The UDF filesystem implementation in the Linux kernel before 3.18.2 does not validate certain lengths, which allows local users to cause a denial of service (buffer over-read and system crash) via a crafted filesystem image, related to fs/udf/inode.c and fs/udf/symlink.c.

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 :

  - drivers/gpu/msm/kgsl.c in the MSM graphics driver (aka     GPU driver) for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, mishandles the     KGSL_MEMFLAGS_GPUREADONLY flag, which allows attackers     to gain privileges by leveraging accidental read-write     mappings, aka Qualcomm internal bug     CR988993.(CVE-2016-2067i1/4%0

  - Integer overflow in the mem_check_range function in     drivers/infiniband/sw/rxe/rxe_mr.c in the Linux kernel     before 4.9.10 allows local users to cause a denial of     service (memory corruption), obtain sensitive     information from kernel memory, or possibly have     unspecified other impact via a write or read request     involving the 'RDMA protocol over infiniband' (aka Soft     RoCE) technology.(CVE-2016-8636i1/4%0

  - Heap-based buffer overflow in the     logi_dj_ll_raw_request function in     drivers/hid/hid-logitech-dj.c in the Linux kernel     before 3.16.2 allows physically proximate attackers to     cause a denial of service (system crash) or possibly     execute arbitrary code via a crafted device that     specifies a large report size for an LED     report.(CVE-2014-3183i1/4%0

  - The futex_requeue function in kernel/futex.c in the     Linux kernel, before 4.14.15, might allow attackers to     cause a denial of service (integer overflow) or     possibly have unspecified other impacts by triggering a     negative wake or requeue value. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we believe it is     unlikely.(CVE-2018-6927i1/4%0

  - The hub_activate function in drivers/usb/core/hub.c in     the Linux kernel before 4.3.5 does not properly     maintain a hub-interface data structure, which allows     physically proximate attackers to cause a denial of     service (invalid memory access and system crash) or     possibly have unspecified other impact by unplugging a     USB hub device.(CVE-2015-8816i1/4%0

  - It was found that the blk_rq_map_user_iov() function in     the Linux kernel's block device implementation did not     properly restrict the type of iterator, which could     allow 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-2016-9576i1/4%0

  - A security flaw was found in the Linux kernel's     networking subsystem that destroying the network     interface with huge number of ipv4 addresses assigned     keeps 'rtnl_lock' spinlock for a very long time (up to     hour). This blocks many network-related operations,     including creation of new incoming ssh connections.The     problem is especially important for containers, as the     container owner has enough permissions to trigger this     and block a network access on a whole host, outside the     container.(CVE-2016-3156i1/4%0

  - 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-2017-8924i1/4%0

  - 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-2015-1465i1/4%0

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9728i1/4%0

  - net/ipv6/ip6_output.c in the Linux kernel through     3.11.4 does not properly determine the need for UDP     Fragmentation Offload (UFO) processing of small packets     after the UFO queueing of a large packet, which allows     remote attackers to cause a denial of service (memory     corruption and system crash) or possibly have     unspecified other impact via network traffic that     triggers a large response packet.(CVE-2013-4387i1/4%0

  - It was found that nfsd is missing permissions check     when setting ACL on files, this may allow a local users     to gain access to any file by setting a crafted     ACL.(CVE-2016-1237i1/4%0

  - In the Linux kernel before 4.13.5, a local user could     create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of     service.(CVE-2017-18270i1/4%0

  - An issue was discovered in the Linux kernel where an     integer overflow in kernel/time/posix-timers.c in the     POSIX timer code is caused by the way the overrun     accounting works. Depending on interval and expiry time     values, the overrun can be larger than INT_MAX, but the     accounting is int based. This basically makes the     accounting values, which are visible to user space via     timer_getoverrun(2) and siginfo::si_overrun,     random.(CVE-2018-12896i1/4%0

  - Since Linux kernel version 3.2, the mremap() syscall     performs TLB flushes after dropping pagetable locks. If     a syscall such as ftruncate() removes entries from the     pagetables of a task that is in the middle of mremap(),     a stale TLB entry can remain for a short time that     permits access to a physical page after it has been     released back to the page allocator and reused. This is     fixed in the following kernel versions: 4.9.135,     4.14.78, 4.18.16, 4.19.(CVE-2018-18281i1/4%0

  - The netfilter subsystem in the Linux kernel through     4.15.7 mishandles the case of a rule blob that contains     a jump but lacks a user-defined chain, which allows     local users to cause a denial of service (NULL pointer     dereference) by leveraging the CAP_NET_RAW or     CAP_NET_ADMIN capability, related to arpt_do_table in     net/ipv4/netfilter/arp_tables.c, ipt_do_table in     net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in     net/ipv6/netfilter/ip6_tables.c.(CVE-2018-1065i1/4%0

