udp.c in the Linux kernel before 4.5 allows remote attackers to execute arbitrary code via UDP traffic that triggers an unsafe second checksum calculation during execution of a recv system call with the MSG_PEEK flag.

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 kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):The uas driver in the     Linux kernel before 4.13.6 allows local users to cause     a denial of service (out-of-bounds read and system     crash), or possibly have unspecified other impacts via     a crafted USB device, related to     drivers/usb/storage/uas-detect.h and     drivers/usb/storage/uas.c.(CVE-2017-16530)The     implementation of big key management in     security/keys/big_key.c in the Linux kernel before     4.8.7 mishandles unsuccessful crypto registration in     conjunction with successful key-type registration,     which allows local users to cause a denial of service     (NULL pointer dereference and panic) or possibly have     unspecified other impact via a crafted application that     uses the big_key data type.(CVE-2016-9313)The Linux     kernel allows remote attackers to execute arbitrary     code via UDP traffic that triggers an unsafe second     checksum calculation during execution of a recv system     call with the MSG_PEEK flag. This may create a kernel     panic or memory corruption leading to privilege     escalation.(CVE-2016-10229)Buffer overflow in the     exitcode_proc_write function in     arch/um/kernel/exitcode.c in the Linux kernel before     3.12 allows local users to cause a denial of service or     possibly have unspecified other impact by leveraging     root privileges for a write operation.(CVE-2013-4512)It     was found that unsharing a mount namespace could allow     a user to see data beneath their restricted     namespace.(CVE-2014-9717)A divide-by-zero flaw was     discovered in the Linux kernel built with KVM     virtualization support(CONFIG_KVM). The flaw occurs in     the KVM module's Programmable Interval Timer(PIT)     emulation, when PIT counters for channel 1 or 2 are set     to zero(0) and a privileged user inside the guest     attempts to read these counters. A privileged guest     user with access to PIT I/O ports could exploit this     issue to crash the host kernel (denial of     service).(CVE-2015-7513)The ims_pcu_parse_cdc_data     function in drivers/input/misc/ims-pcu.c in the Linux     kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (system crash)     via a USB device without both a master and a slave     interface.(CVE-2016-3689)Stack-based buffer overflow in     the brcmf_cfg80211_start_ap() function in     'driverset/wireless/broadcom/brcm80211/brcmfmac/cfg8021     1.c' in the Linux kernel before 4.7.5 allows local     users to cause a denial of service (system crash) or     possibly have unspecified other impact via a long SSID     Information Element in a command to a Netlink     socket.(CVE-2016-8658)drivers/hid/hid-sony.c in the     Human Interface Device (HID) subsystem in the Linux     kernel through 3.11, when CONFIG_HID_SONY is enabled,     allows physically proximate attackers to cause a denial     of service (heap-based out-of-bounds write) via a     crafted device.(CVE-2013-2890)An issue where a provided     address with access_ok() is not checked was discovered     in i915_gem_execbuffer2_ioctl in     drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux     kernel through 4.19.13. A local attacker can craft a     malicious IOCTL function call to overwrite arbitrary     kernel memory, resulting in a Denial of Service or     privilege escalation.(CVE-2018-20669)It was found that     the permission checks performed by the Linux kernel     when a netlink message was received were not     sufficient. A local, unprivileged user could     potentially bypass these restrictions by passing a     netlink socket as stdout or stderr to a more privileged     process and altering the output of this     process.(CVE-2014-0181)An issue was discovered in the     XFS filesystem in fs/xfs/libxfs/xfs_attr_leaf.c in the     Linux kernel. A NULL pointer dereference may occur for     a corrupted xfs image after xfs_da_shrink_inode() is     called with a NULL bp. This can lead to a system crash     and a denial of service.(CVE-2018-13094)The     irda_setsockopt function in net/irda/af_irda.c in the     Linux kernel, through 4.16, allows local users to cause     a denial of service (due to a use-after-free of the     ias_object and a system crash) or possibly have     unspecified other impact by leveraging an AF_IRDA     socket.(CVE-2018-6555)The x86/fpu (Floating Point Unit)     subsystem in the Linux kernel, when a processor     supports the xsave feature but not the xsaves feature,     does not correctly handle attempts to set reserved bits     in the xstate header via the ptrace() or rt_sigreturn()     system call. This allows local users to read the FPU     registers of other processes on the system, related to     arch/x86/kernel/fpu/regset.c and     arch/x86/kernel/fpu/signal.c.(CVE-2017-15537)The     fst_get_iface function in driverset/wan/farsync.c in     the Linux kernel before 3.11.7 does not properly     initialize a certain data structure, which allows local     users to obtain sensitive information from kernel     memory by leveraging the CAP_NET_ADMIN capability for     an SIOCWANDEV ioctl call.(CVE-2014-1444)In the Linux     kernel, through 4.15.4, the floppy driver reveals the     addresses of kernel functions and global variables     using printk calls within the function show_floppy in     drivers/block/floppy.c. An attacker can read this     information from dmesg and use the addresses to find     the locations of kernel code and data and bypass kernel     security protections such as KASLR.(CVE-2018-7273)A     flaw in 'arch/arm64/kernel/sys.c' in the Linux kernel     allows local users to bypass the 'strict page     permissions' protection mechanism and modify the     system-call table and, consequently, gain privileges by     leveraging write access.(CVE-2015-8967)The Linux kernel     before 3.11 on ARM platforms, as used in Android before     2016-08-05 on Nexus 5 and 7 (2013) devices, does not     properly consider user-space access to the TPIDRURW     register, which allows local users to gain privileges     via a crafted application, aka Android internal bug     28749743 and Qualcomm internal bug     CR561044.(CVE-2014-9870)A NULL pointer dereference     security flaw was found in the Linux kernel in the     vcpu_scan_ioapic() function in arch/x86/kvm/x86.c. This     allows local users with certain privileges to cause a     denial of service via a crafted system call to the KVM     subsystem.(CVE-2018-19407)It was found that current     implementation of kl5kusb105 driver failed to detect     short transfers when attempting to read the line state     and logged the content of the uninitialized heap     transfer buffer.(CVE-2017-5549)

