HIGH Summary
A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.

NASL family SuSE Local Security Checks NASL id OPENSUSE-2019-65.NASL description The openSUSE Leap 15.0 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841). - CVE-2018-14625: An attacker might have bene able to have an uncontrolled read to kernel-memory from within a vm guest. A race condition between connect() and close() function may allow an attacker using the AF_VSOCK protocol to gather a 4 byte information leak or possibly intercept or corrupt AF_VSOCK messages destined to other clients (bnc#1106615). - CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bsc#1120743). - CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946). - CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714). - CVE-2018-18397: The userfaultfd implementation mishandled access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c (bnc#1117656). - CVE-2018-12232: In net/socket.c there was a race condition between fchownat and close in cases where they target the same socket file descriptor, related to the sock_close and sockfs_setattr functions. fchownat did not increment the file descriptor reference count, which allowed close to set the socket to NULL during fchownat last seen 2020-03-18 modified 2019-01-22 plugin id 121289 published 2019-01-22 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/121289 title openSUSE Security Update : the Linux Kernel (openSUSE-2019-65) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from openSUSE Security Update openSUSE-2019-65. # # The text description of this plugin is (C) SUSE LLC. # include("compat.inc"); if (description) { script_id(121289); script_version("1.5"); script_set_attribute(attribute:"plugin_modification_date", value:"2020/02/24"); script_cve_id("CVE-2013-2547", "CVE-2018-12232", "CVE-2018-14625", "CVE-2018-16862", "CVE-2018-16884", "CVE-2018-18397", "CVE-2018-19407", "CVE-2018-19824", "CVE-2018-19854", "CVE-2018-19985", "CVE-2018-20169", "CVE-2018-9568"); script_name(english:"openSUSE Security Update : the Linux Kernel (openSUSE-2019-65)"); script_summary(english:"Check for the openSUSE-2019-65 patch"); script_set_attribute( attribute:"synopsis", value:"The remote openSUSE host is missing a security update." ); script_set_attribute( attribute:"description", value: "The openSUSE Leap 15.0 kernel was updated to receive various security and bugfixes.

This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (bnc#1118319). - CVE-2018-16862: A security flaw was found in the way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one (bnc#1117186). - CVE-2018-19854: An issue was discovered in the crypto_report_one() and related functions in crypto/crypto_user.c (the crypto user configuration API) do not fully initialize structures that are copied to userspace, potentially leaking sensitive memory to user programs. NOTE: this is a CVE-2013-2547 regression but with easier exploitability because the attacker did not need a capability (however, the system must have the CONFIG_CRYPTO_USER kconfig option) (bnc#1118428). - CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).

SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-19985: The function hso_probe read if_num from the USB device (as an u8) and used it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data that could be used by local attackers (bnc#1120743). CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946). CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714). CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (bnc#1118319). CVE-2018-16862: A security flaw was found in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one (bnc#1117186). CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152). CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769). CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751). CVE-2018-18690: A local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandled ATTR_REPLACE operations with conversion of an attr from short to long form (bnc#1105025). CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825). CVE-2018-9516: In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. (bnc#1108498). CVE-2019-3459, CVE-2019-3460: The Blutooth stack suffered from two remote information leak vulnerabilities in the code that handles incoming L2cap configuration packets (bsc#1120758). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 122343 published 2019-02-20 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/122343 title SUSE SLES12 Security Update : kernel (SUSE-SU-2019:0439-1) NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-3981-1.NASL description Ke Sun, Henrique Kawakami, Kekai Hu, Rodrigo Branco, Giorgi Maisuradze, Dan Horea Lutas, Andrei Lutas, Volodymyr Pikhur, Stephan van Schaik, Alyssa Milburn, Sebastian Osterlund, Pietro Frigo, Kaveh Razavi, Herbert Bos, Cristiano Giuffrida, Moritz Lipp, Michael Schwarz, and Daniel Gruss discovered that memory previously stored in microarchitectural fill buffers of an Intel CPU core may be exposed to a malicious process that is executing on the same CPU core.

