ID CVE-2018-12232
Summary In net/socket.c in the Linux kernel through 4.17.1, there is 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 does not increment the file descriptor reference count, which allows close to set the socket to NULL during fchownat's execution, leading to a NULL pointer dereference and system crash.

  • 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 id SUSE_SU-2019-0224-1.NASL
    description The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes. This update brings following features : Support for Enhanced-IBRS on new Intel CPUs (fate#326564) The following security bugs were fixed: 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-2018-12232: In net/socket.c there is 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's execution, leading to a NULL pointer dereference and system crash (bnc#1097593). CVE-2018-14625: A flaw was found where an attacker may be 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-2018-16862: 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-2018-16884: 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-2018-18281: 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-2018-18397: 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-2018-18710: 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-2018-19407: 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-2018-19854: 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-2018-19985: 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). 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.

    title openSUSE Security Update : the Linux Kernel (openSUSE-2019-65)
  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2018-2948.NASL
    description An update for kernel-alt is now available for Red Hat Enterprise Linux 7. 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-alt packages provide the Linux kernel version 4.x. Security Fix(es) : * An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently 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 read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639, aarch64) * 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) * A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system. (CVE-2018-5391) Space precludes documenting all of the security fixes in this advisory. See the descriptions of the remaining security fixes in the related Knowledge Article : https://access.redhat.com/articles/3658021 For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting CVE-2018-3639; Juha-Matti Tilli (Aalto University - Department of Communications and Networking and Nokia Bell Labs) for reporting CVE-2018-5390 and CVE-2018-5391; Qualys Research Labs for reporting CVE-2018-1120; David Rientjes (Google) for reporting CVE-2018-1000200; and Wen Xu for reporting CVE-2018-1092, CVE-2018-1094, and CVE-2018-1095. The CVE-2018-14619 issue was discovered by Florian Weimer (Red Hat) and Ondrej Mosnacek (Red Hat). Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.6 Release Notes linked from the References section.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_SU-2019-0222-1.NASL
    description The SUSE Linux Enterprise 12 SP4 kernel for Azure 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 was uninitialized (bnc#1116841). 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 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-2018-14625: A flaw was found where an attacker may be 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 (bnc#1120743). CVE-2018-12232: In net/socket.c there is 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's execution, leading to a NULL pointer dereference and system crash (bnc#1097593). 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-2018-19854: 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). 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-2017-5753: Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis (bnc#1074578) 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.

