The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device.

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5671 advisory.

  - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable     to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source,     the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver     receives the firmware event frame from the host, the appropriate handler is called. This frame validation     can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event     frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi     packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
    More typically, this vulnerability will result in denial-of-service conditions. (CVE-2019-9503)

  - In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/hid/usbhid/hiddev.c driver, aka CID-9c09b214f30e. (CVE-2019-19527)

  - In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a     malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95. This affects drivers/hid/hid-     axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-     tmff.c, and drivers/hid/hid-zpff.c. (CVE-2019-19532)

  - The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel     through 4.10.5 does not check for a zero value of certain levels data, which allows local users to cause a     denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a     /dev/dri/renderD* device. (CVE-2017-7261)

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

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

  - The perf_cpu_time_max_percent_handler function in     kernel/events/core.c in the Linux kernel before 4.11     allows local users to cause a denial of service     (integer overflow) or possibly have unspecified other     impact via a large value, as demonstrated by an     incorrect sample-rate calculation.(CVE-2017-18255)

  - In the Linux kernel before 4.13.5, a local user could     create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of     service.(CVE-2017-18270)

  - The timer_create syscall implementation in     kernel/time/posix-timers.c in the Linux kernel doesn't     properly validate the sigevent-i1/4zsigev_notify field,     which leads to out-of-bounds access in the show_timer     function.(CVE-2017-18344)

  - arch/x86/kvm/emulate.c in the Linux kernel through     4.9.3 allows local users to obtain sensitive     information from kernel memory or cause a denial of     service (use-after-free) via a crafted application that     leverages instruction emulation for fxrstor, fxsave,     sgdt, and sidt.(CVE-2017-2584)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization(nVMX) feature     enabled(nested=1), is vulnerable to host memory leakage     issue. It could occur while emulating VMXON instruction     in 'handle_vmon'. An L1 guest user could use this flaw     to leak host memory potentially resulting in     DoS.(CVE-2017-2596)

  - A race condition flaw was found in the N_HLDC Linux     kernel driver when accessing n_hdlc.tbuf list that can     lead to double free. A local, unprivileged user able to     set the HDLC line discipline on the tty device could     use this flaw to increase their privileges on the     system.(CVE-2017-2636)

  - A flaw was found that can be triggered in     keyring_search_iterator in keyring.c if type-i1/4zmatch     is NULL. A local user could use this flaw to crash the     system or, potentially, escalate their     privileges.(CVE-2017-2647)

  - A race condition leading to a NULL pointer dereference     was found in the Linux kernel's Link Layer Control     implementation. A local attacker with access to ping     sockets could use this flaw to crash the     system.(CVE-2017-2671)

  - A vulnerability was found in the Linux kernel in     'tmpfs' file system. When file permissions are modified     via 'chmod' and the user is not in the owning group or     capable of CAP_FSETID, the setgid bit is cleared in     inode_change_ok(). Setting a POSIX ACL via 'setxattr'     sets the file permissions as well as the new ACL, but     doesn't clear the setgid bit in a similar way this     allows to bypass the check in 'chmod'.(CVE-2017-5551)

  - The do_shmat function in ipc/shm.c in the Linux kernel,     through 4.9.12, does not restrict the address     calculated by a certain rounding operation. This allows     privileged local users to map page zero and,     consequently, bypass a protection mechanism that exists     for the mmap system call. This is possible by making     crafted shmget and shmat system calls in a privileged     context.(CVE-2017-5669)

  - A vulnerability was found in the Linux kernel where     having malicious IP options present would cause the     ipv4_pktinfo_prepare() function to drop/free the dst.
    This could result in a system crash or possible     privilege escalation.(CVE-2017-5970)

  - 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-2017-5986)

  - It was found that the original fix for CVE-2016-6786     was incomplete. There exist a race between two     concurrent sys_perf_event_open() calls when both try     and move the same pre-existing software group into a     hardware context.(CVE-2017-6001)

  - A use-after-free flaw was found in the way the Linux     kernel's Datagram Congestion Control Protocol (DCCP)     implementation freed SKB (socket buffer) resources for     a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO     option is set on the socket. A local, unprivileged user     could use this flaw to alter the kernel memory,     allowing them to escalate their privileges on the     system.(CVE-2017-6074)

  - A flaw was found in the Linux kernel's handling of     packets with the URG flag. Applications using the     splice() and tcp_splice_read() functionality could     allow a remote attacker to force the kernel to enter a     condition in which it could loop     indefinitely.(CVE-2017-6214)

  - The hashbin_delete function in net/irda/irqueue.c in     the Linux kernel improperly manages lock dropping,     which allows local users to cause a denial of service     (deadlock) via crafted operations on IrDA     devices.(CVE-2017-6348)

  - It was found that the code in net/sctp/socket.c in the     Linux kernel through 4.10.1 does not properly restrict     association peel-off operations during certain wait     states, which allows local users to cause a denial of     service (invalid unlock and double free) via a     multithreaded application. This vulnerability was     introduced by CVE-2017-5986 fix (commit     2dcab5984841).(CVE-2017-6353)