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

  - 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-2016-0728)

  - A flaw was found in the way the Linux kernel's ASN.1     DER decoder processed certain certificate files with     tags of indefinite length. A local, unprivileged user     could use a specially crafted X.509 certificate DER     file to crash the system or, potentially, escalate     their privileges on the system.(CVE-2016-0758)

  - The LIST_POISON feature in include/linux/poison.h in     the Linux kernel before 4.3, as used in Android 6.0.1     before 2016-03-01, does not properly consider the     relationship to the mmap_min_addr value, which makes it     easier for attackers to bypass a poison-pointer     protection mechanism by triggering the use of an     uninitialized list entry, aka Android internal bug     26186802, a different vulnerability than     CVE-2015-3636.(CVE-2016-0821)

  - The pagemap_open function in fs/proc/task_mmu.c in the     Linux kernel before 3.19.3, as used in Android 6.0.1     before 2016-03-01, allows local users to obtain     sensitive physical-address information by reading a     pagemap file, aka Android internal bug     25739721.(CVE-2016-0823)

  - The aio_mount function in fs/aio.c in the Linux kernel     does not properly restrict execute access, which makes     it easier for local users to bypass intended SELinux     W^X policy restrictions.(CVE-2016-10044)

  - It was found that the fix for CVE-2016-9576 was     incomplete: the Linux kernel's sg implementation did     not properly restrict write operations in situations     where the KERNEL_DS option is set. A local attacker to     read or write to arbitrary kernel memory locations or     cause a denial of service (use-after-free) by     leveraging write access to a /dev/sg     device.(CVE-2016-10088)

  - A use-after-free flaw was found in the Linux kernel     which enables a race condition in the L2TPv3 IP     Encapsulation feature. A local user could use this flaw     to escalate their privileges or crash the     system.(CVE-2016-10200)

  - Mounting a crafted EXT4 image read-only leads to an     attacker controlled memory corruption and     SLAB-Out-of-Bounds reads.(CVE-2016-10208)

  - The Linux kernel allows remote attackers to execute     arbitrary code via UDP traffic that triggers an unsafe     second checksum calculation during execution of a recv     system call with the MSG_PEEK flag. This may create a     kernel panic or memory corruption leading to privilege     escalation.(CVE-2016-10229)

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly maintain POSIX ACL     xattr data, which allows local users to gain privileges     by leveraging a group-writable setgid     directory.(CVE-2016-1575)

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly restrict the mount     namespace, which allows local users to gain privileges     by mounting an overlayfs filesystem on top of a FUSE     filesystem, and then executing a crafted setuid     program.(CVE-2016-1576)