  - The use of a kzalloc with an integer multiplication     allowed an integer overflow condition to be reached in     vfio_pci_intrs.c. This combined with CVE-2016-9083 may     allow an attacker to craft an attack and use     unallocated memory, potentially crashing the     machine.(CVE-2016-9084i1/4%0

  - The acm_probe function in drivers/usb/class/cdc-acm.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 USB device     without both a control and a data endpoint     descriptor.(CVE-2016-3138i1/4%0

  - It was discovered that root can gain direct access to     an internal keyring, such as '.dns_resolver' in RHEL-7     or '.builtin_trusted_keys' upstream, by joining it as     its session keyring. This allows root to bypass module     signature verification by adding a new public key of     its own devising to the keyring.(CVE-2016-9604i1/4%0

  - An information leak flaw was found in the Linux     kernel's IEEE 802.11 wireless networking     implementation. When software encryption was used, a     remote attacker could use this flaw to leak up to 8     bytes of plaintext.(CVE-2014-8709i1/4%0

  - A flaw was found in the way the Linux kernel's Crypto     subsystem handled automatic loading of kernel modules.
    A local user could use this flaw to load any installed     kernel module, and thus increase the attack surface of     the running kernel.(CVE-2014-9644)

  - 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)

  - An integer overflow flaw was found in the way the Linux     kernel's netfilter connection tracking implementation     loaded extensions. An attacker on a local network could     potentially send a sequence of specially crafted     packets that would initiate the loading of a large     number of extensions, causing the targeted system in     that network to crash.(CVE-2014-9715)

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9728)

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9730)

  - A path length checking flaw 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 use this flaw to leak kernel memory     to user-space.(CVE-2014-9731)

  - The snd_compr_tstamp function in     sound/core/compress_offload.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 properly     initialize a timestamp data structure, which allows     attackers to obtain sensitive information via a crafted     application, aka Android internal bug 28770164 and     Qualcomm internal bug CR568717.(CVE-2014-9892)

  - drivers/media/media-device.c in the Linux kernel before     3.11, as used in Android before 2016-08-05 on Nexus 5     and 7 (2013) devices, does not properly initialize     certain data structures, which allows local users to     obtain sensitive information via a crafted application,     aka Android internal bug 28750150 and Qualcomm internal     bug CR570757, a different vulnerability than     CVE-2014-1739.(CVE-2014-9895)

  - 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-2014-9900)

  - The snd_compress_check_input function in     sound/core/compress_offload.c in the ALSA subsystem in     the Linux kernel before 3.17 does not properly check     for an integer overflow, which allows local users to     cause a denial of service (insufficient memory     allocation) or possibly have unspecified other impact     via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl     call.(CVE-2014-9904)

  - A race condition in the ip4_datagram_release_cb     function in net/ipv4/datagram.c in the Linux kernel     allows local users to gain privileges or cause a denial     of service (use-after-free) by leveraging incorrect     expectations about locking during multithreaded access     to internal data structures for IPv4 UDP     sockets.(CVE-2014-9914)

  - A flaw was discovered in the way the kernel allows     stackable filesystems to overlay. A local attacker who     is able to mount filesystems can abuse this flaw to     escalate privileges.(CVE-2014-9922)

  - It was found that the Linux kernel KVM subsystem's     sysenter instruction emulation was not sufficient. An     unprivileged guest user could use this flaw to escalate     their privileges by tricking the hypervisor to emulate     a SYSENTER instruction in 16-bit mode, if the guest OS     did not initialize the SYSENTER model-specific     registers (MSRs). Note: Certified guest operating     systems for Red Hat Enterprise Linux with KVM do     initialize the SYSENTER MSRs and are thus not     vulnerable to this issue when running on a KVM     hypervisor.(CVE-2015-0239)

  - A flaw was found in the way the Linux kernel's XFS file     system handled replacing of remote attributes under     certain conditions. A local user with access to XFS     file system mount could potentially use this flaw to     escalate their privileges on the system.(CVE-2015-0274)

  - A flaw was found in the way the Linux kernel's ext4     file system handled the 'page size i1/4z block size'     condition when the fallocate zero range functionality     was used. A local attacker could use this flaw to crash     the system.(CVE-2015-0275)

  - 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)

  - A use-after-free flaw was found in the way the Linux     kernel's SCTP implementation handled authentication key     reference counting during INIT collisions. A remote     attacker could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2015-1421)

  - 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)

  - A flaw was found in the way the nft_flush_table()     function of the Linux kernel's netfilter tables     implementation flushed rules that were referencing     deleted chains. A local user who has the CAP_NET_ADMIN     capability could use this flaw to crash the     system.(CVE-2015-1573)

  - An integer overflow flaw was found in the way the Linux     kernel randomized the stack for processes on certain     64-bit architecture systems, such as x86-64, causing     the stack entropy to be reduced by four.(CVE-2015-1593)

  - 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).

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.
