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

  - It was found that the Linux kernel's implementation of     vectored pipe read and write functionality did not take     into account the I/O vectors that were already     processed when retrying after a failed atomic access     operation, potentially resulting in memory corruption     due to an I/O vector array overrun. A local,     unprivileged user could use this flaw to crash the     system or, potentially, escalate their privileges on     the system.(CVE-2015-1805)

  - net/llc/sysctl_net_llc.c in the Linux kernel before     3.19 uses an incorrect data type in a sysctl table,     which allows local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry.(CVE-2015-2041)

  - net/rds/sysctl.c in the Linux kernel before 3.19 uses     an incorrect data type in a sysctl table, which allows     local users to obtain potentially sensitive information     from kernel memory or possibly have unspecified other     impact by accessing a sysctl entry.(CVE-2015-2042)

  - Xen 3.3.x through 4.5.x and the Linux kernel through     3.19.1 do not properly restrict access to PCI command     registers, which might allow local guest OS users to     cause a denial of service (non-maskable interrupt and     host crash) by disabling the (1) memory or (2) I/O     decoding for a PCI Express device and then accessing     the device, which triggers an Unsupported Request (UR)     response.(CVE-2015-2150)

  - A stack-based buffer overflow flaw was found in the     Linux kernel's early load microcode functionality. On a     system with UEFI Secure Boot enabled, a local,     privileged user could use this flaw to increase their     privileges to the kernel (ring0) level, bypassing     intended restrictions in place.(CVE-2015-2666)

  - The xsave/xrstor implementation in     arch/x86/include/asm/xsave.h in the Linux kernel before     3.19.2 creates certain .altinstr_replacement pointers     and consequently does not provide any protection     against instruction faulting, which allows local users     to cause a denial of service (panic) by triggering a     fault, as demonstrated by an unaligned memory operand     or a non-canonical address memory     operand.(CVE-2015-2672)

  - A flaw was found in the way the Linux kernel's 32-bit     emulation implementation handled forking or closing of     a task with an 'int80' entry. A local user could     potentially use this flaw to escalate their privileges     on the system.(CVE-2015-2830)

  - It was found that the Linux kernel's TCP/IP protocol     suite implementation for IPv6 allowed the Hop Limit     value to be set to a smaller value than the default     one. An attacker on a local network could use this flaw     to prevent systems on that network from sending or     receiving network packets.(CVE-2015-2922)

  - A flaw was found in the way the Linux kernel's file     system implementation handled rename operations in     which the source was inside and the destination was     outside of a bind mount. A privileged user inside a     container could use this flaw to escape the bind mount     and, potentially, escalate their privileges on the     system.(CVE-2015-2925)

  - A race condition flaw was found in the way the Linux     kernel's SCTP implementation handled Address     Configuration lists when performing Address     Configuration Change (ASCONF). A local attacker could     use this flaw to crash the system via a race condition     triggered by setting certain ASCONF options on a     socket.(CVE-2015-3212)

  - 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)

  - A flaw was found in the way the Linux kernel's nested     NMI handler and espfix64 functionalities interacted     during NMI processing. A local, unprivileged user could     use this flaw to crash the system or, potentially,     escalate their privileges on the system.(CVE-2015-3290)

  - It was found that if a Non-Maskable Interrupt (NMI)     occurred immediately after a SYSCALL call or before a     SYSRET call with the user RSP pointing to the NMI IST     stack, the kernel could skip that NMI.(CVE-2015-3291)

  - A buffer overflow flaw was found in the way the Linux     kernel's Intel AES-NI instructions optimized version of     the RFC4106 GCM mode decryption functionality handled     fragmented packets. A remote attacker could use this     flaw to crash, or potentially escalate their privileges     on, a system over a connection with an active AES-GCM     mode IPSec security association.(CVE-2015-3331)

  - A race condition flaw was found between the chown and     execve system calls. When changing the owner of a     setuid user binary to root, the race condition could     momentarily make the binary setuid root. A local,     unprivileged user could potentially use this flaw to     escalate their privileges on the system.(CVE-2015-3339)

  - It was found that the Linux kernel's ping socket     implementation did not properly handle socket unhashing     during spurious disconnects, which could lead to a     use-after-free flaw. On x86-64 architecture systems, a     local user able to create ping sockets could use this     flaw to crash the system. On non-x86-64 architecture     systems, a local user able to create ping sockets could     use this flaw to escalate their privileges on the     system.(CVE-2015-3636)

