Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3935-1 advisory.

- kernel/bpf/verifier.c in the Linux kernel through 4.14.8 ignores unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service. (CVE-2017-17862)

- kernel/bpf/verifier.c in the Linux kernel through 4.14.8 mishandles states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allows local users to obtain potentially sensitive address information, aka a pointer leak. (CVE-2017-17864)

- The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID. (CVE-2018-13405)

- A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested(=1) virtualization is enabled. In nested_get_vmcs12_pages(), in case of an error while processing posted interrupt address, it unmaps the 'pi_desc_page' without resetting 'pi_desc' descriptor address, which is later used in pi_test_and_clear_on(). A guest user/process could use this flaw to crash the host kernel resulting in DoS or potentially gain privileged access to a system. Kernel versions before 4.14.91 and before 4.19.13 are vulnerable. (CVE-2018-16882)

- In l2tp_session_delete and related functions of l2tp_core.c, there is possible memory corruption due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-152735806 (CVE-2020-0429)

- An issue was discovered in xfs_agf_verify in fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through 5.6.10. Attackers may trigger a sync of excessive duration via an XFS v5 image with crafted metadata, aka CID-d0c7feaf8767. (CVE-2020-12655)

- An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote user to crash the system, causing a denial of service. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-14305)

- u'Specifically timed and handcrafted traffic can cause internal errors in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure over the air for a discrete set of traffic' in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wearables, Snapdragon Wired Infrastructure and Networking in APQ8053, IPQ4019, IPQ8064, MSM8909W, MSM8996AU, QCA9531, QCN5502, QCS405, SDX20, SM6150, SM7150 (CVE-2020-3702)

- IBM Power9 (AIX 7.1, 7.2, and VIOS 3.1) processors could allow a local user to obtain sensitive information from the data in the L1 cache under extenuating circumstances. IBM X-Force ID: 189296. (CVE-2020-4788)

- A flaw was found in the way memory resources were freed in the unix_stream_recvmsg function in the Linux kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by exhausting available memory. The highest threat from this vulnerability is to system availability. (CVE-2021-20265)

- An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi- device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. (CVE-2021-31916)

- The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to writing an arbitrary value. (CVE-2021-33033)

- In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack. (CVE-2021-34556)

- ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2021-42739. Reason: This candidate is a reservation duplicate of CVE-2021-42739. Notes: All CVE users should reference CVE-2021-42739 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage. (CVE-2021-3542)

- In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value. (CVE-2021-35477)

- A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to 5.14-rc7. (CVE-2021-3653)

- A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

- kernel: NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c (CVE-2021-3659)

- A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was found in the way user uses trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service. (CVE-2021-3679)

- kernel: use-after-free in route4_change() in net/sched/cls_route.c (CVE-2021-3715)

- hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free. (CVE-2021-37159)

- kernel: overlayfs: Mounting overlayfs inside an unprivileged user namespace can reveal files (CVE-2021-3732)

- A flaw was found in the Linux kernel. When reusing a socket with an attached dccps_hc_tx_ccid as a listener, the socket will be used after being released leading to denial of service (DoS) or a potential code execution. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-16119) (CVE-2021-3753)

- arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)

- ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE: the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the length validation was added solely for robustness in the face of anomalous host OS behavior. (CVE-2021-38160)

- arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access permissions of a shadow page, leading to a missing guest protection page fault. (CVE-2021-38198)

- drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain situations. (CVE-2021-38204)

- ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2021-43389. Reason: This candidate is a reservation duplicate of CVE-2021-43389. Notes: All CVE users should reference CVE-2021-43389 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage. (CVE-2021-3896)

- A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the Linux kernel through 5.13.13. (CVE-2021-40490)

- The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access. (CVE-2021-42008)

- The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking. (CVE-2021-42739)

- An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

    kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store
    operation does not necessarily occur before a store operation that has an attacker-controlled value.
    (CVE-2021-35477)

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when
    processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested
    guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to
    enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest
    would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak
    of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to
    5.14-rc7. (CVE-2021-3653)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on
    inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - kernel: NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c (CVE-2021-3659)

  - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was
    found in the way user uses trace ring buffer in a specific way. Only privileged local users (with
    CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
    (CVE-2021-3679)

  - kernel: use-after-free in route4_change() in net/sched/cls_route.c (CVE-2021-3715)

  - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev
    without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.
    (CVE-2021-37159)

  - kernel: overlayfs: Mounting overlayfs inside an unprivileged user namespace can reveal files
    (CVE-2021-3732)

  - A flaw was found in the Linux kernel. When reusing a socket with an attached dccps_hc_tx_ccid as a
    listener, the socket will be used after being released leading to denial of service (DoS) or a potential
    code execution. The highest threat from this vulnerability is to data confidentiality and integrity as
    well as system availability. (CVE-2020-16119) (CVE-2021-3753)

  - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest
    OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)

  - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss
    can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the
    length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

  - arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access
    permissions of a shadow page, leading to a missing guest protection page fault. (CVE-2021-38198)

  - drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to
    cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain
    situations. (CVE-2021-38204)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2021-43389. Reason: This candidate is a
    reservation duplicate of CVE-2021-43389. Notes: All CVE users should reference CVE-2021-43389 instead of
    this candidate. All references and descriptions in this candidate have been removed to prevent accidental
    usage. (CVE-2021-3896)

  - A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in
    the Linux kernel through 5.13.13. (CVE-2021-40490)

  - The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab
    out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.
    (CVE-2021-42008)

  - The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to
    drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt
    mishandles bounds checking. (CVE-2021-42739)

  - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in
    the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
