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 installation on the remote host is affected by the following vulnerabilities :

  - A vulnerability was found in Linux kernel. There is an     information leak in file 'sound/core/timer.c' of the     latest mainline Linux kernel, the stack object     aEURoetreadaEUR has a total size of 32 bytes. It contains a     8-bytes padding, which is not initialized but sent to     user via copy_to_user(), resulting a kernel     leak.(CVE-2016-4569)

  - A vulnerability was found in Linux kernel. There is an     information leak in file sound/core/timer.c of the     latest mainline Linux kernel. The stack object aEURoer1aEUR     has a total size of 32 bytes. Its field aEURoeeventaEUR and     aEURoevalaEUR both contain 4 bytes padding. These 8 bytes     padding bytes are sent to user without being     initialized.(CVE-2016-4578)

  - The x25_negotiate_facilities function in     net/x25/x25_facilities.c in the Linux kernel before     4.5.5 does not properly initialize a certain data     structure, which allows attackers to obtain sensitive     information from kernel stack memory via an X.25 Call     Request.(CVE-2016-4580)

  - fs/pnode.c in the Linux kernel before 4.5.4 does not     properly traverse a mount propagation tree in a certain     case involving a slave mount, which allows local users     to cause a denial of service (NULL pointer dereference     and OOPS) via a crafted series of mount system     calls.(CVE-2016-4581)

  - Use after free vulnerability was found in percpu using     previously allocated memory in bpf. First
    __alloc_percpu_gfp() is called, then the memory is     freed with free_percpu() which triggers async     pcpu_balance_work and then pcpu_extend_area_map could     use a chunk after it has been freed.(CVE-2016-4794)

  - Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     before 4.5.2 allows local users to cause a denial of     service (memory corruption and system crash, or     spinlock) or possibly have unspecified other impact by     removing a network namespace, related to the     ppp_register_net_channel and ppp_unregister_channel     functions.(CVE-2016-4805)

  - A vulnerability was found in the Linux kernel. Payloads     of NM entries are not supposed to contain NUL. When     such entry is processed, only the part prior to the     first NUL goes into the concatenation (i.e. the     directory entry name being encoded by a bunch of NM     entries). The process stops when the amount collected     so far + the claimed amount in the current NM entry     exceed 254. However, the value returned as the total     length is the sum of *claimed* sizes, not the actual     amount collected. And that's what will be passed to     readdir() callback as the name length - 8Kb
    __copy_to_user() from a buffer allocated by
    __get_free_page().(CVE-2016-4913)

  - A flaw was discovered in processing setsockopt for 32     bit processes on 64 bit systems. This flaw will allow     attackers to alter arbitrary kernel memory when     unloading a kernel module. This action is usually     restricted to root-privileged users but can also be     leveraged if the kernel is compiled with CONFIG_USER_NS     and CONFIG_NET_NS and the user is granted elevated     privileges.(CVE-2016-4997)

  - An out-of-bounds heap memory access leading to a Denial     of Service, heap disclosure, or further impact was     found in setsockopt(). The function call is normally     restricted to root, however some processes with     cap_sys_admin may also be able to trigger this flaw in     privileged container environments.(CVE-2016-4998)

  - A race condition was found in the way the Linux     kernel's memory subsystem handled the copy-on-write     (COW) breakage of private read-only memory mappings. An     unprivileged, local user could use this flaw to gain     write access to otherwise read-only memory mappings and     thus increase their privileges on the     system.(CVE-2016-5195)

  - It was found that the RFC 5961 challenge ACK rate     limiting as implemented in the Linux kernel's     networking subsystem allowed an off-path attacker to     leak certain information about a given connection by     creating congestion on the global challenge ACK rate     limit counter and then measuring the changes by probing     packets. An off-path attacker could use this flaw to     either terminate TCP connection and/or inject payload     into non-secured TCP connection between two endpoints     on the network.(CVE-2016-5696)

  - A heap-based buffer overflow vulnerability was found in     the Linux kernel's hiddev driver. This flaw could allow     a local attacker to corrupt kernel memory, possible     privilege escalation or crashing the     system.(CVE-2016-5829)

  - When creating audit records for parameters to executed     children processes, an attacker can convince the Linux     kernel audit subsystem can create corrupt records which     may allow an attacker to misrepresent or evade logging     of executing commands.(CVE-2016-6136)

  - It was found that the unlink and rename functionality     in overlayfs did not verify the upper dentry for     staleness. A local, unprivileged user could use the     rename syscall on overlayfs on top of xfs to panic or     crash the system.(CVE-2016-6197)

  - A flaw was found that the vfs_rename() function did not     detect hard links on overlayfs. A local, unprivileged     user could use the rename syscall on overlayfs on top     of xfs to crash the system.(CVE-2016-6198)

  - System using the infiniband support module ib_srpt were     vulnerable to a denial of service by system crash by a     local attacker who is able to abort writes to a device     using this initiator.(CVE-2016-6327)