  - A syntax vulnerability was discovered in the kernel's     ASN1.1 DER decoder, which could lead to memory     corruption or a complete local denial of service     through x509 certificate DER files. A local system user     could use a specially created key file to trigger     BUG_ON() in the public_key_verify_signature() function     (crypto/asymmetric_keys/public_key.c), to cause a     kernel panic and crash the system.(CVE-2016-2053)

  - 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-2016-2069)

  - A divide-by-zero vulnerability was found in a way the     kernel processes TCP connections. The error can occur     if a connection starts another cwnd reduction phase by     setting tp-i1/4zprior_cwnd to the current cwnd (0) in     tcp_init_cwnd_reduction(). A remote, unauthenticated     attacker could use this flaw to crash the kernel     (denial of service).(CVE-2016-2070)

  - It was discovered that the atl2_probe() function in the     Atheros L2 Ethernet driver in the Linux kernel     incorrectly enabled scatter/gather I/O. A remote     attacker could use this flaw to obtain potentially     sensitive information from the kernel     memory.(CVE-2016-2117)

  - The create_fixed_stream_quirk function in     sound/usb/quirks.c in the snd-usb-audio driver in the     Linux kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (NULL pointer     dereference or double free, and system crash) via a     crafted endpoints value in a USB device     descriptor.(CVE-2016-2184)

  - The ati_remote2_probe function in     drivers/input/misc/ati_remote2.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2185)

  - The powermate_probe function in     drivers/input/misc/powermate.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2186)

  - The gtco_probe function in drivers/input/tablet/gtco.c     in the Linux kernel through 4.5.2 allows physically     proximate attackers to cause a denial of service (NULL     pointer dereference and system crash) via a crafted     endpoints value in a USB device     descriptor.(CVE-2016-2187)

  - The iowarrior_probe function in     drivers/usb/misc/iowarrior.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (NULL pointer dereference and system     crash) via a crafted endpoints value in a USB device     descriptor.(CVE-2016-2188)

  - A flaw was found in the USB-MIDI Linux kernel driver: a     double-free error could be triggered for the 'umidi'     object. An attacker with physical access to the system     could use this flaw to escalate their     privileges.(CVE-2016-2384)

  - The snd_seq_ioctl_remove_events function in     sound/core/seq/seq_clientmgr.c in the Linux kernel     before 4.4.1 does not verify FIFO assignment before     proceeding with FIFO clearing, which allows local users     to cause a denial of service (NULL pointer dereference     and OOPS) via a crafted ioctl call.(CVE-2016-2543)

  - Race condition in the queue_delete function in     sound/core/seq/seq_queue.c in the Linux kernel before     4.4.1 allows local users to cause a denial of service     (use-after-free and system crash) by making an ioctl     call at a certain time.(CVE-2016-2544)

  - CVE-2017-1000363: Linux drivers/char/lp.c Out-of-Bounds     Write. Due to a missing bounds check, and the fact that     parport_ptr integer is static, a 'secure boot' kernel     command line adversary (can happen due to bootloader     vulns, e.g. Google Nexus 6's CVE-2016-10277, where due     to a vulnerability the adversary has partial control     over the command line) can overflow the parport_nr array     in the following code, by appending many (>LP_NO)     'lp=none' arguments to the command line (bnc#1039456).

  - CVE-2017-1000365: The Linux Kernel imposes a size     restriction on the arguments and environmental strings     passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the     size), but did not take the argument and environment     pointers into account, which allowed attackers to bypass     this limitation. (bnc#1039354).

  - CVE-2017-1000380: sound/core/timer.c in the Linux kernel     is vulnerable to a data race in the ALSA /dev/snd/timer     driver resulting in local users being able to read     information belonging to other users, i.e.,     uninitialized memory contents may be disclosed when a     read and an ioctl happen at the same time (bnc#1044125).

  - CVE-2017-10661: Race condition in fs/timerfd.c in the     Linux kernel allowed local users to gain privileges or     cause a denial of service (list corruption or     use-after-free) via simultaneous file-descriptor     operations that leverage improper might_cancel queueing     (bnc#1053152).

  - CVE-2017-11176: The mq_notify function in the Linux     kernel did not set the sock pointer to NULL upon entry     into the retry logic. During a user-space close of a     Netlink socket, it allowed attackers to cause a denial     of service (use-after-free) or possibly have unspecified     other impact (bnc#1048275).

  - CVE-2017-12153: A security flaw was discovered in the     nl80211_set_rekey_data() function in     net/wireless/nl80211.c in the Linux kernel This function     did not check whether the required attributes are     present in a Netlink request.

