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 IPv6 DCCP implementation in the Linux kernel     mishandles inheritance, which allows local users to     cause a denial of service or possibly have unspecified     other impact via crafted system calls, a related issue     to CVE-2017-8890. An unprivileged local user could use     this flaw to induce kernel memory corruption on the     system, leading to a crash. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-9076i1/4%0

  - It was found that the driver_override implementation in     base/platform.c in the Linux kernel is susceptible to     race condition when different threads are reading vs     storing a different driver override.(CVE-2017-12146i1/4%0

  - The Linux Kernel imposes a size restriction on the     arguments and environmental strings passed through     RLIMIT_STACK/RLIMIT_INFINITY, but does not take the     argument and environment pointers into account, which     allows attackers to bypass this     limitation.(CVE-2017-1000365i1/4%0

  - A buffer overflow flaw was found in the way the Linux     kernel's eCryptfs implementation decoded encrypted file     names. A local, unprivileged user could use this flaw     to crash the system or, potentially, escalate their     privileges on the system.(CVE-2014-9683i1/4%0

  - 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-2018-13406i1/4%0

  - A NULL pointer dereference flaw was found in the way     the Linux kernel's Common Internet File System (CIFS)     implementation handled mounting of file system shares.
    A remote attacker could use this flaw to crash a client     system that would mount a file system share from a     malicious server.(CVE-2014-7145i1/4%0

  - The udp6_ufo_fragment function in     net/ipv6/udp_offload.c in the Linux kernel through     3.12, when UDP Fragmentation Offload (UFO) is enabled,     does not properly perform a certain size comparison     before inserting a fragment header, which allows remote     attackers to cause a denial of service (panic) via a     large IPv6 UDP packet, as demonstrated by use of the     Token Bucket Filter (TBF) queueing     discipline.(CVE-2013-4563i1/4%0

  - The do_umount function in fs/namespace.c in the Linux     kernel through 3.17 does not require the CAP_SYS_ADMIN     capability for do_remount_sb calls that change the root     filesystem to read-only, which allows local users to     cause a denial of service (loss of writability) by     making certain unshare system calls, clearing the /     MNT_LOCKED flag, and making an MNT_FORCE umount system     call.(CVE-2014-7975i1/4%0

  - drivers/tty/n_tty.c in the Linux kernel before 4.14.11     allows local attackers (who are able to access pseudo     terminals) to hang/block further usage of any pseudo     terminal devices due to an EXTPROC versus ICANON     confusion in TIOCINQ.(CVE-2018-18386i1/4%0

Multiple vulnerabilities has been found and corrected in the Linux kernel :

The SCTP implementation in the Linux kernel before 3.17.4 allows remote attackers to cause a denial of service (memory consumption) by triggering a large number of chunks in an association's output queue, as demonstrated by ASCONF probes, related to net/sctp/inqueue.c and net/sctp/sm_statefuns.c (CVE-2014-3688=.

Buffer overflow in net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, allows remote attackers to cause a denial of service (memory corruption and panic) or possibly have unspecified other impact via a long unencrypted auth ticket (CVE-2014-6416).

net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly consider the possibility of kmalloc failure, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a long unencrypted auth ticket (CVE-2014-6417).

net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly validate auth replies, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via crafted data from the IP address of a Ceph Monitor (CVE-2014-6418).

The sctp_process_param function in net/sctp/sm_make_chunk.c in the SCTP implementation in the Linux kernel before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via a malformed INIT chunk (CVE-2014-7841).

Race condition in arch/x86/kvm/x86.c in the Linux kernel before 3.17.4 allows guest OS users to cause a denial of service (guest OS crash) via a crafted application that performs an MMIO transaction or a PIO transaction to trigger a guest userspace emulation error report, a similar issue to CVE-2010-5313 (CVE-2014-7842).

arch/x86/kernel/tls.c in the Thread Local Storage (TLS) implementation in the Linux kernel through 3.18.1 allows local users to bypass the espfix protection mechanism, and consequently makes it easier for local users to bypass the ASLR protection mechanism, via a crafted application that makes a set_thread_area system call and later reads a 16-bit value (CVE-2014-8133).

Stack-based buffer overflow in the ttusbdecfe_dvbs_diseqc_send_master_cmd function in drivers/media/usb/ttusb-dec/ttusbdecfe.c in the Linux kernel before 3.17.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via a large message length in an ioctl call (CVE-2014-8884).

The do_double_fault function in arch/x86/kernel/traps.c in the Linux kernel through 3.17.4 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to cause a denial of service (panic) via a modify_ldt system call, as demonstrated by sigreturn_32 in the linux-clock-tests test suite (CVE-2014-9090).

arch/x86/kernel/entry_64.S in the Linux kernel before 3.17.5 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to gain privileges by triggering an IRET instruction that leads to access to a GS Base address from the wrong space (CVE-2014-9322).

The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel through 3.18.1 does not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address (CVE-2014-9419).

The rock_continue function in fs/isofs/rock.c in the Linux kernel through 3.18.1 does not restrict the number of Rock Ridge continuation entries, which allows local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image (CVE-2014-9420).

Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key (CVE-2014-9529).

The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel before 3.18.2 does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted iso9660 image (CVE-2014-9584).

The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD (CVE-2014-9585).

The updated packages provides a solution for these security issues.
