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 Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The offset2lib patch as used in the Linux Kernel     contains a vulnerability that allows a PIE binary to be     execve()'ed with 1GB of arguments or environmental     strings then the stack occupies the address 0x80000000     and the PIE binary is mapped above 0x40000000     nullifying the protection of the offset2lib patch. This     affects Linux Kernel version 4.11.5 and earlier. This     is a different issue than CVE-2017-1000371. This issue     appears to be limited to i386 based     systems.(CVE-2017-1000370i1/4%0

  - Integer overflow in the LZ4 algorithm implementation,     as used in Yann Collet LZ4 before r118 and in the     lz4_uncompress function in lib/lz4/lz4_decompress.c in     the Linux kernel before 3.15.2, on 32-bit platforms     might allow context-dependent attackers to cause a     denial of service (memory corruption) or possibly have     unspecified other impact via a crafted Literal Run that     would be improperly handled by programs not complying     with an API limitation, a different vulnerability than     CVE-2014-4715.(CVE-2014-4611i1/4%0

  - The replace_map_fd_with_map_ptr function in     kernel/bpf/verifier.c in the Linux kernel before 4.5.5     does not properly maintain an fd data structure, which     allows local users to gain privileges or cause a denial     of service (use-after-free) via crafted BPF     instructions that reference an incorrect file     descriptor.(CVE-2016-4557i1/4%0

  - The usb_destroy_configuration() function, in     'drivers/usb/core/config.c' in the USB core subsystem,     in the Linux kernel through 4.14.5 does not consider     the maximum number of configurations and interfaces     before attempting to release resources. This allows     local users to cause a denial of service, due to     out-of-bounds write access, or possibly have     unspecified other impact via a crafted USB device. Due     to the nature of the flaw, privilege escalation cannot     be fully ruled out, although we believe it is     unlikely.(CVE-2017-17558i1/4%0

  - The cdrom_ioctl_media_changed function in     drivers/cdrom/cdrom.c in the Linux kernel before 4.16.6     allows local attackers to use a incorrect bounds check     in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read     out kernel memory.(CVE-2018-10940i1/4%0

  - It was found that the parse_rock_ridge_inode_internal()     function of the Linux kernel's ISOFS implementation did     not correctly check relocated directories when     processing Rock Ridge child link (CL) tags. An attacker     with physical access to the system could use a     specially crafted ISO image to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-5471i1/4%0

  - A flaw was found in the Linux kernel's implementation     of Unix sockets. A server polling for client-socket     data could put the peer socket on a wait list the peer     socket could then close the connection, making the     reference on the wait list no longer valid. This could     lead to bypassing the permissions on a Unix socket and     packets being injected into the stream, and could also     panic the machine (denial of service).(CVE-2013-7446i1/4%0

  - The do_check function in kernel/bpf/verifier.c in the     Linux kernel before 4.11.1 does not make the     allow_ptr_leaks value available for restricting the     output of the print_bpf_insn function, which allows     local users to obtain sensitive address information via     crafted bpf system calls.(CVE-2017-9150i1/4%0

  - The WLAN (aka Wi-Fi) driver for the Linux kernel 3.x     and 4.x, as used in Qualcomm Innovation Center (QuIC)     Android contributions for MSM devices and other     products, does not verify authorization for private SET     IOCTL calls, which allows attackers to gain privileges     via a crafted application, related to     wlan_hdd_hostapd.c and     wlan_hdd_wext.c.(CVE-2015-0571i1/4%0

  - arch/arm64/kvm/guest.c in KVM in the Linux kernel     before 4.18.12 on the arm64 platform mishandles the     KVM_SET_ON_REG ioctl. This is exploitable by attackers     who can create virtual machines. An attacker can     arbitrarily redirect the hypervisor flow of control     (with full register control). An attacker can also     cause a denial of service (hypervisor panic) via an     illegal exception return. This occurs because of     insufficient restrictions on userspace access to the     core register file, and because PSTATE.M validation     does not prevent unintended execution     modes.(CVE-2018-18021i1/4%0

  - A resource-exhaustion vulnerability was found in the     kernel, where an unprivileged process could allocate     and accumulate far more file descriptors than the     process' limit. A local, unauthenticated user could     exploit this flaw by sending file descriptors over a     Unix socket and then closing them to keep the process'     fd count low, thereby creating kernel-memory or     file-descriptors exhaustion (denial of     service).(CVE-2016-2550i1/4%0

  - The Linux kernel before 3.12.4 updates certain length     values before ensuring that associated data structures     have been initialized, which allows local users to     obtain sensitive information from kernel stack memory     via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system     call, related to net/ipv4/ping.c, net/ipv4/raw.c,     net/ipv4/udp.c, net/ipv6/raw.c, and     net/ipv6/udp.c.(CVE-2013-7263i1/4%0

  - It is possible for a single process to cause an OOM     condition by filling large pipes with data that are     never read. A typical process filling 4096 pipes with 1     MB of data will use 4 GB of memory and there can be     multiple such processes, up to a     per-user-limit.(CVE-2016-2847i1/4%0

  - The __get_user_asm_ex macro in     arch/x86/include/asm/uaccess.h in the Linux kernel     before 4.7.5 does not initialize a certain integer     variable, which allows local users to obtain sensitive     information from kernel stack memory by triggering     failure of a get_user_ex call.(CVE-2016-9178i1/4%0

  - It was found that the x86 ISA (Instruction Set     Architecture) is prone to a denial of service attack     inside a virtualized environment in the form of an     infinite loop in the microcode due to the way     (sequential) delivering of benign exceptions such as     #DB (debug exception) is handled. A privileged user     inside a guest could use this flaw to create denial of     service conditions on the host kernel.(CVE-2015-8104i1/4%0

  - The Direct Rendering Manager (DRM) subsystem in the     Linux kernel through 4.x mishandles requests for     Graphics Execution Manager (GEM) objects, which allows     context-dependent attackers to cause a denial of     service (memory consumption) via an application that     processes graphics data, as demonstrated by JavaScript     code that creates many CANVAS elements for rendering by     Chrome or Firefox.(CVE-2013-7445i1/4%0

  - A flaw was found in the Linux kernel which does not     initialize certain data structures used by DMA transfer     on ARM64 based systems. This could allow local users to     obtain sensitive information from kernel memory by     triggering a dma_mmap call and reconstructing the     data.(CVE-2015-8950i1/4%0

  - A race condition was found in the Linux kernel before     version 4.11-rc1 in 'fs/timerfd.c' file which allows a     local user to cause a kernel list corruption or     use-after-free via simultaneous operations with a file     descriptor which leverage improper 'might_cancel'     queuing. An unprivileged local user could use this flaw     to cause a denial of service of the system. Due to the     nature of the flaw, privilege escalation cannot be     fully ruled out, although we believe it is     unlikely.(CVE-2017-10661i1/4%0
