The version of AOS installed on the remote host is prior to 6.0.2. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.0.2 advisory.

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking     subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP     transfer-encoding request header in some circumstances leading to the possibility to request smuggling     when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if     the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding;
    and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1460-1 advisory.

    The openSUSE Leap 15.2 kernel was updated to receive various security and bugfixes.

    NOTE: This update was retracted due to a NFS regression.

    The following security bugs were fixed:

    - CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed 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 (bnc#1100416 bnc#1129735).
    - CVE-2021-33033: The Linux kernel had 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 (bnc#1186109 bnc#1188876).
    - CVE-2021-34556: 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 (bnc#1188983).
    - CVE-2021-35477: 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 did not     necessarily occur before a store operation that has an attacker-controlled value (bnc#1188985).
    - CVE-2021-3655: Missing size validations on inbound SCTP packets may have allowed the kernel to read     uninitialized memory (bnc#1188563 bnc#1192267).
    - CVE-2021-3715: Fixed a use-after-free in route4_change() in net/sched/cls_route.c (bsc#1190349).
    - CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->rf_conn_info object (bsc#1190067).
    - CVE-2021-3772: Invalid chunks may be used to remotely remove existing associations (bsc#1190351).
    - CVE-2021-3896: Fixed a array-index-out-bounds in detach_capi_ctr in drivers/isdn/capi/kcapi.c     (bsc#1191958).
    - CVE-2021-41864: prealloc_elems_and_freelist in kernel/bpf/stackmap.c allowed unprivileged users to     trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write (bnc#1191317).
    - CVE-2021-42008: The decode_data function in drivers/net/hamradio/6pack.c had a slab out-of-bounds write.
    Input from a process that has the CAP_NET_ADMIN capability can lead to root access (bnc#1191315).
    - CVE-2021-42252: An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c     where local attackers were able to access the Aspeed LPC control interface could overwrite memory in the     kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison     uses values that are not memory sizes (bnc#1190479).
    - CVE-2021-42739: The firewire subsystem had a buffer overflow related to drivers/media/firewire/firedtv-     avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bnc#1184673     bnc#1192036).
    - CVE-2021-42739: The firewire subsystem had a buffer overflow related to drivers/media/firewire/firedtv-     avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking     (bsc#1184673).
    - CVE-2021-43056: It allowed a malicious KVM guest to crash the host, when the host is running on Power8,     due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register     values (bnc#1192107).

  - A vulnerability was found in Linux Kernel where     refcount leak in llcp_sock_bind() causing     use-after-free which might lead to privilege     escalations.(CVE-2020-25670)

  - A vulnerability was found in Linux Kernel, where a     refcount leak in llcp_sock_connect() causing     use-after-free which might lead to privilege     escalations.(CVE-2020-25671)

  - A memory leak vulnerability was found in Linux kernel     in llcp_sock_connect(CVE-2020-25672)

  - 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)

  - An issue was discovered in fs/fuse/fuse_i.h in the     Linux kernel before 5.11.8. A 'stall on CPU' can occur     because a retry loop continually finds the same bad     inode, aka CID-775c5033a0d1.(CVE-2021-28950)

  - Use After Free vulnerability in nfc sockets in the     Linux Kernel before 5.12.4 allows local attackers to     elevate their privileges. In typical configurations,     the issue can only be triggered by a privileged local     user with the CAP_NET_RAW capability.(CVE-2021-23134)

  - An issue was discovered in the Linux kernel through     5.11.x. kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic,     leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from     kernel memory. Specifically, for sequences of pointer     arithmetic operations, the pointer modification     performed by the first operation is not correctly     accounted for when restricting subsequent     operations.(CVE-2021-29155)

  - The bpf verifier in the Linux kernel did not properly     handle mod32 destination register truncation when the     source register was known to be 0. A local attacker     with the ability to load bpf programs could use this     gain out-of-bounds reads in kernel memory leading to     information disclosure (kernel memory), and possibly     out-of-bounds writes that could potentially lead to     code execution. This issue was addressed in the     upstream kernel in commit 9b00f1b78809 ('bpf: Fix     truncation handling for mod32 dst reg wrt zero') and in     Linux stable kernels 5.11.2, 5.10.19, and     5.4.101.(CVE-2021-3444)

  - 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)

