Huawei EulerOS: Security Advisory for kernel (EulerOS-SA-2018-1132)

Published: 2020-01-23 11:14:39
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:L/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-2018-1132 advisory.

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

Technical Details:
ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access.(CVE-2018-7566) The do_get_mempolicy() function in mm/mempolicy.c in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service (DoS) or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.(CVE-2018-10675) The Linux kernel has an undefined behavior when an argument of INT_MIN is passed to the kernel/signal.c:kill_something_info() function. A local attacker may be able to exploit this to cause a denial of service.(CVE-2018-10124) A an integer overflow vulnerability was discovered in the Linux kernel, from version 3.4 through 4.15, in the drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function. An attacker with access to the udldrmfb driver could exploit this to obtain full read and write permissions on kernel physical pages, resulting in a code execution in kernel space.(CVE-2018-8781) The code in the drivers/scsi/libsas/sas_scsi_host.c file in the Linux kernel allow a physically proximate attacker to cause a memory leak in the ATA command queue and, thus, denial of service by triggering certain failure conditions.(CVE-2018-10021) A flaw was found in the Linux kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory.(CVE-2018-1068) A vulnerability was found in the Linux kernel's kernel/events/core.c:perf_cpu_time_max_percent_handler() function. Local privileged users could exploit this flaw to cause a denial of service due to integer overflow or possibly have unspecified other impact.(CVE-2017-18255) The kernel_wait4 function in kernel/exit.c in the Linux kernel, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service by triggering an attempted use of the -INT_MIN value.(CVE-2018-10087) A null pointer dereference in dccp_write_xmit() function in net/dccp/output.c in the Linux kernel allows a local user to cause a denial of service by a number of certain crafted system calls.(CVE-2018-1130) An address corruption flaw was discovered in the Linux kernel built with hardware breakpoint (CONFIG_HAVE_HW_BREAKPOINT) support. While modifying a h/w breakpoint via 'modify_user_hw_breakpoint' routine, an unprivileged user/process could use this flaw to crash the system kernel resulting in DoS OR to potentially escalate privileges on a the system.(CVE-2018-1000199)

Affected Versions:
'kernel' Linux Distribution Package(s) on Huawei EulerOS V2.0SP1.

Recommendations:
Please install the updated Linux Distribution Package(s).

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

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".
