The udf_read_inode function in fs/udf/inode.c in the Linux kernel before 3.19.1 does not validate certain length values, which allows local users to cause a denial of service (incorrect data representation or integer overflow, and OOPS) via a crafted UDF filesystem.

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 ims_pcu_get_cdc_union_desc function in     drivers/input/misc/ims-pcu.c in the Linux kernel,     through 4.13.11, allows local users to cause a denial     of service (ims_pcu_parse_cdc_data out-of-bounds read     and system crash) or possibly have unspecified other     impact via a crafted USB device.(CVE-2017-16645i1/4%0

  - It was found that due to excessive files_lock locking,     a soft lockup could be triggered in the Linux kernel     when performing asynchronous I/O operations. A local,     unprivileged user could use this flaw to crash the     system.(CVE-2014-8172i1/4%0

  - 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-2015-4177i1/4%0

  - A flaw was found in the way the Linux kernel's floppy     driver handled user space provided data in certain     error code paths while processing FDRAWCMD IOCTL     commands. A local user with write access to /dev/fdX     could use this flaw to free (using the kfree()     function) arbitrary kernel memory. (CVE-2014-1737,     Important) was found that the Linux kernel's floppy     driver leaked internal kernel memory addresses to user     space during the processing of the FDRAWCMD IOCTL     command. A local user with write access to /dev/fdX     could use this flaw to obtain information about the     kernel heap arrangement. (CVE-2014-1738, Low)Note: A     local user with write access to /dev/fdX could use     these two flaws (CVE-2014-1737 in combination with     CVE-2014-1738) to escalate their privileges on the     system.(CVE-2014-1738i1/4%0

  - 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-2017-7487i1/4%0

  - 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-2015-4167i1/4%0

  - Double free vulnerability in the ioctx_alloc function     in fs/aio.c in the Linux kernel before 3.12.4 allows     local users to cause a denial of service (system crash)     or possibly have unspecified other impact via vectors     involving an error condition in the aio_setup_ring     function.(CVE-2013-7348i1/4%0

  - A flaw was found in the Linux kernel's implementation     of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt()     system call. Users with non-namespace CAP_NET_ADMIN are     able to trigger this call and create a situation in     which the sockets sendbuff data size could be negative.
    This could adversely affect memory allocations and     create situations where the system could crash or cause     memory corruption.(CVE-2016-9793i1/4%0

  - Use-after-free vulnerability in the     ffs_user_copy_worker function in     drivers/usb/gadget/function/f_fs.c in the Linux kernel     before 4.5.3 allows local users to gain privileges by     accessing an I/O data structure after a certain     callback call. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.(CVE-2016-7912i1/4%0

  - A flaw was found in the way the get_dumpable() function     return value was interpreted in the ptrace subsystem of     the Linux kernel. When 'fs.suid_dumpable' was set to 2,     a local, unprivileged local user could use this flaw to     bypass intended ptrace restrictions and obtain     potentially sensitive information.(CVE-2013-2929i1/4%0

  - A DoS flaw was found for a Linux kernel built for the     x86 architecture which had the KVM virtualization     support(CONFIG_KVM) enabled.

  - The intr function in sound/oss/msnd_pinnacle.c in the     Linux kernel through 4.11.7 allows local users to cause     a denial of service (over-boundary access) or possibly     have unspecified other impact by changing the value of     a message queue head pointer between two kernel reads     of that value, aka a 'double fetch'     vulnerability.(CVE-2017-9986i1/4%0

  - sound/soc/msm/qdsp6v2/msm-audio-effects-q6-v2.c in the     MSM QDSP6 audio driver for the Linux kernel 3.x, as     used in Qualcomm Innovation Center (QuIC) Android     contributions for MSM devices and other products,     allows attackers to cause a denial of service (buffer     over-read) or possibly have unspecified other impact     via a crafted application that makes an ioctl call     specifying many commands.(CVE-2016-2064i1/4%0

