LOW Privileges required
LOW Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
The tipc_nl_publ_dump function in net/tipc/socket.c in the Linux kernel through 4.6 does not verify socket existence, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a dumpit operation.

NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-3016-1.NASL description Jesse Hertz and Tim Newsham discovered that the Linux netfilter implementation did not correctly perform validation when handling 32 bit compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A local unprivileged attacker could use this to cause a denial of service (system crash) or execute arbitrary code with administrative privileges. (CVE-2016-4997) Kangjie Lu discovered an information leak in the core USB implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4482) Kangjie Lu discovered an information leak in the timer handling implementation in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4569, CVE-2016-4578) Kangjie Lu discovered an information leak in the X.25 Call Request handling in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4580) It was discovered that an information leak exists in the Rock Ridge implementation in the Linux kernel. A local attacker who is able to mount a malicious iso9660 file system image could exploit this flaw to obtain potentially sensitive information from kernel memory. (CVE-2016-4913) Baozeng Ding discovered that the Transparent Inter-process Communication (TIPC) implementation in the Linux kernel did not verify socket existence before use in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-4951) Jesse Hertz and Tim Newsham discovered that the Linux netfilter implementation did not correctly perform validation when handling IPT_SO_SET_REPLACE events. A local unprivileged attacker could use this to cause a denial of service (system crash) or obtain potentially sensitive information from kernel memory. (CVE-2016-4998).

This flaw will allow attackers to alter arbitary kernel memory when unloading a kernel module. This action is usually restricted to root-priveledged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS. (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 vulnerability was found in the Linux kernel. The pointer to the netlink socket attribute is not checked, which could cause a NULL pointer dereference when parsing the nested attributes in function tipc_nl_publ_dump(). This allows local users to cause a DoS. (CVE-2016-4951) A double free vulnerability was found in netlink_dump, which could cause a denial of service or possibly other unspecified impact. (CVE-2016-9806) (Updated on 2016-07-14: CVE-2016-4998 and CVE-2016-4951 were fixed in this version, but was not previously listed in this errata.)

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-2014-3185i1/4%0 - Use-after-free vulnerability in the msm_set_crop function in drivers/media/video/msm/msm_camera.c in the MSM-Camera 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 gain privileges or cause a denial of service (memory corruption) via an application that makes a crafted ioctl call.(CVE-2015-0568i1/4%0 - The vivid_fb_ioctl function in drivers/media/platform/vivid/vivid-osd.c in the Linux kernel through 4.3.3 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory via a crafted application.(CVE-2015-7884i1/4%0 - The usb_get_bos_descriptor function in drivers/usb/core/config.c in the Linux kernel can allow a local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device.(CVE-2017-16535i1/4%0 - The ACPI parsing functionality in the Linux kernel does not flush the node and node_ext caches which causes a kernel stack dump. This allows local users to obtain sensitive information from kernel memory and use this information to bypass the KASLR protection mechanism by creating and applying crafted ACPI table.(CVE-2017-13694i1/4%0 - The is_ashmem_file function in drivers/staging/android/ashmem.c in a certain Qualcomm Innovation Center (QuIC) Android patch for the Linux kernel 3.x mishandles pointer validation within the KGSL Linux Graphics Module, which allows attackers to bypass intended access restrictions by using the /ashmem string as the dentry name.(CVE-2016-5340i1/4%0 - It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system.(CVE-2013-4312i1/4%0 - 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-2017-7541i1/4%0 - A flaw in the netback module allowed frontends to control mapping of requests to request queues. An attacker can change this mapping by requesting invalid mapping requests allowing the (usually privileged) backend to access out-of-bounds memory access for reading and writing.(CVE-2018-15471i1/4%0 - A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver firewire-net in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution.The flaw requires firewire-net module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network.(CVE-2016-8633i1/4%0 - It was found that the Linux kernel can hit a BUG_ON() statement in the __xfs_get_blocks() in the fs/xfs/xfs_aops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUG_ON() instead of an I/O failure. This allows a local unprivileged attacker to cause a system crash and a denial of service.(CVE-2016-10741i1/4%0 - A vulnerability was found in the Linux kernel. The pointer to the netlink socket attribute is not checked, which could cause a null pointer dereference when parsing the nested attributes in function tipc_nl_publ_dump(). This allows local users to cause a DoS.(CVE-2016-4951i1/4%0 - It was reported that with Linux kernel, earlier than version v4.10-rc8, an application may trigger a BUG_ON in sctp_wait_for_sndbuf if the socket tx buffer is full, a thread is waiting on it to queue more data, and meanwhile another thread peels off the association being used by the first thread.(CVE-2017-5986i1/4%0 - The kvm_vm_ioctl_check_extension function in arch/powerpc/kvm/powerpc.c in the Linux kernel before 4.13.11 allows local users to cause a denial of service (NULL pointer dereference and system crash) via a KVM_CHECK_EXTENSION KVM_CAP_PPC_HTM ioctl call to /dev/kvm.(CVE-2017-15306i1/4%0 - A flaw was found in the way the Linux kernel last seen 2020-03-19 modified 2019-05-14 plugin id 124970 published 2019-05-14 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/124970 title EulerOS Virtualization for ARM 64 3.0.1.0 : kernel (EulerOS-SA-2019-1517)