  - An inode data validation error was found in Linux     kernels built with UDF file system (CONFIG_UDF_FS)     support. An attacker able to mount a     corrupted/malicious UDF file system image could cause     the kernel to crash.(CVE-2015-4167)

  - A flaw was discovered in the way the Linux kernel's TTY     subsystem handled the tty shutdown phase. A local,     unprivileged user could use this flaw to cause denial     of service on the system by holding a reference to the     ldisc lock during tty shutdown, causing a     deadlock.(CVE-2015-4170)

  - A flaw was discovered in the kernel's collect_mounts     function. If the kernel's audit subsystem called     collect_mounts to audit an unmounted path, it could     panic the system. With this flaw, an unprivileged user     could call umount(MNT_DETACH) to launch a     denial-of-service attack.(CVE-2015-4177)

  - A DoS flaw was found for a Linux kernel built for the     x86 architecture which had the KVM virtualization     support(CONFIG_KVM) enabled. The kernel would be     vulnerable to a NULL pointer dereference flaw in Linux     kernel's kvm_apic_has_events() function while doing an     ioctl. An unprivileged user able to access the     '/dev/kvm' device could use this flaw to crash the     system kernel.(CVE-2015-4692)

  - A flaw was found in the kernel's implementation of the     Berkeley Packet Filter (BPF). A local attacker could     craft BPF code to crash the system by creating a     situation in which the JIT compiler would fail to     correctly optimize the JIT image on the last pass. This     would lead to the CPU executing instructions that were     not part of the JIT code.(CVE-2015-4700)

  - A buffer overflow flaw was found in the way the Linux     kernel's virtio-net subsystem handled certain fraglists     when the GRO (Generic Receive Offload) functionality     was enabled in a bridged network configuration. An     attacker on the local network could potentially use     this flaw to crash the system, or, although unlikely,     elevate their privileges on the system.(CVE-2015-5156)

  - An issue was discovered in the hwpoison implementation     in mm/memory-failure.c in the Linux kernel before     5.0.4. When soft_offline_in_use_page() runs on a thp     tail page after pmd is split, an attacker can cause a     denial of service (BUG).(CVE-2019-10124i1/4%0

  - A stack-based buffer overflow flaw was found in the     Linux kernel's early load microcode functionality. On a     system with UEFI Secure Boot enabled, a local,     privileged user could use this flaw to increase their     privileges to the kernel (ring0) level, bypassing     intended restrictions in place.(CVE-2015-2666i1/4%0

  - A flaw was found in the way the Linux kernel's     networking subsystem handled offloaded packets with     multiple layers of encapsulation in the GRO (Generic     Receive Offload) code path. A remote attacker could use     this flaw to trigger unbounded recursion in the kernel     that could lead to stack corruption, resulting in a     system crash.(CVE-2016-8666i1/4%0

  - The ethtool_get_wol function in net/core/ethtool.c in     the Linux kernel through 4.7, as used in Android before     2016-08-05 on Nexus 5 and 7 (2013) devices, does not     initialize a certain data structure, which allows local     users to obtain sensitive information via a crafted     application, aka Android internal bug 28803952 and     Qualcomm internal bug CR570754.(CVE-2014-9900i1/4%0

  - A vulnerability was found in crypto/ahash.c in the     Linux kernel which allows attackers to cause a denial     of service (API operation calling its own callback, and     infinite recursion) by triggering EBUSY on a full     queue.(CVE-2017-7618i1/4%0

  - drivers/misc/qseecom.c in the QSEECOM driver for the     Linux kernel 3.x, as used in Qualcomm Innovation Center     (QuIC) Android contributions for MSM devices and other     products, does not validate certain offset, length, and     base values within an ioctl call, which allows     attackers to gain privileges or cause a denial of     service (memory corruption) via a crafted     application.(CVE-2014-4322i1/4%0

  - An integer overflow vulnerability was found in the     Linux kernel in xt_alloc_table_info, which on 32-bit     systems can lead to small structure allocation and a     copy_from_user based heap corruption.(CVE-2016-3135i1/4%0

  - The l2tp_ip_recvmsg function in net/l2tp/l2tp_ip.c in     the Linux kernel before 3.12.4 updates a certain length     value before ensuring that an associated data structure     has 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.(CVE-2013-7264i1/4%0

  - A bypass was found for the Spectre v1 hardening in the     eBPF engine of the Linux kernel. The code in the     kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic in     various cases, including cases of different branches     with different state or limits to sanitize, leading to     side-channel attacks.(CVE-2019-7308i1/4%0