  - The digi_port_init function in     drivers/usb/serial/digi_acceleport.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-2016-3140i1/4%0

  - In the Linux kernel through 4.14.13, the     rds_cmsg_atomic function in net/rds/rdma.c mishandles     cases where page pinning fails or an invalid address is     supplied, leading to an rds_atomic_free_op NULL pointer     dereference.(CVE-2018-5333i1/4%0

  - Multiple buffer underflows in the XFS implementation in     the Linux kernel through 3.12.1 allow local users to     cause a denial of service (memory corruption) or     possibly have unspecified other impact by leveraging     the CAP_SYS_ADMIN capability for a (1)     XFS_IOC_ATTRLIST_BY_HANDLE or (2)     XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted     length value, related to the xfs_attrlist_by_handle     function in fs/xfs/xfs_ioctl.c and the     xfs_compat_attrlist_by_handle function in     fs/xfs/xfs_ioctl32.c.(CVE-2013-6382i1/4%0

  - In the Linux kernel through 5.0.2, the function     inotify_update_existing_watch() in     fs/notify/inotify/inotify_user.c neglects to call     fsnotify_put_mark() with IN_MASK_CREATE after     fsnotify_find_mark(), which will cause a memory leak     (aka refcount leak). Finally, this will cause a denial     of service.(CVE-2019-9857i1/4%0

  - It was found that stacking a file system over procfs in     the Linux kernel could lead to a kernel stack overflow     due to deep nesting, as demonstrated by mounting     ecryptfs over procfs and creating a recursion by     mapping /proc/environ. An unprivileged, local user     could potentially use this flaw to escalate their     privileges on the system.(CVE-2016-1583i1/4%0

  - 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-2016-5829i1/4%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-2015-2666)

  - 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.

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-3658 advisory.

  - The ping_unhash function in net/ipv4/ping.c in the Linux kernel through 4.10.8 is too late in obtaining a     certain lock and consequently cannot ensure that disconnect function calls are safe, which allows local     users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a     socket system call. (CVE-2017-2671)

  - The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM     protection mechanism, which allows local users to read or write to kernel memory locations in the first     megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file,     related to arch/x86/mm/init.c and drivers/char/mem.c. (CVE-2017-7889)

  - The bio_map_user_iov and bio_unmap_user functions in block/bio.c in the Linux kernel before 4.13.8 do     unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page.
    The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a     memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk     is passed through to a virtual machine) due to an out-of-memory condition. (CVE-2017-12190)

  - The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is     consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain     privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a     race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.
    (CVE-2014-9710)

  - net/socket.c in the Linux kernel 3.19 before 3.19.3 does not validate certain range data for (1) sendto     and (2) recvfrom system calls, which allows local users to gain privileges by leveraging a subsystem that     uses the copy_from_iter function in the iov_iter interface, as demonstrated by the Bluetooth subsystem.
    (CVE-2015-2686)

  - The IPv4 implementation in the Linux kernel before 3.18.8 does not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allows remote     attackers to cause a denial of service (memory consumption or system crash) via a flood of packets.
    (CVE-2015-1465)

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

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

  - CVE-2015-3290     Andy Lutomirski discovered that the Linux kernel does     not properly handle nested NMIs. A local, unprivileged     user could use this flaw for privilege escalation.

  - CVE-2015-3291     Andy Lutomirski discovered that under certain conditions     a malicious userspace program can cause the kernel to     skip NMIs leading to a denial of service.

  - CVE-2015-4167     Carl Henrik Lunde discovered that the UDF implementation     is missing a necessary length check. A local user that     can mount devices could use this flaw to crash the     system.

  - CVE-2015-5157     Petr Matousek and Andy Lutomirski discovered that an NMI     that interrupts userspace and encounters an IRET fault     is incorrectly handled. A local, unprivileged user could     use this flaw for denial of service or possibly for     privilege escalation.

