HIGH Summary
In the Linux kernel before 4.9.3, fs/xfs/xfs_aops.c allows local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Leveraging Race Conditions This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
- Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

NASL family Huawei Local Security Checks NASL id EULEROS_SA-2019-1244.NASL description According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - A flaw was found In the Linux kernel, through version 4.19.6, where 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. An attacker could corrupt memory and possibly escalate privileges if the attacker is able to have physical access to the system.i1/4^CVE-2018-19824i1/4%0 - It was found that the Linux kernel can hit a BUG_ON() statement in the __xfs_get_blocks() in the fs/xfs/xfs_aops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUG_ON() instead of an I/O failure. This allows a local unprivileged attacker to cause a system crash and a denial of service.i1/4^CVE-2016-10741i1/4%0 - A division-by-zero in set_termios(), when debugging is enabled, was found in the Linux kernel. When the [io_ti] driver is loaded, a local unprivileged attacker can request incorrect high transfer speed in the change_port_settings() in the drivers/usb/serial/io_ti.c so that the divisor value becomes zero and causes a system crash resulting in a denial of service.i1/4^CVE-2017-18360i1/4%0 - Since Linux kernel version 3.2, 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.i1/4^CVE-2018-18281i1/4%0 - A use-after-free flaw can occur in the Linux kernel due to a race condition between packet_do_bind() and packet_notifier() functions called for an AF_PACKET socket. An unprivileged, local user could use this flaw to induce kernel memory corruption on the system, leading to an unresponsive system or to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.i1/4^CVE-2018-18559i1/4%0 Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-03-19 modified 2019-04-04 plugin id 123712 published 2019-04-04 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/123712 title EulerOS Virtualization 2.5.3 : kernel (EulerOS-SA-2019-1244) code # # (C) Tenable Network Security, Inc. # include("compat.inc"); if (description) { script_id(123712); script_version("1.5"); script_set_attribute(attribute:"plugin_modification_date", value:"2020/03/19"); script_cve_id( "CVE-2016-10741", "CVE-2017-18360", "CVE-2018-18281", "CVE-2018-18559", "CVE-2018-19824" ); script_name(english:"EulerOS Virtualization 2.5.3 : kernel (EulerOS-SA-2019-1244)"); script_summary(english:"Checks the rpm output for the updated packages."); script_set_attribute(attribute:"synopsis", value: "The remote EulerOS Virtualization host is missing multiple security updates."); script_set_attribute(attribute:"description", value: "According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - A flaw was found In the Linux kernel, through version 4.19.6, where 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.

The following security bugs were fixed : CVE-2016-10741: fs/xfs/xfs_aops.c allowed local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure (bnc#1114920 bnc#1124010). CVE-2017-18360: In change_port_settings in drivers/usb/serial/io_ti.c local users could cause a denial of service by division-by-zero in the serial device layer by trying to set very high baud rates (bnc#1123706). 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-2018-19407: 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-2018-19824: 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-2018-19985: 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-2018-20169: 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-2019-7222: A information leak in exception handling in KVM could be used to expose host memory to guests. (bnc#1124735). The update package also includes non-security fixes.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * An use-after-free flaw was found in the Linux kernel which enables a race condition in the L2TPv3 IP Encapsulation feature. A local user could use this flaw to escalate their privileges or crash the system. (CVE-2016-10200, Important) * A flaw was found that can be triggered in keyring_search_iterator in keyring.c if type->match is NULL. A local user could use this flaw to crash the system or, potentially, escalate their privileges. (CVE-2017-2647, Important) * It was found that the NFSv4 server in the Linux kernel did not properly validate layout type when processing NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A remote attacker could use this flaw to soft-lockup the system and thus cause denial of service. (CVE-2017-8797, Important) This update also fixes multiple Moderate and Low impact security issues : * CVE-2015-8839, CVE-2015-8970, CVE-2016-9576, CVE-2016-7042, CVE-2016-7097, CVE-2016-8645, CVE-2016-9576, CVE-2016-9588, CVE-2016-9806, CVE-2016-10088, CVE-2016-10147, CVE-2017-2596, CVE-2017-2671, CVE-2017-5970, CVE-2017-6001, CVE-2017-6951, CVE-2017-7187, CVE-2017-7616, CVE-2017-7889, CVE-2017-8890, CVE-2017-9074, CVE-2017-8890, CVE-2017-9075, CVE-2017-8890, CVE-2017-9076, CVE-2017-8890, CVE-2017-9077, CVE-2017-9242, CVE-2014-7970, CVE-2014-7975, CVE-2016-6213, CVE-2016-9604, CVE-2016-9685 Documentation for these issues is available from the Release Notes document linked from the References section.

