SynopsisThe remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.
DescriptionAccording 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 :
- A memory corruption flaw was found in the way the USB ConnectTech WhiteHEAT serial driver processed completion commands sent via USB Request Blocks buffers. 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'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-2015-2830i1/4%0
- A flaw was found in the way the Linux kernel's SCTP implementation validated INIT chunks when performing Address Configuration Change (ASCONF). A remote attacker could use this flaw to crash the system by sending a specially crafted SCTP packet to trigger a NULL pointer dereference on the system.(CVE-2014-7841i1/4%0
- A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) can use this issue to crash the system.(CVE-2017-1000111)
- A flaw was found in the way the Linux kernel performed forking inside of a transaction. A local, unprivileged user on a PowerPC system that supports transactional memory could use this flaw to crash the system.(CVE-2014-2673i1/4%0
- The hashbin_delete function in net/irda/irqueue.c in the Linux kernel improperly manages lock dropping, which allows local users to cause a denial of service (deadlock) via crafted operations on IrDA devices.(CVE-2017-6348i1/4%0
- An out-of-bounds flaw was found in the kernel, where the length of the sockaddr parameter was not checked in the pptp_bind() and pptp_connect() functions. As a result, more kernel memory was copied out than required, leaking information from the kernel stack (including kernel addresses). A local system user could exploit this flaw to bypass kernel ASLR or leak other information.(CVE-2015-8569i1/4%0
