The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2854 advisory.

  - A flaw was found in the Linux kernel's NFS41+ subsystem. 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. (CVE-2018-16884)

  - An issue was discovered in the Linux kernel before 5.0.4. There is a use-after-free upon attempted read     access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c,     drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c. (CVE-2019-11811)

  - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when     hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)

  - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel     through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.
    (CVE-2019-18808)

  - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through     5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     crypto_report_alg() failures, aka CID-ffdde5932042. (CVE-2019-19062)

  - The Linux kernel before 5.4.2 mishandles ext4_expand_extra_isize, as demonstrated by use-after-free errors     in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c, aka     CID-4ea99936a163. (CVE-2019-19767)

  - In the Linux kernel before 5.4.12, drivers/input/input.c has out-of-bounds writes via a crafted keycode     table, as demonstrated by input_set_keycode, aka CID-cb222aed03d7. (CVE-2019-20636)

  - In the Android kernel in the video driver there is a use after free due to a race condition. This could     lead to local escalation of privilege with no additional execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9458)

  - A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an     attacker with local access to crash the system. (CVE-2020-10720)

  - An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-     based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-     aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the     issue is a bug in parsing mount options which can only be specified by a privileged user, so triggering     the bug does not grant any powers not already held. (CVE-2020-11565)

  - The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory     space. (CVE-2020-12888)

  - KVM in the Linux kernel on Power8 processors has a conflicting use of HSTATE_HOST_R1 to store r1 state in     kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an     attacker with the ability run code in kernel space of a guest VM can cause the host kernel to panic. There     were two commits that, according to the reporter, introduced the vulnerability: f024ee098476 (KVM: PPC:
    Book3S HV: Pull out TM state save/restore into separate procedures) 87a11bb6a7f7 (KVM: PPC: Book3S HV:
    Work around XER[SO] bug in fake suspend mode) The former landed in 4.8, the latter in 4.17. This was     fixed without realizing the impact in 4.18 with the following three commits, though it's believed the     first is the only strictly necessary commit: 6f597c6b63b6 (KVM: PPC: Book3S PR: Add guest MSR parameter     for kvmppc_save_tm()/kvmppc_restore_tm()) 7b0e827c6970 (KVM: PPC: Book3S HV: Factor fake-suspend     handling out of kvmppc_save/restore_tm) 009c872a8bc4 (KVM: PPC: Book3S PR: Move     kvmppc_save_tm/kvmppc_restore_tm to separate file) (CVE-2020-8834)

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

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

  - A flaw was found in the Linux kernel's implementation     of GRO. This flaw allows an attacker with local access     to crash the system.(CVE-2020-10720)

  - A NULL pointer dereference flaw was found in the Linux     kernel's SELinux subsystem. This flaw occurs while     importing the Commercial IP Security Option (CIPSO)     protocol's category bitmap into the SELinux extensible     bitmap via the' ebitmap_netlbl_import' routine. While     processing the CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of     service.(CVE-2020-10711)

  - A signal access-control issue was discovered in the     Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32     bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process     can send an arbitrary signal to a parent process in a     different security domain. Exploitation limitations     include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where     signals to a parent process present a substantial     operational threat.(CVE-2020-12826)

  - An issue was discovered in the Linux kernel before     5.4.17. drivers/spi/spi-dw.c allows attackers to cause     a panic via concurrent calls to dw_spi_irq and     dw_spi_transfer_one, aka     CID-19b61392c5a8.(CVE-2020-12769)

  - An issue was discovered in the Linux kernel through     5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka     CID-83c6f2390040.(CVE-2020-12770)

  - An issue was discovered in the Linux kernel through     5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c     has a deadlock if a coalescing operation     fails.(CVE-2020-12771)

  - The __mptctl_ioctl function in     drivers/message/fusion/mptctl.c in the Linux kernel     before 5.4.14 allows local users to hold an incorrect     lock during the ioctl operation and trigger a race     condition, i.e., a 'double fetch' vulnerability, aka     CID-28d76df18f0a. NOTE: the vendor states 'The security     impact of this bug is not as bad as it could have been     because these operations are all privileged and root     already has enormous destructive     power.'(CVE-2020-12652)

  - 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)

  - A pivot_root race condition in fs amespace.c in the     Linux kernel 4.4.x before 4.4.221, 4.9.x before     4.9.221, 4.14.x before 4.14.178, 4.19.x before     4.19.119, and 5.x before 5.3 allows local users to     cause a denial of service (panic) by corrupting a     mountpoint reference counter.(CVE-2020-12114)

  - An issue was discovered in the Linux kernel before     5.6.5. There is a use-after-free in block/bfq-iosched.c     related to bfq_idle_slice_timer_body.(CVE-2020-12657)

  - usb_sg_cancel in drivers/usb/core/message.c in the     Linux kernel before 5.6.8 has a use-after-free because     a transfer occurs without a reference, aka     CID-056ad39ee925.(CVE-2020-12464)

  - An issue was found in Linux kernel before 5.5.4. The     mwifiex_cmd_append_vsie_tlv() function in drivers     et/wireless/marvell/mwifiex/scan.c allows local users     to gain privileges or cause a denial of service because     of an incorrect memcpy and buffer overflow, aka     CID-b70261a288ea.(CVE-2020-12653)

  - gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c     in the rpcsec_gss_krb5 implementation in the Linux     kernel through 5.6.10 lacks certain domain_release     calls, leading to a memory leak.(CVE-2020-12656)

  - An issue was discovered in the Linux kernel before     5.6.7. xdp_umem_reg in net/xdp/xdp_umem.c has an     out-of-bounds write (by a user with the CAP_NET_ADMIN     capability) because of a lack of headroom     validation.(CVE-2020-12659)

  - An array overflow was discovered in mt76_add_fragment     in drivers et/wireless/mediatek/mt76/dma.c in the Linux     kernel before 5.5.10, aka CID-b102f0c522cf. An     oversized packet with too many rx fragments can corrupt     memory of adjacent pages.(CVE-2020-12465)

  - An issue was found in Linux kernel before 5.5.4.
    mwifiex_ret_wmm_get_status() in drivers     et/wireless/marvell/mwifiex/wmm.c allows a remote AP to     trigger a heap-based buffer overflow because of an     incorrect memcpy, aka CID-3a9b153c5591.(CVE-2020-12654)

  - In the Linux kernel through 5.6.7 on the s390 platform,     code execution may occur because of a race condition,     as demonstrated by code in enable_sacf_uaccess in     arch/s390/lib/uaccess.c that fails to protect against a     concurrent page table upgrade, aka CID-3f777e19d171. A     crash could also occur.(CVE-2020-11884)

  - relay_open in kernel/relay.c in the Linux kernel     through 5.4.1 allows local users to cause a denial of     service (such as relay blockage) by triggering a NULL     alloc_percpu result.(CVE-2019-19462)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs     filesystem image, performing some operations, and     unmounting can lead to a use-after-free in     btrfs_queue_work in     fs/btrfs/async-thread.c.(CVE-2019-19377)

  - In the Linux kernel before 5.5.8, get_raw_socket in     drivers/vhost et.c lacks validation of an sk_family     field, which might allow attackers to trigger kernel     stack corruption via crafted system     calls.(CVE-2020-10942)

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an     attacker with local access to crash the system. (CVE-2020-10720)

Note that Nessus relies on the presence of the package as reported by the vendor.
