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

  - An issue was discovered in the Linux kernel before     4.18.7. In block/blk-core.c, there is an
    __blk_drain_queue() use-after-free because a certain     error case is mishandled.(CVE-2018-20856)

  - In the Linux kernel before 5.1.7, a device can be     tracked by an attacker using the IP ID values the     kernel produces for connection-less protocols (e.g.,     UDP and ICMP). When such traffic is sent to multiple     destination IP addresses, it is possible to obtain hash     collisions (of indices to the counter array) and     thereby obtain the hashing key (via enumeration). An     attack may be conducted by hosting a crafted web page     that uses WebRTC or gQUIC to force UDP traffic to     attacker-controlled IP addresses.(CVE-2019-10638)

  - The Linux kernel 4.x (starting from 4.1) and 5.x before     5.0.8 allows Information Exposure (partial kernel     address disclosure), leading to a KASLR bypass.
    Specifically, it is possible to extract the KASLR     kernel image offset using the IP ID values the kernel     produces for connection-less protocols (e.g., UDP and     ICMP). When such traffic is sent to multiple     destination IP addresses, it is possible to obtain hash     collisions (of indices to the counter array) and     thereby obtain the hashing key (via enumeration). This     key contains enough bits from a kernel address (of a     static variable) so when the key is extracted (via     enumeration), the offset of the kernel image is     exposed. This attack can be carried out remotely, by     the attacker forcing the target device to send UDP or     ICMP (or certain other) traffic to attacker-controlled     IP addresses. Forcing a server to send UDP traffic is     trivial if the server is a DNS server. ICMP traffic is     trivial if the server answers ICMP Echo requests     (ping). For client targets, if the target visits the     attacker's web page, then WebRTC or gQUIC can be used     to force UDP traffic to attacker-controlled IP     addresses.(CVE-2019-10639)

  - The Linux kernel was found vulnerable to an integer     overflow in the     drivers/video/fbdev/uvesafb.c:uvesafb_setcmap()     function. The vulnerability could result in local     attackers being able to crash the kernel or potentially     elevate privileges.(CVE-2018-13406)

  - The SCTP socket buffer used by a userspace application     is not accounted by the cgroups subsystem. An attacker     can use this flaw to cause a denial of service     attack.(CVE-2019-3874)

  - The Linux kernel before 5.1-rc5 allows     page-i1/4z_refcount reference count overflow, with     resultant use-after-free issues, if about 140 GiB of     RAM exists. This is related to fs/fuse/dev.c,     fs/pipe.c, fs/splice.c, include/linux/mm.h,     include/linux/pipe_fs_i.h, kernel/trace/trace.c,     mm/gup.c, and mm/hugetlb.c. It can occur with FUSE     requests.(CVE-2019-11487)

  - A flaw was found in the Linux kernel's implementation     of ext4 extent management. The kernel doesn't correctly     initialize memory regions in the extent tree block     which may be exported to a local user to obtain     sensitive information by reading empty/uninitialized     data from the filesystem.(CVE-2019-11833)

  - A flaw was found in the Linux kernel's implementation     of the Bluetooth Human Interface Device Protocol     (HIDP). A local attacker with access permissions to the     Bluetooth device can issue an IOCTL which will trigger     the do_hidp_sock_ioctl function in     net/bluetooth/hidp/sock.c.c. This function can leak     potentially sensitive information from the kernel stack     memory via a HIDPCONNADD command because a name field     may not be correctly NULL terminated.(CVE-2019-11884)

  - The Linux kernel is vulnerable to an out-of-bounds read     in ext4/balloc.c:ext4_valid_block_bitmap() function. An     attacker could trick a legitimate user or a privileged     attacker could exploit this by mounting a crafted ext4     image to cause a crash.(CVE-2018-1093)