  - kernel/bpf/verifier.c in the Linux kernel through     5.12.1 performs undesirable speculative loads, leading     to disclosure of stack content via side-channel     attacks, aka CID-801c6058d14a. The specific concern is     not protecting the BPF stack area against speculative     loads. Also, the BPF stack can contain uninitialized     data that might represent sensitive information     previously operated on by the kernel.(CVE-2021-31829)

  - net/bluetooth/hci_request.c in the Linux kernel through     5.12.2 has a race condition for removal of the HCI     controller.(CVE-2021-32399)

  - In the Linux kernel before 5.12.4,     net/bluetooth/hci_event.c has a use-after-free when     destroying an hci_chan, aka CID-5c4c8c954409. This     leads to writing an arbitrary value.(CVE-2021-33034)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):kernel/bpf/verifier.c in     the Linux kernel through 5.12.7 enforces incorrect     limits for pointer arithmetic operations, aka     CID-bb01a1bba579. This can be abused to perform     out-of-bounds reads and writes in kernel memory,     leading to local privilege escalation to root. In     particular, there is a corner case where the off reg     causes a masking direction change, which then results     in an incorrect final aux->alu_limit.(CVE-2021-33200)A     vulnerability was found in Linux Kernel where refcount     leak in llcp_sock_bind() causing use-after-free which     might lead to privilege escalations.(CVE-2020-25670)A     vulnerability was found in Linux Kernel, where a     refcount leak in llcp_sock_connect() causing     use-after-free which might lead to privilege     escalations.(CVE-2020-25671)A memory leak vulnerability     was found in Linux kernel in     llcp_sock_connect(CVE-2020-25672)An out-of-bounds (OOB)     memory access flaw was found in fs/f2fs/ Node.c in the     f2fs module in the Linux kernel in versions before     5.12.0-rc4.

This leads to writing an arbitrary     value.(CVE-2021-33034)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)Use After     Free vulnerability in nfc sockets in the Linux Kernel     before 5.12.4 allows local attackers to elevate their     privileges. In typical configurations, the issue can     only be triggered by a privileged local user with the     CAP_NET_RAW capability.(CVE-2021-23134)An issue was     discovered in the Linux kernel before 5.9.
    arch/x86/kvm/svm/sev.c allows attackers to cause a     denial of service (soft lockup) by triggering     destruction of a large SEV VM (which requires     unregistering many encrypted regions), aka     CID-7be74942f184.(CVE-2020-36311)An issue was     discovered in the Linux kernel before 5.8.10.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In do_epoll_ctl and ep_loop_check_proc of eventpoll.c,     there is a possible use after free due to a logic     error. This could lead to local escalation of privilege     with no additional execution privileges needed. User     interaction is not needed for     exploitation.(CVE-2020-0466)

  - fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8,     when there is an NFS export of a subdirectory of a     filesystem, allows remote attackers to traverse to     other parts of the filesystem via READDIRPLUS. NOTE:
    some parties argue that such a subdirectory export is     not intended to prevent this attack see also the     exports(5) no_subtree_check default     behavior.(CVE-2021-3178)

  - An issue was discovered in the Linux kernel through     5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an     iSCSI transport is registered with the iSCSI subsystem,     the transport's handle is available to unprivileged     users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)

  - An issue was discovered in the Linux kernel through     5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged     user to craft Netlink messages.(CVE-2021-27364)

  - A race condition was found in the Linux kernels     implementation of the floppy disk drive controller     driver software. The impact of this issue is lessened     by the fact that the default permissions on the floppy     device (/dev/fd0) are restricted to root. If the     permissions on the device have changed the impact     changes greatly. In the default configuration root (or     equivalent) permissions are required to attack this     flaw.(CVE-2021-20261)

  - In fs/ocfs2/cluster/nodemanager.c in the Linux kernel     before 4.15, local users can cause a denial of service     (NULL pointer dereference and BUG) because a required     mutex is not used.(CVE-2017-18216)

  - The omninet_open function in     drivers/usb/serial/omninet.c in the Linux kernel before     4.10.4 allows local users to cause a denial of service     (tty exhaustion) by leveraging reference count     mishandling.(CVE-2017-8925)

  - 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)

  - A flaw was found in the JFS filesystem code in the     Linux Kernel which allows a local attacker with the     ability to set extended attributes to panic the system,     causing memory corruption or escalating privileges. The     highest threat from this vulnerability is to     confidentiality, integrity, as well as system     availability.(CVE-2020-27815)

