Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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 :

  - In f2fs_xattr_generic_list of xattr.c, there is a     possible out of bounds read due to a missing bounds     check. This could lead to local information disclosure     with System execution privileges needed. User     interaction is not required for     exploitation.(CVE-2020-0067)

  - An issue was discovered in the Linux kernel before 5.2     on the powerpc platform.
    arch/powerpc/kernel/idle_book3s.S does not have     save/restore functionality for PNV_POWERSAVE_AMR,     PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR, aka     CID-53a712bae5dd.(CVE-2020-11669)

  - 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)

  - 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)

  - 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)

  - 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)

  - A flaw was found in the Linux kernel's implementation     of some networking protocols in IPsec, such as VXLAN     and GENEVE tunnels over IPv6. When an encrypted tunnel     is created between two hosts, the kernel isn't     correctly routing tunneled data over the encrypted link     rather sending the data unencrypted. This would allow     anyone in between the two endpoints to read the traffic     unencrypted. The main threat from this vulnerability is     to data confidentiality.(CVE-2020-1749)

  - 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.(CVE-2020-11565)

  - An issue was discovered in slc_bump in     drivers/net/can/slcan.c in the Linux kernel through     5.6.2. It allows attackers to read uninitialized     can_frame data, potentially containing sensitive     information from kernel stack memory, if the     configuration lacks CONFIG_INIT_STACK_ALL, aka     CID-b9258a2cece4.(CVE-2020-11494)

  - btrfs_root_node in fs/btrfs/ctree.c in the Linux kernel     through 5.3.12 allows a NULL pointer dereference     because rcu_dereference(root->node) can be     zero.(CVE-2019-19036)

  - ext4_empty_dir in fs/ext4/namei.c in the Linux kernel     through 5.3.12 allows a NULL pointer dereference     because ext4_read_dirblock(inode,0,DIRENT_HTREE) can be     zero.(CVE-2019-19037)

  - __btrfs_free_extent in fs/btrfs/extent-tree.c in the     Linux kernel through 5.3.12 calls btrfs_print_leaf in a     certain ENOENT case, which allows local users to obtain     potentially sensitive information about register values     via the dmesg program.(CVE-2019-19039)

  - In the Linux kernel 5.0.21, mounting a crafted f2fs     filesystem image can cause a NULL pointer dereference     in f2fs_recover_fsync_data in fs/f2fs/recovery.c. This     is related to F2FS_P_SB in     fs/f2fs/f2fs.h.(CVE-2019-19815)

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.

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

  - 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)

  - The fix for CVE-2019-11599, affecting the Linux kernel     before 5.0.10 was not complete. A local user could use     this flaw to obtain sensitive information, cause a     denial of service, or possibly have other unspecified     impacts by triggering a race condition with     mmget_not_zero or get_task_mm calls.(CVE-2019-14898)

  - A pivot_root race condition in fs/namespace.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)

  - 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)

  - 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)

  - 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 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)

  - In nfc_llcp_build_sdreq_tlv of llcp_commands.c, there     is a possible out of bounds write due to a missing     bounds check. This could lead to local escalation of     privilege with System execution privileges needed. User     interaction is not needed for exploitation. Product:
    Android. Versions: Android kernel. Android ID:
    A-73083945.(CVE-2018-9518)

  - An issue was discovered in slc_bump in     drivers/net/can/slcan.c in the Linux kernel through     5.6.2. It allows attackers to read uninitialized     can_frame data, potentially containing sensitive     information from kernel stack memory, if the     configuration lacks CONFIG_INIT_STACK_ALL, aka     CID-b9258a2cece4.(CVE-2020-11494)

  - In the Android kernel in sync debug fs driver there is     a kernel pointer leak due to the usage of printf with     %p. This could lead to local information disclosure     with system execution privileges needed. User     interaction is not needed for     exploitation.(CVE-2019-9444)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - drivers/gpu/drm/radeon/radeon_display.c in the Linux     kernel 5.2.14 does not check the alloc_workqueue return     value, leading to a NULL pointer dereference. NOTE: A     third-party software maintainer states that the work     queue allocation is happening during device     initialization, which for a graphics card occurs during     boot. It is not attacker controllable and OOM at that     time is highly unlikely.(CVE-2019-16230)

  - In the netlink driver, there is a possible out of     bounds write due to a race condition. 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-65025077(CVE-2020-0066)

  - The kernel in Red Hat Enterprise Linux 7 and MRG-2 does     not clear garbage data for SG_IO buffer, which may     leaking sensitive information to     userspace.(CVE-2014-8181)

  - btrfs_root_node in fs/btrfs/ctree.c in the Linux kernel     through 5.3.12 allows a NULL pointer dereference     because rcu_dereference(root->node) can be     zero.(CVE-2019-19036)