  - CVE-2017-8890: The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allowed attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call (bnc#1038544).

  - CVE-2017-8924: The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel allowed     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     (bnc#1037182 bsc#1038982).

  - CVE-2017-8925: The omninet_open function in     drivers/usb/serial/omninet.c in the Linux kernel allowed     local users to cause a denial of service (tty     exhaustion) by leveraging reference count mishandling     (bnc#1037183 bsc#1038981).

  - CVE-2017-9074: The IPv6 fragmentation implementation in     the Linux kernel did not consider that the nexthdr field     may be associated with an invalid option, which allowed     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 (bnc#1039882).

  - CVE-2017-9075: The sctp_v6_create_accept_sk function in     net/sctp/ipv6.c in the Linux kernel mishandled     inheritance, which allowed 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     (bnc#1039883).

  - CVE-2017-9076: The dccp_v6_request_recv_sock function in     net/dccp/ipv6.c in the Linux kernel mishandled     inheritance, which allowed 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     (bnc#1039885).

  - CVE-2017-9077: The tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c in the Linux kernel mishandled     inheritance, which allowed 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     (bnc#1040069).

  - CVE-2017-9242: The __ip6_append_data function in     net/ipv6/ip6_output.c in the Linux kernel is too late in     checking whether an overwrite of an skb data structure     may occur, which allowed local users to cause a denial     of service (system crash) via crafted system calls     (bnc#1041431).

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2017-0145 for details.

The version of Palo Alto Networks PAN-OS running on the remote host is 6.1.x prior to 6.1.18, 7.0.x prior to 7.0.17, 7.1.x prior to 7.1.12, or 8.0.x prior to 8.0.3. It is, therefore, affected by multiple vulnerabilities :

  - A denial of service vulnerability exists in the OpenSSL     component that is triggered when handling a large number     of consecutive 'SSL3_AL_WARNING' undefined alerts. An     unauthenticated, remote attacker can exploit this, by     continuously sending warning alerts, to exhaust     available CPU resources. Note that this vulnerability     does not affect the 8.0.x version branch.
    (CVE-2016-8610)

  - A remote code execution vulnerability exists in the     Linux kernel in udp.c due to an unsafe second checksum     calculation during execution of a recv system call with     the MSG_PEEK flag. An unauthenticated, remote attacker     can exploit this, via specially crafted UDP traffic, to     cause a denial of service condition or the execution of     arbitrary code. Note that this vulnerability does not     affect the 7.0.x version branch. (CVE-2016-10229)

  - A remote code execution vulnerability exists in the DNS     proxy service that is triggered when resolving fully     qualified domain names (FQDN). An unauthenticated,     remote attacker can exploit this to execute arbitrary     code. Note that this vulnerability was fixed in version     7.1.10 for the 7.1.x version branch. (CVE-2017-8390)

  - A XML external entity (XXE) vulnerability exists due to     an incorrectly configured XML parser accepting XML from     an untrusted source. An unauthenticated, remote attacker     can exploit this by sending specially crafted XML data     to the GlobalProtect external interface. Exploitation of     this vulnerability may allow disclosure of information,     denial of service or server side request forgery.
    (CVE-2017-9458)

  - A stored cross-site scripting (XSS) vulnerability exists     in the Firewall web interface due to improper validation     of user-supplied input before returning it to users. An     unauthenticated, remote attacker can exploit this, via a     specially crafted request, to execute arbitrary script     code in a user's browser session. (CVE-2017-9459)

  - A cross-site scripting (XSS) vulnerability exists in the     GlobalProtect component due to improper validation of     user-supplied input to unspecified request parameters.
    An unauthenticated, remote attacker can exploit this,     via a specially crafted request, to execute arbitrary     script code in a user's browser session.
    (CVE-2017-9467, CVE-2017-12416)

  - A denial of service vulnerability exists that is     triggered when the system attempts to close the     connection of a rogue client that ignored the URL     filtering block page. An unauthenticated, remote     attacker can exploit this to crash the interface. Note     that this vulnerability does not affect the 6.1.x and     7.0.x version branches.

Unsafe second checksum calculation in udp.c :

The Linux kernel allows remote attackers to execute arbitrary code via UDP traffic that triggers an unsafe second checksum calculation during execution of a recv system call with the MSG_PEEK flag. This may create a kernel panic or memory corruption leading to privilege escalation. (CVE-2016-10229)