  - The tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c 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-2017-9077i1/4%0

  - The cgroup offline implementation in the Linux kernel     through 4.8.11 mishandles certain drain operations,     which allows local users to cause a denial of service     (system hang) by leveraging access to a container     environment for executing a crafted application, as     demonstrated by trinity.(CVE-2016-9191i1/4%0

  - The KVM implementation in the Linux kernel through     4.20.5 has a Use-after-Free.(CVE-2019-7221i1/4%0

  - The drivers/media/usb/dvb-usb-v2/lmedm04.c in the Linux     kernel, through 4.13.11, allows local users to cause a     denial of service (general protection fault and system     crash) or possibly have unspecified other impact via a     crafted USB device, related to a missing warm-start     check and incorrect attach timing     (dm04_lme2510_frontend_attach versus     dm04_lme2510_tuner).(CVE-2017-16538i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's Advanced Linux Sound Architecture (ALSA)     implementation handled user controls. A local,     privileged user could use this flaw to crash the     system.(CVE-2014-4653i1/4%0

  - A vulnerability leading to a local privilege escalation     was found in apparmor in the Linux kernel. When     proc_pid_attr_write() was changed to use memdup_user     apparmor's (interface violating) assumption that the     setprocattr buffer was always a single page was     violated.(CVE-2016-6187i1/4%0

  - A vulnerability was found in the Linux kernel in     'tmpfs' file system. When file permissions are modified     via 'chmod' and the user is not in the owning group or     capable of CAP_FSETID, the setgid bit is cleared in     inode_change_ok(). Setting a POSIX ACL via 'setxattr'     sets the file permissions as well as the new ACL, but     doesn't clear the setgid bit in a similar way this     allows to bypass the check in 'chmod'.(CVE-2017-5551i1/4%0

  - A flaw was found in the Linux Kernel in the     ucma_leave_multicast() function in     drivers/infiniband/core/ucma.c which allows access to a     certain data structure after freeing it in     ucma_process_join(). This allows an attacker to cause a     use-after-free bug and to induce kernel memory     corruption, leading to a system crash or other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2018-14734i1/4%0

  - CVE-2014-9428: The batadv_frag_merge_packets function in     net/batman-adv/fragmentation.c in the B.A.T.M.A.N.
    implementation in the Linux kernel used an incorrect     length field during a calculation of an amount of     memory, which allowed remote attackers to cause a denial     of service (mesh-node system crash) via fragmented     packets.

  - CVE-2014-8160:
    net/netfilter/nf_conntrack_proto_generic.c in the Linux     kernel generated incorrect conntrack entries during     handling of certain iptables rule sets for the SCTP,     DCCP, GRE, and UDP-Lite protocols, which allowed remote     attackers to bypass intended access restrictions via     packets with disallowed port numbers.

  - CVE-2014-9529: Race condition in the key_gc_unused_keys     function in security/keys/gc.c in the Linux kernel     allowed 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-2014-9420: The rock_continue function in     fs/isofs/rock.c in the Linux kernel did not restrict the     number of Rock Ridge continuation entries, which allowed     local users to cause a denial of service (infinite loop,     and system crash or hang) via a crafted iso9660 image.

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

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

  - CVE-2014-8559: The d_walk function in fs/dcache.c in the     Linux kernel through did not properly maintain the     semantics of rename_lock, which allowed local users to     cause a denial of service (deadlock and system hang) via     a crafted application.

  - CVE-2014-8134: The paravirt_ops_setup function in     arch/x86/kernel/kvm.c in the Linux kernel used an     improper paravirt_enabled setting for KVM guest kernels,     which made it easier for guest OS users to bypass the     ASLR protection mechanism via a crafted application that     reads a 16-bit value.

Following security bugs were fixed :

  - CVE-2016-0728: A reference leak in keyring handling with     join_session_keyring() could lead to local attackers     gain root privileges. (bsc#962075).

  - CVE-2015-7550: A local user could have triggered a race     between read and revoke in keyctl (bnc#958951).

  - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect     functions in drivers/net/ppp/pptp.c in the Linux kernel     did not verify an address length, which allowed local     users to obtain sensitive information from kernel memory     and bypass the KASLR protection mechanism via a crafted     application (bnc#959190).