  - CVE-2015-5364     It was discovered that the Linux kernel does not     properly handle invalid UDP checksums. A remote attacker     could exploit this flaw to cause a denial of service     using a flood of UDP packets with invalid checksums.

  - CVE-2015-5366     It was discovered that the Linux kernel does not     properly handle invalid UDP checksums. A remote attacker     can cause a denial of service against applications that     use epoll by injecting a single packet with an invalid     checksum.

A race condition was discovered in the Linux kernel's file_handle size verification. A local user could exploit this flaw to read potentially sensative memory locations. (CVE-2015-1420)

A underflow error was discovered in the Linux kernel's Ozmo Devices USB over WiFi host controller driver. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially execute arbitrary code via a specially crafted packet. (CVE-2015-4001)

A bounds check error was discovered in the Linux kernel's Ozmo Devices USB over WiFi host controller driver. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially execute arbitrary code via a specially crafted packet. (CVE-2015-4002)

(CVE-2015-4003)

Carl H Lunde discovered missing sanity checks in the the Linux kernel's UDF file system (CONFIG_UDF_FS). A local attacker could exploit this flaw to cause a denial of service (system crash) by using a corrupted file system image. (CVE-2015-4167)

Daniel Borkmann reported a kernel crash in the Linux kernel's BPF filter JIT optimization. A local attacker could exploit this flaw to cause a denial of service (system crash). (CVE-2015-4700).

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

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2664-1 advisory.

  - Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows     local users to bypass intended size restrictions and trigger read operations on additional memory     locations by changing the handle_bytes value of a file handle during the execution of this function.
    (CVE-2015-1420)

  - Integer signedness error in the oz_hcd_get_desc_cnf function in drivers/staging/ozwpan/ozhcd.c in the     OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service     (system crash) or possibly execute arbitrary code via a crafted packet. (CVE-2015-4001)

  - drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 does not ensure     that certain length values are sufficiently large, which allows remote attackers to cause a denial of     service (system crash or large loop) or possibly execute arbitrary code via a crafted packet, related to     the (1) oz_usb_rx and (2) oz_usb_handle_ep_data functions. (CVE-2015-4002)

  - The oz_usb_handle_ep_data function in drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux     kernel through 4.0.5 allows remote attackers to cause a denial of service (divide-by-zero error and system     crash) via a crafted packet. (CVE-2015-4003)

  - The udf_read_inode function in fs/udf/inode.c in the Linux kernel before 3.19.1 does not validate certain     length values, which allows local users to cause a denial of service (incorrect data representation or     integer overflow, and OOPS) via a crafted UDF filesystem. (CVE-2015-4167)

  - The bpf_int_jit_compile function in arch/x86/net/bpf_jit_comp.c in the Linux kernel before 4.0.6 allows     local users to cause a denial of service (system crash) by creating a packet filter and then loading     crafted BPF instructions that trigger late convergence by the JIT compiler. (CVE-2015-4700)

  - Use-after-free vulnerability in the path_openat function in fs/namei.c in the Linux kernel 3.x and 4.x     before 4.0.4 allows local users to cause a denial of service or possibly have unspecified other impact via     O_TMPFILE filesystem operations that leverage a duplicate cleanup operation. (CVE-2015-5706)

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

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2663-1 advisory.

  - The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is     consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain     privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a     race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.
    (CVE-2014-9710)

  - Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows     local users to bypass intended size restrictions and trigger read operations on additional memory     locations by changing the handle_bytes value of a file handle during the execution of this function.
    (CVE-2015-1420)

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

  - CVE-2015-1805     Red Hat discovered that the pipe iovec read and write     implementations may iterate over the iovec twice but     will modify the iovec such that the second iteration     accesses the wrong memory. A local user could use this     flaw to crash the system or possibly for privilege     escalation. This may also result in data corruption and     information leaks in pipes between non-malicious     processes.

