According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities :

  - 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.

  - 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.

  - The sctp_v6_create_accept_sk function in     net/sctp/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.

  - The IPv6 fragmentation implementation in the Linux     kernel through 4.11.1 does not consider that the     nexthdr field may be associated with an invalid option,     which allows local users to cause a denial of service     (out-of-bounds read and BUG) or possibly have     unspecified other impact via crafted socket and send     system calls.

  - The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allows attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call. 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.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2017-7487

Li Qiang reported a reference counter leak in the ipxitf_ioctl function which may result into a use-after-free vulnerability, triggerable when a IPX interface is configured.

CVE-2017-7645

Tuomas Haanpaa and Matti Kamunen from Synopsys Ltd discovered that the NFSv2 and NFSv3 server implementations are vulnerable to an out-of-bounds memory access issue while processing arbitrarily long arguments sent by NFSv2/NFSv3 PRC clients, leading to a denial of service.

CVE-2017-7895

Ari Kauppi from Synopsys Ltd discovered that the NFSv2 and NFSv3 server implementations do not properly handle payload bounds checking of WRITE requests. A remote attacker with write access to a NFS mount can take advantage of this flaw to read chunks of arbitrary memory from both kernel-space and user-space.

CVE-2017-8890

It was discovered that the net_csk_clone_lock() function allows a remote attacker to cause a double free leading to a denial of service or potentially have other impact.

CVE-2017-8924

Johan Hovold found that the io_ti USB serial driver could leak sensitive information if a malicious USB device was connected.

CVE-2017-8925

Johan Hovold found a reference counter leak in the omninet USB serial driver, resulting in a use-after-free vulnerability. This can be triggered by a local user permitted to open tty devices.

CVE-2017-9074

Andrey Konovalov reported that the IPv6 fragmentation implementation could read beyond the end of a packet buffer. A local user or guest VM might be able to use this to leak sensitive information or to cause a denial of service (crash).

CVE-2017-9075

Andrey Konovalov reported that the SCTP/IPv6 implementation wrongly initialised address lists on connected sockets, resulting in a use-after-free vulnerability, a similar issue to CVE-2017-8890. This can be triggered by any local user.

CVE-2017-9076 / CVE-2017-9077 Cong Wang found that the TCP/IPv6 and DCCP/IPv6 implementations wrongly initialised address lists on connected sockets, a similar issue to CVE-2017-9075.

CVE-2017-9242

Andrey Konovalov reported a packet buffer overrun in the IPv6 implementation. A local user could use this for denial of service (memory corruption; crash) and possibly for privilege escalation.

CVE-2017-1000364

The Qualys Research Labs discovered that the size of the stack guard page is not sufficiently large. The stack-pointer can jump over the guard-page and moving from the stack into another memory region without accessing the guard-page. In this case no page-fault exception is raised and the stack extends into the other memory region. An attacker can exploit this flaw for privilege escalation.

The default stack gap protection is set to 256 pages and can be configured via the stack_guard_gap kernel parameter on the kernel command line.

Further details can be found at https://www.qualys.com/2017/06/19/stack-clash/stack-clash.tx t

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

  - A vulnerability was found in the Linux kernel where the     keyctl_set_reqkey_keyring() function leaks the thread     keyring. This allows an unprivileged local user to     exhaust kernel memory and thus cause a     DoS.(CVE-2017-7472)

  - A reference counter leak in Linux kernel in     ipxitf_ioctl function was found which results in a use     after free vulnerability that's triggerable from     unprivileged userspace when IPX interface is     configured.(CVE-2017-7487)

  - A vulnerability was found in the Linux kernel where     filesystems mounted with data=ordered mode may allow an     attacker to read stale data from recently allocated     blocks in new files after a system 'reset' by abusing     ext4 mechanics of delayed allocation.(CVE-2017-7495)

  - A race condition was found in the Linux kernel, present     since v3.14-rc1 through v4.12. The race happens between     threads of inotify_handle_event() and vfs_rename()     while running the rename operation against the same     file. As a result of the race the next slab data or the     slab's free list pointer can be corrupted with     attacker-controlled data, which may lead to the     privilege escalation.(CVE-2017-7533)

  - Kernel memory corruption due to a buffer overflow was     found in brcmf_cfg80211_mgmt_tx() function in Linux     kernels from v3.9-rc1 to v4.13-rc1. The vulnerability     can be triggered by sending a crafted NL80211_CMD_FRAME     packet via netlink. This flaw is unlikely to be     triggered remotely as certain userspace code is needed     for this. 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 it is unlikely.(CVE-2017-7541)