  - CVE-2015-8543: The networking implementation in the     Linux kernel did not validate protocol identifiers for     certain protocol families, which allowed local users to     cause a denial of service (NULL function pointer     dereference and system crash) or possibly gain     privileges by leveraging CLONE_NEWUSER support to     execute a crafted SOCK_RAW application (bnc#958886).

  - CVE-2014-8989: The Linux kernel did not properly     restrict dropping of supplemental group memberships in     certain namespace scenarios, which allowed local users     to bypass intended file permissions by leveraging a     POSIX ACL containing an entry for the group category     that is more restrictive than the entry for the other     category, aka a 'negative groups' issue, related to     kernel/groups.c, kernel/uid16.c, and     kernel/user_namespace.c (bnc#906545).

  - CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux     kernel on the x86_64 platform mishandles IRET faults in     processing NMIs that occurred during userspace     execution, which might allow local users to gain     privileges by triggering an NMI (bnc#937969).

  - CVE-2015-7799: The slhc_init function in     drivers/net/slip/slhc.c in the Linux kernel through     4.2.3 did not ensure that certain slot numbers are     valid, which allowed local users to cause a denial of     service (NULL pointer dereference and system crash) via     a crafted PPPIOCSMAXCID ioctl call (bnc#949936).

  - CVE-2015-8104: The KVM subsystem in the Linux kernel     through 4.2.6, and Xen 4.3.x through 4.6.x, allowed     guest OS users to cause a denial of service (host OS     panic or hang) by triggering many #DB (aka Debug)     exceptions, related to svm.c (bnc#954404).

  - CVE-2015-5307: The KVM subsystem in the Linux kernel     through 4.2.6, and Xen 4.3.x through 4.6.x, allowed     guest OS users to cause a denial of service (host OS     panic or hang) by triggering many #AC (aka Alignment     Check) exceptions, related to svm.c and vmx.c     (bnc#953527).

  - CVE-2014-9529: Race condition in the key_gc_unused_keys     function in security/keys/gc.c in the Linux kernel     allowed 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     (bnc#912202).

  - CVE-2015-7990: Race condition in the rds_sendmsg     function in net/rds/sendmsg.c in the Linux kernel     allowed local users to cause a denial of service (NULL     pointer dereference and system crash) or possibly have     unspecified other impact by using a socket that was not     properly bound. NOTE: this vulnerability exists because     of an incomplete fix for CVE-2015-6937 (bnc#952384     953052).

  - CVE-2015-6937: The __rds_conn_create function in     net/rds/connection.c in the Linux kernel allowed local     users to cause a denial of service (NULL pointer     dereference and system crash) or possibly have     unspecified other impact by using a socket that was not     properly bound (bnc#945825).

  - CVE-2015-7885: The dgnc_mgmt_ioctl function in     drivers/staging/dgnc/dgnc_mgmt.c in the Linux kernel     through 4.3.3 did not initialize a certain structure     member, which allowed local users to obtain sensitive     information from kernel memory via a crafted application     (bnc#951627).

  - CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in     the Linux kernel did not validate attempted changes to     the MTU value, which allowed context-dependent attackers     to cause a denial of service (packet loss) via a value     that is (1) smaller than the minimum compliant value or     (2) larger than the MTU of an interface, as demonstrated     by a Router Advertisement (RA) message that is not     validated by a daemon, a different vulnerability than     CVE-2015-0272. NOTE: the scope of CVE-2015-0272 is     limited to the NetworkManager product (bnc#955354).

  - CVE-2015-8767: A case can occur when sctp_accept() is     called by the user during a heartbeat timeout event     after the 4-way handshake. Since sctp_assoc_migrate()     changes both assoc->base.sk and assoc->ep, the     bh_sock_lock in sctp_generate_heartbeat_event() will be     taken with the listening socket but released with the     new association socket. The result is a deadlock on any     future attempts to take the listening socket lock.
    (bsc#961509)

  - CVE-2015-8575: Validate socket address length in     sco_sock_bind() to prevent information leak     (bsc#959399).

  - CVE-2015-8551, CVE-2015-8552: xen/pciback: For     XEN_PCI_OP_disable_msi[|x] only disable if device has     MSI(X) enabled (bsc#957990).

  - CVE-2015-8550: Compiler optimizations in the XEN PV     backend drivers could have lead to double fetch     vulnerabilities, causing denial of service or arbitrary     code execution (depending on the configuration)     (bsc#957988).

The following non-security bugs were fixed :

  - ALSA: hda - Disable 64bit address for Creative HDA     controllers (bnc#814440).
