Published: 2020-01-23 12:04:13
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:N/C:C/I:C/A:C

Summary:
The remote host is missing an update for the Huawei EulerOS 'kernel' Linux Distribution Package(s) announced via the EulerOS-SA-2019-1524 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add from setsockopt and bind on an AF_PACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier register action. Later, packet_release operates on only one of the two applicable linked lists. The attacker can achieve Program Counter control.(CVE-2018-18559 The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel before 4.12 does not flush the operand cache and causes a kernel stack dump. A local users could obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.(CVE-2017-11472 Race condition in net/packet/af_packet.c in the Linux kernel allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a multithreaded application that makes PACKET_FANOUT setsockopt system calls.(CVE-2017-6346 Multiple race conditions in ipc/shm.c in the Linux kernel before 3.12.2 allow local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted application that uses shmctl IPC_RMID operations in conjunction with other shm system calls.(CVE-2013-7026 An issue was discovered in the Linux kernel. A NULL pointer dereference and panic in hfsplus_lookup() in the fs/hfsplus/dir.c function can occur when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory.(CVE-2018-14617 The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint.(CVE-2016-2782 An information-exposure flaw was found in the Linux kernel where the pcpu_embed_first_chunk() function in mm/percpu.c allows local users to obtain kernel-object address information by reading the kernel log (dmesg). However, this address is not static and cannot be used to commit a further attack.(CVE-2018-5995 Buffer overflow in net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, allows remote attackers to cause a denial of service (memory corruption a ...

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