  - The keyring_search_aux function in     security/keys/keyring.c in the Linux kernel allows     local users to cause a denial of service via a     request_key system call for the 'dead' key     type.(CVE-2017-6951)

  - The sg_ioctl function in drivers/scsi/sg.c in the Linux     kernel allows local users to cause a denial of service     (stack-based buffer overflow) or possibly have     unspecified other impacts via a large command size in     an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds     write access in the sg_write function.(CVE-2017-7187)

  - In was found that in the Linux kernel, in     vmw_surface_define_ioctl() function in     'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file, a     'num_sizes' parameter is assigned a user-controlled     value which is not checked if it is zero. This is used     in a call to kmalloc() and later leads to dereferencing     ZERO_SIZE_PTR, which in turn leads to a GPF and     possibly to a kernel panic.(CVE-2017-7261)

  - An out-of-bounds write vulnerability was found in the     Linux kernel's vmw_surface_define_ioctl() function, in     the 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file. Due     to the nature of the flaw, privilege escalation cannot     be fully ruled out, although we believe it is     unlikely.(CVE-2017-7294)

  - It was found that the packet_set_ring() function of the     Linux kernel's networking implementation did not     properly validate certain block-size data. A local     attacker with CAP_NET_RAW capability could use this     flaw to trigger a buffer overflow, resulting in the     crash of the system. Due to the nature of the flaw,     privilege escalation cannot be fully ruled     out.(CVE-2017-7308)

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The hid_input_field() function in     'drivers/hid/hid-core.c' in the Linux kernel before 4.6     allows physically proximate attackers to obtain     sensitive information from kernel memory or cause a     denial of service (out-of-bounds read) by connecting a     device.(CVE-2016-7915i1/4%0

  - The Linux kernel, before version 4.14.2, is vulnerable     to a deadlock caused by     fs/ocfs2/file.c:ocfs2_setattr(), as the function does     not wait for DIO requests before locking the inode.
    This can be exploited by local users to cause a     subsequent denial of service.(CVE-2017-18204i1/4%0

  - The vmw_gb_surface_define_ioctl function (accessible     via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel through 4.11.4 defines a backup_handle variable     but does not give it an initial value. If one attempts     to create a GB surface, with a previously allocated DMA     buffer to be used as a backup buffer, the backup_handle     variable does not get written to and is then later     returned to user space, allowing local users to obtain     sensitive information from uninitialized kernel memory     via a crafted ioctl call.(CVE-2017-9605i1/4%0

  - Use-after-free vulnerability in the nfqnl_zcopy     function in net/netfilter/nfnetlink_queue_core.c in the     Linux kernel through 3.13.6 allows attackers to obtain     sensitive information from kernel memory by leveraging     the absence of a certain orphaning operation. NOTE: the     affected code was moved to the skb_zerocopy function in     net/core/skbuff.c before the vulnerability was     announced.(CVE-2014-2568i1/4%0

  - It was found that the Linux kernel's ISO file system     implementation did not correctly limit the traversal of     Rock Ridge extension Continuation Entries (CE). An     attacker with physical access to the system could use     this flaw to trigger an infinite loop in the kernel,     resulting in a denial of service.(CVE-2014-9420i1/4%0

  - An integer overflow vulnerability was found in the     ring_buffer_resize() calculations in which a privileged     user can adjust the size of the ringbuffer message     size. These calculations can create an issue where the     kernel memory allocator will not allocate the correct     count of pages yet expect them to be usable. This can     lead to the ftrace() output to appear to corrupt kernel     memory and possibly be used for privileged escalation     or more likely kernel panic.(CVE-2016-9754i1/4%0

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9730i1/4%0

  - In was found that in the Linux kernel, in     vmw_surface_define_ioctl() function in     'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file, a     'num_sizes' parameter is assigned a user-controlled     value which is not checked if it is zero. This is used     in a call to kmalloc() and later leads to dereferencing     ZERO_SIZE_PTR, which in turn leads to a GPF and     possibly to a kernel panic.(CVE-2017-7261i1/4%0

  - A race condition flaw was found in the way the Linux     kernel keys management subsystem performed key garbage     collection. A local attacker could attempt accessing a     key while it was being garbage collected, which would     cause the system to crash.(CVE-2014-9529i1/4%0

  - A flaw was found in the Linux kernel's implementation     of i8042 serial ports. An attacker could cause a kernel     panic if they are able to add and remove devices as the     module is loaded.(CVE-2017-18079i1/4%0

  - drivers/hid/hid-pl.c in the Human Interface Device     (HID) subsystem in the Linux kernel through 3.11, when     CONFIG_HID_PANTHERLORD is enabled, allows physically     proximate attackers to cause a denial of service     (heap-based out-of-bounds write) via a crafted     device.(CVE-2013-2892i1/4%0

  - A divide-by-zero vulnerability was found in a way the     kernel processes TCP connections. The error can occur     if a connection starts another cwnd reduction phase by     setting tp-i1/4zprior_cwnd to the current cwnd (0) in     tcp_init_cwnd_reduction(). A remote, unauthenticated     attacker could use this flaw to crash the kernel     (denial of service).(CVE-2016-2070i1/4%0

