The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.


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

- The x25_recvmsg function in net/x25/af_x25.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call.(CVE-2013-7271i1/4%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 kernel would be vulnerable to a NULL pointer dereference flaw in Linux kernel's kvm_apic_has_events() function while doing an ioctl. An unprivileged user able to access the '/dev/kvm' device could use this flaw to crash the system kernel.(CVE-2015-4692i1/4%0

- 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

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