    description It was discovered that, when attempting to handle an out-of-memory situation, a NULL pointer dereference could be triggered in the Linux kernel in some circumstances. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-1000200) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly validate meta-data information. An attacker could use this to construct a malicious xfs image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10323) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly validate xattr information. An attacker could use this to construct a malicious xfs image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10840) Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly keep meta-data information consistent in some situations. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10881) Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly handle corrupted meta data in some situations. An attacker could use this to specially craft an ext4 filesystem that caused a denial of service (system crash) when mounted. (CVE-2018-1093) Jann Horn discovered that the Linux kernel's implementation of random seed data reported that it was in a ready state before it had gathered sufficient entropy. An attacker could use this to expose sensitive information. (CVE-2018-1108) It was discovered that the procfs filesystem did not properly handle processes mapping some memory elements onto files. A local attacker could use this to block utilities that examine the procfs filesystem to report operating system state, such as ps(1). (CVE-2018-1120) Jann Horn discovered that the ext4 filesystem implementation in the Linux kernel did not properly keep xattr information consistent in some situations. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-11412) Piotr Gabriel Kosinski and Daniel Shapira discovered a stack-based buffer overflow in the CDROM driver implementation of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-11506) Shankara Pailoor discovered that a race condition existed in the socket handling code in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-12232) Shankara Pailoor discovered that the JFS filesystem implementation in the Linux kernel contained a buffer overflow when handling extended attributes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-12233) Felix Wilhelm discovered that the KVM implementation in the Linux kernel did not properly perform permission checks in some situations when nested virtualization is used. An attacker in a guest VM could possibly use this to escape into an outer VM or the host OS. (CVE-2018-12904) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly handle an error condition with a corrupted xfs image. An attacker could use this to construct a malicious xfs image that, when mounted, could cause a denial of service (system crash). (CVE-2018-13094) It was discovered that the Linux kernel did not properly handle setgid file creation when performed by a non-member of the group. A local attacker could use this to gain elevated privileges. (CVE-2018-13405) Silvio Cesare discovered that the generic VESA frame buffer driver in the Linux kernel contained an integer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-13406) Jakub Jirasek discovered that multiple use-after-free errors existed in the USB/IP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-5814) It was discovered that a race condition existed in the ARM Advanced Microcontroller Bus Architecture (AMBA) driver in the Linux kernel that could result in a double free. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-9415) It was discovered that an information leak existed in the generic SCSI driver in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-1000204). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description USN-3752-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 18.04 LTS for Ubuntu 16.04 LTS. It was discovered that, when attempting to handle an out-of-memory situation, a NULL pointer dereference could be triggered in the Linux kernel in some circumstances. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-1000200) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly validate meta-data information. An attacker could use this to construct a malicious xfs image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10323) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly validate xattr information. An attacker could use this to construct a malicious xfs image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10840) Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly keep meta-data information consistent in some situations. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10881) Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly handle corrupted meta data in some situations. An attacker could use this to specially craft an ext4 filesystem that caused a denial of service (system crash) when mounted. (CVE-2018-1093) Jann Horn discovered that the Linux kernel's implementation of random seed data reported that it was in a ready state before it had gathered sufficient entropy. An attacker could use this to expose sensitive information. (CVE-2018-1108) It was discovered that the procfs filesystem did not properly handle processes mapping some memory elements onto files. A local attacker could use this to block utilities that examine the procfs filesystem to report operating system state, such as ps(1). (CVE-2018-1120) Jann Horn discovered that the ext4 filesystem implementation in the Linux kernel did not properly keep xattr information consistent in some situations. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-11412) Piotr Gabriel Kosinski and Daniel Shapira discovered a stack-based buffer overflow in the CDROM driver implementation of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-11506) Shankara Pailoor discovered that a race condition existed in the socket handling code in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-12232) Shankara Pailoor discovered that the JFS filesystem implementation in the Linux kernel contained a buffer overflow when handling extended attributes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-12233) Felix Wilhelm discovered that the KVM implementation in the Linux kernel did not properly perform permission checks in some situations when nested virtualization is used. An attacker in a guest VM could possibly use this to escape into an outer VM or the host OS. (CVE-2018-12904) Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly handle an error condition with a corrupted xfs image. An attacker could use this to construct a malicious xfs image that, when mounted, could cause a denial of service (system crash). (CVE-2018-13094) It was discovered that the Linux kernel did not properly handle setgid file creation when performed by a non-member of the group. A local attacker could use this to gain elevated privileges. (CVE-2018-13405) Silvio Cesare discovered that the generic VESA frame buffer driver in the Linux kernel contained an integer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-13406) Jakub Jirasek discovered that multiple use-after-free errors existed in the USB/IP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-5814) It was discovered that a race condition existed in the ARM Advanced Microcontroller Bus Architecture (AMBA) driver in the Linux kernel that could result in a double free. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-9415) It was discovered that an information leak existed in the generic SCSI driver in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-1000204). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_SU-2019-0196-1.NASL
    description The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : 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-2018-12232: In net/socket.c in the there is 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's execution, leading to a NULL pointer dereference and system crash (bnc#1097593). CVE-2018-14625: A flaw was found where an attacker may be 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-2018-16862: 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-2018-16884: 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-2018-18397: 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-2018-19407: 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-2018-19854: 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-2018-19985: 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). 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.