  - An out-of-bounds (OOB) memory access flaw was found in     x25_bind in net/x25/af_x25.c in the Linux kernel     version v5.12-rc5. A bounds check failure allows a     local attacker with a user account on the system 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     confidentiality, integrity, as well as system     availability.(CVE-2020-35519)

  - There is a flaw reported in the Linux kernel in     versions before 5.9 in     drivers/gpu/drm/nouveau/nouveau_sgdma.c in     nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The     issue results from the lack of validating the existence     of an object prior to performing operations on the     object. An attacker with a local account with a root     privilege, can leverage this vulnerability to escalate     privileges and execute code in the context of the     kernel.(CVE-2021-20292)

  - In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux     kernel through 5.11.8, the RPA PCI Hotplug driver has a     user-tolerable buffer overflow when writing a new     device name to the driver from userspace, allowing     userspace to write data to the kernel stack frame     directly. This occurs because add_slot_store and     remove_slot_store mishandle drc_name '\0' termination,     aka CID-cc7a0bb058b8.(CVE-2021-28972)

  - A race condition was discovered in get_old_root in     fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It     allows attackers to cause a denial of service (BUG)     because of a lack of locking on an extent buffer before     a cloning operation, aka     CID-dbcc7d57bffc.(CVE-2021-28964)

  - An issue was discovered in the Linux kernel before     5.11.7. usbip_sockfd_store in     drivers/usb/usbip/stub_dev.c allows attackers to cause     a denial of service (GPF) because the stub-up sequence     has race conditions during an update of the local and     shared status, aka CID-9380afd6df70.(CVE-2021-29265)

  - BPF JIT compilers in the Linux kernel through 5.11.12     have incorrect computation of branch displacements,     allowing them to execute arbitrary code within the     kernel context. This affects     arch/x86/net/bpf_jit_comp.c and     arch/x86/net/bpf_jit_comp32.c.(CVE-2021-29154)

  - The KVM implementation in the Linux kernel through     4.14.7 allows attackers to obtain potentially sensitive     information from kernel memory, aka a write_mmio     stack-based out-of-bounds read, related to     arch/x86/kvm/x86.c and     include/trace/events/kvm.h.(CVE-2017-17741)

  - An issue was discovered in the Linux kernel before     5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak     for large arguments, aka     CID-fb18802a338b.(CVE-2021-30002)

  - An issue was discovered in the Linux kernel through     4.17.10. There is an invalid pointer dereference in
    __del_reloc_root() in fs/btrfs/relocation.c when     mounting a crafted btrfs image, related to removing     reloc rb_trees when reloc control has not been     initialized.(CVE-2018-14609)

  - An issue was discovered in     fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel     through 4.17.3. A denial of service (memory corruption     and BUG) can occur for a corrupted xfs image upon     encountering an inode that is in extent format, but has     more extents than fit in the inode     fork.(CVE-2018-13095)

  - The vmw_gb_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel through 4.10.7 does not validate certain levels     data, which allows local users to cause a denial of     service (system hang) via a crafted ioctl call for a     /dev/dri/renderD* device.(CVE-2017-7346)

  - The klsi_105_get_line_state function in     drivers/usb/serial/kl5kusb105.c in the Linux kernel     before 4.9.5 places uninitialized heap-memory contents     into a log entry upon a failure to read the line     status, which allows local users to obtain sensitive     information by reading the log.(CVE-2017-5549)

  - An integer overflow in the uvesafb_setcmap function in     drivers/video/fbdev/uvesafb.c in the Linux kernel     before 4.17.4 could result in local attackers being     able to crash the kernel or potentially elevate     privileges because kmalloc_array is not     used.(CVE-2018-13406)

  - In the Linux kernel before version 4.12, Kerberos 5     tickets decoded when using the RXRPC keys incorrectly     assumes the size of a field. This could lead to the     size-remaining variable wrapping and the data pointer     going over the end of the buffer. This could possibly     lead to memory corruption and possible privilege     escalation.(CVE-2017-7482)

  - drivers/net/usb/rtl8150.c in the Linux kernel 4.9.x     before 4.9.11 interacts incorrectly with the     CONFIG_VMAP_STACK option, which allows local users to     cause a denial of service (system crash or memory     corruption) or possibly have unspecified other impact     by leveraging use of more than one virtual page for a     DMA scatterlist.(CVE-2017-8069)