  - CVE-2015-3636     Wen Xu and wushi of KeenTeam discovered that users     allowed to create ping sockets can use them to crash the     system and, on 32-bit architectures, for privilege     escalation. However, by default, no users on a Debian     system have access to ping sockets.

  - CVE-2015-4167     Carl Henrik Lunde discovered that the UDF implementation     is missing a necessary length checks. A local user that     can mount devices could use this flaw to crash the     system.

The linux-2.6 update issued as DLA-246-1 caused regressions. This update corrects the defective patches applied in that update causing these problems. For reference the original advisory text follows.

This update fixes the CVEs described below.

CVE-2011-5321

Jiri Slaby discovered that tty_driver_lookup_tty() may leak a reference to the tty driver. A local user could use this flaw to crash the system.

CVE-2012-6689

Pablo Neira Ayuso discovered that non-root user-space processes can send forged Netlink notifications to other processes. A local user could use this flaw for denial of service or privilege escalation.

CVE-2014-3184

Ben Hawkes discovered that various HID drivers may over-read the report descriptor buffer, possibly resulting in a crash if a HID with a crafted descriptor is plugged in.

CVE-2014-8159

It was found that the Linux kernel's InfiniBand/RDMA subsystem did not properly sanitize input parameters while registering memory regions from user space via the (u)verbs API. A local user with access to a /dev/infiniband/uverbsX device could use this flaw to crash the system or, potentially, escalate their privileges on the system.

CVE-2014-9683

Dmitry Chernenkov discovered that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding, resulting in local denial of service.

CVE-2014-9728 / CVE-2014-9729 / CVE-2014-9730 / CVE-2014-9731 / CVE-2015-4167

Carl Henrik Lunde discovered that the UDF implementation is missing several necessary length checks. A local user that can mount devices could use these various flaws to crash the system, to leak information from the kernel, or possibly for privilege escalation.

CVE-2015-1805

Red Hat discovered that the pipe iovec read and write implementations may iterate over the iovec twice but will modify the iovec such that the second iteration accesses the wrong memory. A local user could use this flaw to crash the system or possibly for privilege escalation.
This may also result in data corruption and information leaks in pipes between non-malicious processes.

CVE-2015-2041

Sasha Levin discovered that the LLC subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this possibly allows privilege escalation from a process with CAP_NET_ADMIN capability; it also results in a trivial information leak.

CVE-2015-2042

Sasha Levin discovered that the RDS subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this results in a trivial information leak.

CVE-2015-2830

Andrew Lutomirski discovered that when a 64-bit task on an amd64 kernel makes a fork(2) or clone(2) system call using int $0x80, the 32-bit compatibility flag is set (correctly) but is not cleared on return. As a result, both seccomp and audit will misinterpret the following system call by the task(s), possibly leading to a violation of security policy.

CVE-2015-2922

Modio AB discovered that the IPv6 subsystem would process a router advertisement that specifies no route but only a hop limit, which would then be applied to the interface that received it. This can result in loss of IPv6 connectivity beyond the local network.

This may be mitigated by disabling processing of IPv6 router advertisements if they are not needed: sysctl net.ipv6.conf.default.accept_ra=0 sysctl net.ipv6.conf.<interface>.accept_ra=0

CVE-2015-3339

It was found that the execve(2) system call can race with inode attribute changes made by chown(2). Although chown(2) clears the setuid/setgid bits of a file if it changes the respective owner ID, this race condition could result in execve(2) setting effective uid/gid to the new owner ID, a privilege escalation.

For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze12.

For the oldstable distribution (wheezy), these problems were fixed in linux version 3.2.68-1+deb7u1 or earlier, except for CVE-2015-1805 and CVE-2015-4167 which will be fixed soon.

For the stable distribution (jessie), these problems were fixed in linux version 3.16.7-ckt11-1 or earlier, except for CVE-2015-4167 which will be fixed later.

We recommend that you upgrade your linux-2.6 packages.
