| Descripción: | Summary:
The remote host is missing an update for the Huawei EulerOS 'kernel' package(s) announced via the EulerOS-SA-2019-1538 advisory.
Vulnerability Insight:
The walk_hugetlb_range() function in 'mm/pagewalk.c' file in the Linux kernel from v4.0-rc1 through v4.15-rc1 mishandles holes in hugetlb ranges. This allows local users to obtain sensitive information from uninitialized kernel memory via crafted use of the mincore() system call.(CVE-2017-16994)
In the Linux kernel before 4.7, the amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function, leading to a double free.(CVE-2017-18174)
In the Linux kernel through 4.20.11, af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr.(CVE-2019-8912)
A security flaw was found in the Linux kernel that an attempt to move page mapped by AIO ring buffer to the other node triggers NULL pointer dereference at trace_writeback_dirty_page(), because aio_fs_backing_dev_info.dev is 0.(CVE-2016-3070)
The NFSv4 implementation in the Linux kernel through 4.11.1 allows local users to cause a denial of service (resource consumption) by leveraging improper channel callback shutdown when unmounting an NFSv4 filesystem, aka a 'module reference and kernel daemon' leak.(CVE-2017-9059)
When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.(CVE-2016-6136)
A use-after-free vulnerability was found in a network namespaces code affecting the Linux kernel since v4.0-rc1 through v4.15-rc5. The function get_net_ns_by_id() does not check for the net::count value after it has found a peer network in netns_ids idr which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user 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 thought to be unlikely.(CVE-2017-15129)
A NULL pointer dereference flaw was found in the rds_ib_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system.(CVE-2013-7339)
A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key.(CVE-2016-8650)
The uio_mmap_physical function in drivers/uio/uio.c in the Linux kernel before 3.12 does not validate the size of a memory block, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via crafted mmap operations, a different vulnerability than CVE-2013-4511.(CVE-2013-6763)