  - A race condition flaw was found in the ioctl_send_fib()     function in the Linux kernel's aacraid implementation.
    A local attacker could use this flaw to cause a denial     of service (out-of-bounds access or system crash) by     changing a certain size value.(CVE-2016-6480)

  - kernel/events/core.c in the performance subsystem in     the Linux kernel before 4.0 mismanages locks during     certain migrations, which allows local users to gain     privileges via a crafted application, aka Android     internal bug 30955111.(CVE-2016-6786)

  - kernel/events/core.c in the performance subsystem in     the Linux kernel before 4.0 mismanages locks during     certain migrations, which allows local users to gain     privileges via a crafted application, aka Android     internal bug 31095224.(CVE-2016-6787)

  - A use-after-free vulnerability was found in     tcp_xmit_retransmit_queue and other tcp_* functions.
    This condition could allow an attacker to send an     incorrect selective acknowledgment to existing     connections, possibly resetting a     connection.(CVE-2016-6828)

  - Linux kernel built with the 802.1Q/802.1ad     VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local     Area Network(CONFIG_VXLAN) with Transparent Ethernet     Bridging(TEB) GRO support, is vulnerable to a stack     overflow issue. It could occur while receiving large     packets via GRO path, as an unlimited recursion could     unfold in both VLAN and TEB modules, leading to a stack     corruption in the kernel.(CVE-2016-7039)

  - It was found that when the gcc stack protector was     enabled, reading the /proc/keys file could cause a     panic in the Linux kernel due to stack corruption. This     happened because an incorrect buffer size was used to     hold a 64-bit timeout value rendered as     weeks.(CVE-2016-7042)

  - It was found that when file permissions were modified     via chmod and the user modifying them was not in the     owning group or capable of CAP_FSETID, the setgid bit     would be cleared. 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     could allow a local user to gain group privileges via     certain setgid applications.(CVE-2016-7097)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Use-after-free vulnerability in mm/percpu.c in the Linux kernel through 4.6 allows local users to cause a     denial of service (BUG) or possibly have unspecified other impact via crafted use of the mmap and bpf     system calls. (CVE-2016-4794)

Note that Nessus relies on the presence of the package as reported by the vendor.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Security Fix(es) :

  - It was found that the Linux kernel's IPv6 implementation     mishandled socket options. A local attacker could abuse     concurrent access to the socket options to escalate     their privileges, or cause a denial of service     (use-after-free and system crash) via a crafted sendmsg     system call. (CVE-2016-3841, Important)

(CVE-2013-4312, CVE-2015-8374, CVE-2015-8543, CVE-2015-8812, CVE-2015-8844, CVE-2015-8845, CVE-2016-2053, CVE-2016-2069, CVE-2016-2847, CVE-2016-3156, CVE-2016-4581, CVE-2016-4794, CVE-2016-5412, CVE-2016-5828, CVE-2016-5829, CVE-2016-6136, CVE-2016-6198, CVE-2016-6327, CVE-2016-6480, CVE-2015-8746, CVE-2015-8956, CVE-2016-2117, CVE-2016-2384, CVE-2016-3070, CVE-2016-3699, CVE-2016-4569, CVE-2016-4578)

Additional Changes :

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 Linux kernel, before version 4.14.3, is vulnerable     to a denial of service in     drivers/md/dm.c:dm_get_from_kobject() which can be     caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM     devices. Only privileged local users (with     CAP_SYS_ADMIN capability) can directly perform the     ioctl operations for dm device creation and removal and     this would typically be outside the direct control of     the unprivileged attacker.(CVE-2017-18203i1/4%0

  - 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 through 3.18.1 uses     an incorrect length field during a calculation of an     amount of memory, which allows remote attackers to     cause a denial of service (mesh-node system crash) via     fragmented packets.(CVE-2014-9428i1/4%0

  - The regulator_ena_gpio_free function in     drivers/regulator/core.c in the Linux kernel allows     local users to gain privileges or cause a denial of     service (use-after-free) via a crafted     application.(CVE-2014-9940i1/4%0

  - The Linux kernel before 3.12, when UDP Fragmentation     Offload (UFO) is enabled, does not properly initialize     certain data structures, which allows local users to     cause a denial of service (memory corruption and system     crash) or possibly gain privileges via a crafted     application that uses the UDP_CORK option in a     setsockopt system call and sends both short and long     packets, related to the ip_ufo_append_data function in     net/ipv4/ip_output.c and the ip6_ufo_append_data     function in net/ipv6/ip6_output.c.(CVE-2013-4470i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's Datagram Congestion Control Protocol (DCCP)     implementation freed SKB (socket buffer) resources for     a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO     option is set on the socket. A local, unprivileged user     could use this flaw to alter the kernel memory,     allowing them to escalate their privileges on the     system.(CVE-2017-6074i1/4%0