A malicious user/process could use 'in memory' page-cache knowledge to infer access timings to shared memory and gain knowledge which can be used to reduce effectiveness of cryptographic strength by monitoring algorithmic behavior, infer access patterns of memory to determine code paths taken, and exfiltrate data to a blinded attacker through page-granularity access times as a side-channel.(CVE-2019-5489) - It was found that the Linux kernel can hit a BUG_ON() statement in the __xfs_get_blocks() in the fs/xfs/xfs_aops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUG_ON() instead of an I/O failure. This allows a local unprivileged attacker to cause a system crash and a denial of service.(CVE-2016-10741) - An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel. An attacker with a local account can trick the stack unwinder code to leak stack contents to userspace. The fix allows only root to inspect the kernel stack of an arbitrary task.(CVE-2018-17972) - A security flaw was found in the Linux kernel 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.(CVE-2018-16862) - A use-after-free flaw can occur in the Linux kernel due to a race condition between packet_do_bind() and packet_notifier() functions called for an AF_PACKET socket. An unprivileged, local user could use this flaw to induce kernel memory corruption on the system, leading to an unresponsive system or to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.(CVE-2018-18559) - A flaw was found In the Linux kernel, through version 4.19.6, where 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. An attacker could corrupt memory and possibly escalate privileges if the attacker is able to have physical access to the system.(CVE-2018-19824) - A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact may occur by renaming a file in a crafted ext4 filesystem image.(CVE-2018-10879) - A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.(CVE-2018-10883) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

For more information on this set of information leaks, check out https://www.suse.com/support/kb/doc/?id=7023736 The following security bugs were fixed: CVE-2016-10741: fs/xfs/xfs_aops.c allowed local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure (bnc#1114920 bnc#1124010). CVE-2017-1000407: By flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (bnc#1071021). CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066674). CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240). CVE-2017-7472: The KEYS subsystem allowed local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls (bnc#1034862). CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host.

An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system.(CVE-2014-3185i1/4%0 - Use-after-free vulnerability in the msm_set_crop function in drivers/media/video/msm/msm_camera.c in the MSM-Camera driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to gain privileges or cause a denial of service (memory corruption) via an application that makes a crafted ioctl call.(CVE-2015-0568i1/4%0 - The vivid_fb_ioctl function in drivers/media/platform/vivid/vivid-osd.c in the Linux kernel through 4.3.3 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory via a crafted application.(CVE-2015-7884i1/4%0 - The usb_get_bos_descriptor function in drivers/usb/core/config.c in the Linux kernel can allow a local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device.(CVE-2017-16535i1/4%0 - The ACPI parsing functionality in the Linux kernel does not flush the node and node_ext caches which causes a kernel stack dump. This allows local users to obtain sensitive information from kernel memory and use this information to bypass the KASLR protection mechanism by creating and applying crafted ACPI table.(CVE-2017-13694i1/4%0 - The is_ashmem_file function in drivers/staging/android/ashmem.c in a certain Qualcomm Innovation Center (QuIC) Android patch for the Linux kernel 3.x mishandles pointer validation within the KGSL Linux Graphics Module, which allows attackers to bypass intended access restrictions by using the /ashmem string as the dentry name.(CVE-2016-5340i1/4%0 - It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system.(CVE-2013-4312i1/4%0 - Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is unlikely.(CVE-2017-7541i1/4%0 - A flaw in the netback module allowed frontends to control mapping of requests to request queues. An attacker can change this mapping by requesting invalid mapping requests allowing the (usually privileged) backend to access out-of-bounds memory access for reading and writing.(CVE-2018-15471i1/4%0 - A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver firewire-net in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution.The flaw requires firewire-net module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network.(CVE-2016-8633i1/4%0 - It was found that the Linux kernel can hit a BUG_ON() statement in the __xfs_get_blocks() in the fs/xfs/xfs_aops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUG_ON() instead of an I/O failure. This allows a local unprivileged attacker to cause a system crash and a denial of service.(CVE-2016-10741i1/4%0 - A vulnerability was found in the Linux kernel. The pointer to the netlink socket attribute is not checked, which could cause a null pointer dereference when parsing the nested attributes in function tipc_nl_publ_dump(). This allows local users to cause a DoS.(CVE-2016-4951i1/4%0 - It was reported that with Linux kernel, earlier than version v4.10-rc8, an application may trigger a BUG_ON in sctp_wait_for_sndbuf if the socket tx buffer is full, a thread is waiting on it to queue more data, and meanwhile another thread peels off the association being used by the first thread.(CVE-2017-5986i1/4%0 - The kvm_vm_ioctl_check_extension function in arch/powerpc/kvm/powerpc.c in the Linux kernel before 4.13.11 allows local users to cause a denial of service (NULL pointer dereference and system crash) via a KVM_CHECK_EXTENSION KVM_CAP_PPC_HTM ioctl call to /dev/kvm.(CVE-2017-15306i1/4%0 - A flaw was found in the way the Linux kernel last seen 2020-03-19 modified 2019-05-14 plugin id 124970 published 2019-05-14 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/124970 title EulerOS Virtualization for ARM 64 3.0.1.0 : kernel (EulerOS-SA-2019-1517) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2017-2077.NASL description An update for kernel-rt is now available for Red Hat Enterprise Linux 7.
