The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14354-1 advisory.

  - ** DISPUTED ** An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a     denial of service or possibly have unspecified other impact by changing the value of ioc_number between     two kernel reads of that value, aka a double fetch vulnerability. NOTE: a third party reports that this     is unexploitable because the doubly fetched value is not used. (CVE-2019-12456)

  - A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in     Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly     execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.
    (CVE-2019-14896)

  - A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip     driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary     code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and     connects to another STA. (CVE-2019-14897)

  - An issue was discovered in the Linux kernel before 5.2.3. There is a use-after-free caused by a malicious     USB device in the drivers/media/usb/dvb-usb/dvb-usb-init.c driver. (CVE-2019-15213)

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 :

  - In the Linux kernel 5.4.0-rc2, there is a     use-after-free (read) in the __blk_add_trace function     in kernel/trace/blktrace.c (which is used to fill out a     blk_io_trace structure and place it in a per-cpu     sub-buffer).(CVE-2019-19768)

  - The Linux kernel through 5.3.13 has a start_offset+size     Integer Overflow in cpia2_remap_buffer in     drivers/media/usb/cpia2/cpia2_core.c because cpia2 has     its own mmap implementation. This allows local users     (with /dev/video0 access) to obtain read and write     permissions on kernel physical pages, which can     possibly result in a privilege     escalation.(CVE-2019-18675)

  - An issue was discovered in the Linux kernel through     5.5.6. set_fdc in drivers/block/floppy.c leads to a     wait_til_ready out-of-bounds read because the FDC index     is not checked for errors before assigning it, aka     CID-2e90ca68b0d2.(CVE-2020-9383)

  - There is a use-after-free vulnerability in the Linux     kernel through 5.5.2 in the vgacon_invert_region     function in     drivers/video/console/vgacon.c.(CVE-2020-8649)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER.
    ConsultIDs: CVE-2020-12826. Reason: This candidate is a     duplicate of CVE-2020-12826. Notes: All CVE users     should reference CVE-2020-12826 instead of this     candidate. All references and descriptions in this     candidate have been removed to prevent accidental     usage.(CVE-2020-10741)

  - 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)

  - gadget_dev_desc_UDC_store in     drivers/usb/gadget/configfs.c in the Linux kernel     through 5.6.13 relies on kstrdup without considering     the possibility of an internal '\0' value, which allows     attackers to trigger an out-of-bounds read, aka     CID-15753588bcd4.(CVE-2020-13143)

  - 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 found in Linux kernel before 5.5.4.
    mwifiex_ret_wmm_get_status() in     drivers/net/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)

  - An issue was found in Linux kernel before 5.5.4. The     mwifiex_cmd_append_vsie_tlv() function in     drivers/net/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)

  - 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)

  - 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)

  - In the Linux kernel before 5.6.1,     drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink     camera USB driver) mishandles invalid descriptors, aka     CID-a246b4d54770.(CVE-2020-11668)

  - An issue was discovered in the stv06xx subsystem in the     Linux kernel before 5.6.1.
    drivers/media/usb/gspca/stv06xx/stv06xx.c and     drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c     mishandle invalid descriptors, as demonstrated by a     NULL pointer dereference, aka     CID-485b06aadb93.(CVE-2020-11609)

  - An issue was discovered in the Linux kernel before     5.6.1. drivers/media/usb/gspca/ov519.c allows NULL     pointer dereferences in ov511_mode_init_regs and     ov518_mode_init_regs when there are zero endpoints, aka     CID-998912346c0d.(CVE-2020-11608)

  - ** DISPUTED ** 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)

  - 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 Linux kernel before 5.5.8, get_raw_socket in     drivers/vhost/net.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.
