kernel panics when booting\nin some environments as well as preventing Java applications from\nstarting. \n\nWe apologize for the inconvenience. \n\nOriginal advisory details:\n\n It was discovered that memory present in the L1 data cache of an Intel CPU\n core may be exposed to a malicious process that is executing on the CPU\n core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local\n attacker in a guest virtual machine could use this to expose sensitive\n information (memory from other guests or the host OS). (CVE-2018-3646)\n\n It was discovered that memory present in the L1 data cache of an Intel CPU\n core may be exposed to a malicious process that is executing on the CPU\n core. This vulnerability is also known as L1 Terminal Fault (L1TF). (CVE-2018-3620)\n\n Andrey Konovalov discovered an out-of-bounds read in the POSIX\n timers subsystem in the Linux kernel. A local attacker could use\n this to cause a denial of service (system crash) or expose sensitive\n information. A remote attacker could use this to cause a\n denial of service. A remote attacker could use this to\n cause a denial of service. (CVE-2018-5391)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 12.04 ESM:\n  linux-image-3.13.0-156-generic  3.13.0-156.206~precise1\n  linux-image-3.13.0-156-generic-lpae  3.13.0-156.206~precise1\n  linux-image-generic-lpae-lts-trusty  3.13.0.156.146\n  linux-image-generic-lts-trusty  3.13.0.156.146\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. 6.6) - noarch, x86_64\n\n3. \n\nBug Fix(es):\n\n* After updating the system to prevent the L1 Terminal Fault (L1TF)\nvulnerability, only one thread was detected on systems that offer\nprocessing of two threads on a single processor core. With this update, the\n\"__max_smt_threads()\" function has been fixed. (BZ#1625334)\n\n* Previously, a kernel panic occurred when the kernel tried to make an out\nof bound access to the array that describes the L1 Terminal Fault (L1TF)\nmitigation state on systems without Extended Page Tables (EPT) support. \nThis update extends the array of mitigation states to cover all the states,\nwhich effectively prevents out of bound array access. Also, this update\nenables rejecting invalid, irrelevant values, that might be erroneously\nprovided by the userspace.

Description:\n\nThe kernel packages contain the Linux kernel, the core of any Linux\noperating system. \n\nSecurity Fix(es):\n\n* Modern operating systems implement virtualization of physical memory to\nefficiently use available system resources and provide inter-domain\nprotection through access control and isolation. The L1TF issue was found\nin the way the x86 microprocessor designs have implemented speculative\nexecution of instructions (a commonly used performance optimisation) in\ncombination with handling of page-faults caused by terminated virtual to\nphysical address resolving process. As a result, an unprivileged attacker\ncould use this flaw to read privileged memory of the kernel or other\nprocesses and/or cross guest/host boundaries to read host memory by\nconducting targeted cache side-channel attacks. (CVE-2018-3620,\nCVE-2018-3646)\n\n* An industry-wide issue was found in the way many modern microprocessor\ndesigns have implemented speculative execution of instructions past bounds\ncheck. The flaw relies on the presence of a precisely-defined instruction\nsequence in the privileged code and the fact that memory writes occur to an\naddress which depends on the untrusted value. Such writes cause an update\ninto the microprocessor\u0027s data cache even for speculatively executed\ninstructions that never actually commit (retire). As a result, an\nunprivileged attacker could use this flaw to influence speculative\nexecution and/or read privileged memory by conducting targeted cache\nside-channel attacks. (CVE-2018-3693)\n\n* A flaw named SegmentSmack was found in the way the Linux kernel handled\nspecially crafted TCP packets. A remote attacker could use this flaw to\ntrigger time and calculation expensive calls to tcp_collapse_ofo_queue()\nand tcp_prune_ofo_queue() functions by sending specially modified packets\nwithin ongoing TCP sessions which could lead to a CPU saturation and hence\na denial of service on the system. Maintaining the denial of service\ncondition requires continuous two-way TCP sessions to a reachable open\nport, thus the attacks cannot be performed using spoofed IP addresses. \n(CVE-2018-5390)\n\n* kernel: crypto: privilege escalation in skcipher_recvmsg function\n(CVE-2017-13215)\n\n* kernel: mm: use-after-free in do_get_mempolicy function allows local DoS\nor other unspecified impact (CVE-2018-10675)\n\n* kernel: race condition in snd_seq_write() may lead to UAF or OOB access\n(CVE-2018-7566)\n\nFor more details about the security issue(s), including the impact, a CVSS\nscore, and other related information, refer to the CVE page(s) listed in\nthe References section. \n\nRed Hat would like to thank Intel OSSIRT (Intel.com) for reporting\nCVE-2018-3620 and CVE-2018-3646; Vladimir Kiriansky (MIT) and Carl\nWaldspurger (Carl Waldspurger Consulting) for reporting CVE-2018-3693; and\nJuha-Matti Tilli (Aalto University, Department of Communications and\nNetworking and Nokia Bell Labs) for reporting CVE-2018-5390. \n\nBug Fix(es):\n\nThese updated kernel packages include also numerous bug fixes.

Consequently, the node was not available. This\nupdate fixes an irq latency source in memory compaction. As a result, nodes\nno longer get into \"NodeNotReady\" state under the described circumstances. \n(BZ#1596281)\n\n* Previously, the kernel source code was missing support to report the\nSpeculative Store Bypass Disable (SSBD) vulnerability status on IBM Power\nSystems and the little-endian variants of IBM Power Systems. As a\nconsequence, the /sys/devices/system/cpu/vulnerabilities/spec_store_bypass\nfile incorrectly reported \"Not affected\" on both CPU architectures. This\nfix updates the kernel source code to properly report the SSBD status\neither as \"Vulnerable\" or \"Mitigation: Kernel entry/exit barrier (TYPE)\"\nwhere TYPE is one of \"eieio\", \"hwsync\", \"fallback\", or \"unknown\". As a\nconsequence, the VMs sometimes became unresponsive when booting. This\nupdate applies an upstream patch to avoid early microcode update when\nrunning under a hypervisor. As a result, kernel hangs no longer occur in\nthe described scenario. (BZ#1618388)\n\n4",