  - An issue was discovered in the Linux kernel through     5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can     exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI,     and has a length up to the maximum length of a Netlink     message.(CVE-2021-27365)

  - A flaw was found in the Nosy driver in the Linux     kernel. This issue allows a device to be inserted twice     into a doubly-linked list, leading to a use-after-free     when one of these devices is removed. The highest     threat from this vulnerability is to confidentiality,     integrity, as well as system availability. Versions     before kernel 5.12-rc6 are affected(CVE-2021-3483)

  - An issue was discovered in the FUSE filesystem     implementation in the Linux kernel before 5.10.6, aka     CID-5d069dbe8aaf. fuse_do_getattr() calls     make_bad_inode() in inappropriate situations, causing a     system crash. NOTE: the original fix for this     vulnerability was incomplete, and its incompleteness is     tracked as CVE-2021-28950.(CVE-2020-36322)

  - 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)

  - A vulnerability was found in Linux Kernel, where a     refcount leak in llcp_sock_connect() causing     use-after-free which might lead to privilege     escalations.(CVE-2020-25671)

  - A vulnerability was found in Linux Kernel where     refcount leak in llcp_sock_bind() causing     use-after-free which might lead to privilege     escalations.(CVE-2020-25670)

  - A memory leak vulnerability was found in Linux kernel     in llcp_sock_connect(CVE-2020-25672)

  - 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)

  - Use After Free vulnerability in nfc sockets in the     Linux Kernel before 5.12.4 allows local attackers to     elevate their privileges. In typical configurations,     the issue can only be triggered by a privileged local     user with the CAP_NET_RAW capability.(CVE-2021-23134)

  - A flaw use-after-free in function     hci_sock_bound_ioctl() of the Linux kernel HCI     subsystem was found in the way user detaches bluetooth     dongle or other way triggers unregister bluetooth     device event. A local user could use this flaw to crash     the system or escalate their privileges on the     system.(CVE-2021-3573)

  - An issue was discovered in the Linux kernel through     5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute     code in the kernel, aka     CID-34b1a1ce1458.(CVE-2021-3347)

  - A vulnerability was found in Linux kernel where     non-blocking socket in llcp_sock_connect() leads to     leak and eventually hanging-up the     system.(CVE-2020-25673)

  - In all Qualcomm products with Android releases from CAF     using the Linux kernel, during DMA allocation, due to     wrong data type of size, allocation size gets truncated     which makes allocation succeed when it should     fail.(CVE-2017-9725)

  - A flaw double-free memory corruption in the Linux     kernel HCI device initialization subsystem was found in     the way user attach malicious HCI TTY Bluetooth device.
    A local user could use this flaw to crash the system.
    This flaw affects all the Linux kernel versions     starting from 3.13.(CVE-2021-3564)

  - A flaw was found in the CAN BCM networking protocol in     the Linux kernel, where a local attacker can abuse a     flaw in the CAN subsystem to corrupt memory, crash the     system or escalate privileges.(CVE-2021-3609)

  - The ip6gre_err function in net/ipv6/ip6_gre.c in the     Linux kernel allows remote attackers to have     unspecified impact via vectors involving GRE flags in     an IPv6 packet, which trigger an out-of-bounds     access.(CVE-2017-5897)

  - An Out-of-Bounds Read was discovered in     arch/arm/mach-footbridge/personal-pci.c in the Linux     kernel through 5.12.11 because of the lack of a check     for a value that shouldn't be negative, e.g., access to     element -2 of an array, aka     CID-298a58e165e4.(CVE-2021-32078)

  - In the Linux kernel before 4.20.8,     kvm_ioctl_create_device in virt/kvm/kvm_main.c     mishandles reference counting because of a race     condition, leading to a use-after-free.(CVE-2019-6974)

  - In uvc_scan_chain_forward of uvc_driver.c, there is a     possible linked list corruption due to an unusual root     cause. This could lead to local escalation of privilege     in the kernel with no additional execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2020-0404)

  - In create_pinctrl of core.c, there is a possible out of     bounds read due to a use after free. This could lead to     local information disclosure with no additional     execution privileges needed. User interaction is not     needed for exploitation.(CVE-2020-0427)