  - An integer overflow vulnerability in     ip6_find_1stfragopt() function was found. A local     attacker that has privileges (of CAP_NET_RAW) to open     raw socket can cause an infinite loop inside the     ip6_find_1stfragopt() function.(CVE-2017-7542)

  - Incorrect error handling in the set_mempolicy() and     mbind() compat syscalls in 'mm/mempolicy.c' in the     Linux kernel allows local users to obtain sensitive     information from uninitialized stack data by triggering     failure of a certain bitmap operation.(CVE-2017-7616)

  - The NFS2/3 RPC client could send long arguments to the     NFS server. These encoded arguments are stored in an     array of memory pages, and accessed using pointer     variables. Arbitrarily long arguments could make these     pointers point outside the array and cause an     out-of-bounds memory access. A remote user or program     could use this flaw to crash the kernel, resulting in     denial of service.(CVE-2017-7645)

  - The NFSv2 and NFSv3 server implementations in the Linux     kernel through 4.10.13 lacked certain checks for the     end of a buffer. A remote attacker could trigger a     pointer-arithmetic error or possibly cause other     unspecified impacts using crafted requests related to     fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.(CVE-2017-7895)

  - It was found that the NFSv4 server in the Linux kernel     did not properly validate layout type when processing     NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A     remote attacker could use this flaw to soft-lockup the     system and thus cause denial of service.(CVE-2017-8797)

  - A use-after-free vulnerability was found in DCCP socket     code affecting the Linux kernel since 2.6.16. This     vulnerability could allow an attacker to their escalate     privileges.(CVE-2017-8824)

  - The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allows attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call. 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-2017-8890)

  - The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel allows     local users to obtain sensitive information (in the     dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an     io_ti USB serial device) to trigger an integer     underflow.(CVE-2017-8924)

  - The IPv6 fragmentation implementation in the Linux     kernel does not consider that the nexthdr field may be     associated with an invalid option, which allows local     users to cause a denial of service (out-of-bounds read     and BUG) or possibly have unspecified other impact via     crafted socket and send system calls. Due to the nature     of the flaw, privilege escalation cannot be fully ruled     out, although we believe it is unlikely.(CVE-2017-9074)

  - The sctp_v6_create_accept_sk function in     net/sctp/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-2017-9075)

  - 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-2017-9076)

  - 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-2017-9077)

  - The __ip6_append_data function in net/ipv6/ip6_output.c     in the Linux kernel through 4.11.3 is too late in     checking whether an overwrite of an skb data structure     may occur, which allows local users to cause a denial     of service (system crash) via crafted system     calls.(CVE-2017-9242)

  - The vmw_gb_surface_define_ioctl function (accessible     via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel through 4.11.4 defines a backup_handle variable     but does not give it an initial value. If one attempts     to create a GB surface, with a previously allocated DMA     buffer to be used as a backup buffer, the backup_handle     variable does not get written to and is then later     returned to user space, allowing local users to obtain     sensitive information from uninitialized kernel memory     via a crafted ioctl call.(CVE-2017-9605)

  - In the Linux kernel versions 4.12, 3.10, 2.6, and     possibly earlier, a race condition vulnerability exists     in the sound system allowing for a potential deadlock     and memory corruption due to use-after-free condition     and thus denial of service. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2018-1000004)

  - The code in the drivers/scsi/libsas/sas_scsi_host.c     file in the Linux kernel allow a physically proximate     attacker to cause a memory leak in the ATA command     queue and, thus, denial of service by triggering     certain failure conditions.(CVE-2018-10021)

  - The kernel_wait4 function in kernel/exit.c in the Linux     kernel, when an unspecified architecture and compiler     is used, might allow local users to cause a denial of     service by triggering an attempted use of the -INT_MIN     value.(CVE-2018-10087)

Security Fix(es) :

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of Load &amp; Store instructions (a commonly     used performance optimization). It relies on the     presence of a precisely-defined instruction sequence in     the privileged code as well as the fact that memory read     from address to which a recent memory write has occurred     may see an older value and subsequently cause an update     into the microprocessor's data cache even for     speculatively executed instructions that never actually     commit (retire). As a result, an unprivileged attacker     could use this flaw to read privileged memory by     conducting targeted cache side-channel attacks.