A local attacker could use this to expose sensitive information. (CVE-2018-12126) Vasily Averin and Evgenii Shatokhin discovered that a use-after-free vulnerability existed in the NFS41+ subsystem when multiple network namespaces are in use. A local attacker in a container could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

A local attacker could use this to expose sensitive information. (CVE-2019-11091) Matteo Croce, Natale Vinto, and Andrea Spagnolo discovered that the cgroups subsystem of the Linux kernel did not properly account for SCTP socket buffers. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-3874) Alex Williamson discovered that the vfio subsystem of the Linux kernel did not properly limit DMA mappings. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-3882) Hugues Anguelkov discovered that the Broadcom Wifi driver in the Linux kernel contained a heap buffer overflow. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-9500) Hugues Anguelkov discovered that the Broadcom Wifi driver in the Linux kernel did not properly prevent remote firmware events from being processed for USB Wifi devices. A physically proximate attacker could use this to send firmware events to the device. (CVE-2019-9503).

CVE-2018-14625 A use-after-free bug was found in the vhost driver for the Virtual Socket protocol. If this driver is used to communicate with a malicious virtual machine guest, the guest could read sensitive information from the host kernel. CVE-2018-16884 A flaw was found in the NFS 4.1 client implementation. Mounting NFS shares in multiple network namespaces at the same time could lead to a user-after-free. Local users might be able to use this for denial of service (memory corruption or crash) or possibly for privilege escalation. This can be mitigated by disabling unprivileged users from creating user namespaces, which is the default in Debian. CVE-2018-19824 Hui Peng and Mathias Payer discovered a use-after-free bug in the USB audio driver. A physically present attacker able to attach a specially designed USB device could use this for privilege escalation. CVE-2018-19985 Hui Peng and Mathias Payer discovered a missing bounds check in the hso USB serial driver. A physically present user able to attach a specially designed USB device could use this to read sensitive information from the kernel or to cause a denial of service (crash). CVE-2018-20169 Hui Peng and Mathias Payer discovered missing bounds checks in the USB core. A physically present attacker able to attach a specially designed USB device could use this to cause a denial of service (crash) or possibly for privilege escalation. CVE-2018-1000026 It was discovered that Linux could forward aggregated network packets with a segmentation size too large for the output device. In the specific case of Broadcom NetXtremeII 10Gb adapters, this would result in a denial of service (firmware crash). This update adds a mitigation to the bnx2x driver for this hardware. CVE-2019-3459, CVE-2019-3460 Shlomi Oberman, Yuli Shapiro and Karamba Security Ltd. research team discovered missing range checks in the Bluetooth L2CAP implementation. If Bluetooth is enabled, a nearby attacker could use these to read sensitive information from the kernel. CVE-2019-3701 Muyu Yu and Marcus Meissner reported that the CAN gateway implementation allowed the frame length to be modified, typically resulting in out-of-bounds memory-mapped I/O writes. On a system with CAN devices present, a local user with CAP_NET_ADMIN capability in the initial net namespace could use this to cause a crash (oops) or other hardware-dependent impact. CVE-2019-3819 A potential infinite loop was discovered in the HID debugfs interface exposed under /sys/kernel/debug/hid. A user with access to these files could use this for denial of service. This interface is only accessible to root by default, which fully mitigates the issue. CVE-2019-6974 Jann Horn reported a use-after-free bug in KVM. A local user with access to /dev/kvm could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2019-7221 Jim Mattson and Felix Wilhelm reported a user-after-free bug in KVM last seen 2020-06-01 modified 2020-06-02 plugin id 124595 published 2019-05-06 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/124595 title Debian DLA-1771-1 : linux-4.9 security update NASL family Virtuozzo Local Security Checks NASL id VIRTUOZZO_VZA-2018-089.NASL description According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerability : - A flaw was found in the implementation of NFS v4.1 in the Linux kernel. NFS v4.1 shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel ID and cause a use-after-free. A malicious user in a container can exploit this to cause a host kernel memory corruption and a system crash.
