The remote host is missing an update for the Huawei EulerOS 'kernel' package(s) announced via the EulerOS-SA-2019-1505 advisory.
Vulnerability Insight:
A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system.(CVE-2018-5391)
Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer.(CVE-2014-3184)
The __get_data_block function in fs/f2fs/data.c in the Linux kernel before 4.11 allows local users to cause a denial of service (integer overflow and loop) via crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP ioctl.(CVE-2017-18257)
net
etfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations. This allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all network namespaces.(CVE-2017-17450)
A denial of service flaw was discovered in the Linux kernel, where a race condition caused a NULL pointer dereference in the RDS socket-creation code. A local attacker could use this flaw to create a situation in which a NULL pointer crashed the kernel.(CVE-2015-7990)
An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.(CVE-2018-20169)
mm/memory.c in the Linux kernel before 4.1.4 mishandles anonymous pages, which allows local users to gain privileges or cause a denial of service (page tainting) via a crafted application that triggers writing to page zero.(CVE-2015-3288)
The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application.(CVE-2015-8660)
A flaw was found in the Linux kernel where a local user with a shell account can abuse the userfaultfd syscall when using hugetlbfs. A missing size check in hugetlb_mcopy_atomic_pte could create an invalid inode variable, leading to a kernel panic.(CVE-2017-15128)
An integer overflow flaw was found in the way the lzo1x_decompress_safe() function of the Linux kernel's LZO implementation processed Literal Runs. A local attacker could, in extremely rare cases, use this flaw to crash the system ... [Please see the references for more information on the vulnerabilities]