  - A NULL-pointer dereference vulnerability was found in     the Linux kernel's TCP stack, in     net/netfilter/nf_nat_redirect.c in the     nf_nat_redirect_ipv4() function. A remote,     unauthenticated user could exploit this flaw to create     a system crash (denial of service).(CVE-2015-8787i1/4%0

  - A use-after-free flaw was found in the CXGB3 kernel     driver when the network was considered to be congested.
    The kernel incorrectly misinterpreted the congestion as     an error condition and incorrectly freed or cleaned up     the socket buffer (skb). When the device then sent the     skb's queued data, these structures were referenced. A     local attacker could use this flaw to panic the system     (denial of service) or, with a local account, escalate     their privileges.(CVE-2015-8812i1/4%0

  - A flaw was found in the way the Linux kernel's     networking implementation handled UDP packets with     incorrect checksum values. A remote attacker could     potentially use this flaw to trigger an infinite loop     in the kernel, resulting in a denial of service on the     system, or cause a denial of service in applications     using the edge triggered epoll     functionality.(CVE-2015-5364i1/4%0

  - The timer_create syscall implementation in     kernel/time/posix-timers.c in the Linux kernel doesn't     properly validate the sigevent-i1/4zsigev_notify field,     which leads to out-of-bounds access in the show_timer     function.(CVE-2017-18344i1/4%0

  - A flaw was discovered in the way the Linux kernel dealt     with paging structures. When the kernel invalidated a     paging structure that was not in use locally, it could,     in principle, race against another CPU that is     switching to a process that uses the paging structure     in question. A local user could use a thread running     with a stale cached virtual-i1/4zphysical translation to     potentially escalate their privileges if the     translation in question were writable and the physical     page got reused for something critical (for example, a     page table).(CVE-2016-2069i1/4%0

  - Use after free vulnerability was found in percpu using     previously allocated memory in bpf. First
    __alloc_percpu_gfp() is called, then the memory is     freed with free_percpu() which triggers async     pcpu_balance_work and then pcpu_extend_area_map could     use a chunk after it has been freed.(CVE-2016-4794i1/4%0

  - A missing authorization check in the     fscrypt_process_policy function in fs/crypto/policy.c     in the ext4 and f2fs filesystem encryption support in     the Linux kernel allows a user to assign an encryption     policy to a directory owned by a different user,     potentially creating a denial of     service.(CVE-2016-10318i1/4%0

  - The security_context_to_sid_core function in     security/selinux/ss/services.c in the Linux kernel     before 3.13.4 allows local users to cause a denial of     service (system crash) by leveraging the CAP_MAC_ADMIN     capability to set a zero-length security     context.(CVE-2014-1874i1/4%0

  - The vfe31_proc_general function in     drivers/media/video/msm/vfe/msm_vfe31.c in the     MSM-VFE31 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 a     certain id value, which allows attackers to gain     privileges or cause a denial of service (memory     corruption) via an application that makes a crafted     ioctl call.(CVE-2014-9410i1/4%0

  - A vulnerability was found in the Key Management sub     component of the Linux kernel, where when trying to     issue a KEYTCL_READ on a negative key would lead to a     NULL pointer dereference. A local attacker could use     this flaw to crash the kernel.(CVE-2017-12192i1/4%0

  - Out-of-bounds memory read in the x509_decode_time     function in x509_cert_parser.c in Linux kernels 4.3-rc1     and after.(CVE-2015-5327i1/4%0

  - It was found that the espfix functionality does not     work for 32-bit KVM paravirtualized guests. A local,     unprivileged guest user could potentially use this flaw     to leak kernel stack addresses.(CVE-2014-8134i1/4%0

  - An out-of-bounds write flaw was found in the way the     Apple Magic Mouse/Trackpad multi-touch driver handled     Human Interface Device (HID) reports with an invalid     size. An attacker with physical access to the system     could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-3181i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's key management subsystem handled keyring     object reference counting in certain error path of the     join_session_keyring() function. A local, unprivileged     user could use this flaw to escalate their privileges     on the system.(CVE-2016-0728i1/4%0

  - Use-after-free vulnerability in the skb_segment     function in net/core/skbuff.c in the Linux kernel     through 3.13.6 allows attackers to obtain sensitive     information from kernel memory by leveraging the     absence of a certain orphaning     operation.(CVE-2014-0131i1/4%0

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3053-1 advisory.

    A missing permission check when settings ACLs was discovered in nfsd. A local user could exploit this flaw     to gain access to any file by setting an ACL. (CVE-2016-1237)

    It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was     initialized before referencing it after an error condition occurred. A local attacker could use this to     cause a denial of service (system crash). (CVE-2016-4470)

    Sasha Levin discovered that a use-after-free existed in the percpu allocator in the Linux kernel. A local     attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code     with administrative privileges. (CVE-2016-4794)

    Kangjie Lu discovered an information leak in the netlink implementation of the Linux kernel. A local     attacker could use this to obtain sensitive information from kernel memory. (CVE-2016-5243)