  - The adjust_branches function in kernel/bpf/verifier.c     in the Linux kernel before 4.5 does not consider the     delta in the backward-jump case, which allows local     users to obtain sensitive information from kernel     memory by creating a packet filter and then loading     crafted BPF instructions.(CVE-2016-2383i1/4%0

  - System using the infiniband support module ib_srpt were     vulnerable to a denial of service by system crash by a     local attacker who is able to abort writes to a device     using this initiator.(CVE-2016-6327i1/4%0

  - A security flaw was found in the Linux kernel in the     mark_source_chains() function in     'net/ipv4/netfilter/ip_tables.c'. It is possible for a     user-supplied 'ipt_entry' structure to have a large     'next_offset' field. This field is not bounds checked     prior to writing to a counter value at the supplied     offset.(CVE-2016-3134i1/4%0

  - An out-of-bounds access issue was discovered in     yurex_read() in drivers/usb/misc/yurex.c in the Linux     kernel. A local attacker could use user access     read/writes with incorrect bounds checking in the yurex     USB driver to crash the kernel or potentially escalate     privileges.(CVE-2018-16276i1/4%0

  - drivers/media/v4l2-core/videobuf2-v4l2.c in the Linux     kernel before 4.5.3 allows local users to cause a     denial of service (kernel memory write operation) or     possibly have unspecified other impact via a crafted     number of planes in a VIDIOC_DQBUF ioctl     call.(CVE-2016-4568i1/4%0

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or have other impacts.

CVE-2016-2188

Ralf Spenneberg of OpenSource Security reported that the iowarrior device driver did not sufficiently validate USB descriptors. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash).

CVE-2016-9604

It was discovered that the keyring subsystem allowed a process to set a special internal keyring as its session keyring. The security impact in this version of the kernel is unknown.

CVE-2016-10200

Baozeng Ding and Andrey Konovalov reported a race condition in the L2TP implementation which could corrupt its table of bound sockets. A local user could use this to cause a denial of service (crash) or possibly for privilege escalation.

CVE-2017-2647 / CVE-2017-6951

idl3r reported that the keyring subsystem would allow a process to search for 'dead' keys, causing a NULL pointer dereference. A local user could use this to cause a denial of service (crash).

CVE-2017-2671

Daniel Jiang discovered a race condition in the ping socket implementation. A local user with access to ping sockets could use this to cause a denial of service (crash) or possibly for privilege escalation. This feature is not accessible to any users by default.

CVE-2017-5967

Xing Gao reported that the /proc/timer_list file showed information about all processes, not considering PID namespaces. If timer debugging was enabled by a privileged user, this leaked information to processes contained in PID namespaces.

CVE-2017-5970

Andrey Konovalov discovered a denial of service flaw in the IPv4 networking code. This can be triggered by a local or remote attacker if a local UDP or raw socket has the IP_RETOPTS option enabled.

CVE-2017-7184

Chaitin Security Research Lab discovered that the net xfrm subsystem did not sufficiently validate replay state parameters, allowing a heap buffer overflow. This can be used by a local user with the CAP_NET_ADMIN capability for privilege escalation.

CVE-2017-7261

Vladis Dronov and Murray McAllister reported that the vmwgfx driver did not sufficiently validate rendering surface parameters. In a VMware guest, this can be used by a local user to cause a denial of service (crash).

CVE-2017-7273

Benoit Camredon reported that the hid-cypress driver did not sufficiently validate HID reports. This possibly allowed a physically present user with a specially designed USB device to cause a denial of service (crash).

CVE-2017-7294

Li Qiang reported that the vmwgfx driver did not sufficiently validate rendering surface parameters. In a VMware guest, this can be used by a local user to cause a denial of service (crash) or possibly for privilege escalation.

CVE-2017-7308

Andrey Konovalov reported that the packet socket (AF_PACKET) implementation did not sufficiently validate buffer parameters. This can be used by a local user with the CAP_NET_RAW capability for privilege escalation.

CVE-2017-7472

Eric Biggers reported that the keyring subsystem allowed a thread to create new thread keyrings repeatedly, causing a memory leak. This can be used by a local user to cause a denial of service (memory exhaustion).

CVE-2017-7616

Chris Salls reported an information leak in the 32-bit big-endian compatibility implementations of set_mempolicy() and mbind(). This does not affect any architecture supported in Debian 7 LTS.

CVE-2017-7618

Sabrina Dubroca reported that the cryptographic hash subsystem does not correctly handle submission of unaligned data to a device that is already busy, resulting in infinite recursion. On some systems this can be used by local users to cause a denial of service (crash).

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.88-1. This version also includes bug fixes from upstream version 3.2.88, and fixes some older security issues in the keyring, packet socket and cryptographic hash subsystems that do not have CVE IDs.

For Debian 8 'Jessie', most of these problems have been fixed in version 3.16.43-1 which will be part of the next point release.
