Huawei EulerOS: Security Advisory for ntp (EulerOS-SA-2019-2215)

Published: 2020-01-23 12:40:10
CVE Author: NIST National Vulnerability Database (NVD)

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

Summary:
The remote host is missing an update for the Huawei EulerOS 'ntp' Linux Distribution Package(s) announced via the EulerOS-SA-2019-2215 advisory.

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

Technical Details:
NTP before 4.2.8p6 and 4.3.x before 4.3.90, when configured in broadcast mode, allows man-in-the-middle attackers to conduct replay attacks by sniffing the network.(CVE-2015-7973) ntpd in ntp before 4.2.8p3 with remote configuration enabled allows remote authenticated users with knowledge of the configuration password and access to a computer entrusted to perform remote configuration to cause a denial of service (service crash) via a NULL byte in a crafted configuration directive packet.(CVE-2015-5146) Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6 through 4.2.8p10 allows remote attackers to execute arbitrary code by leveraging an ntpq query and sending a response with a crafted array.(CVE-2018-7183) ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the 'received' timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704.(CVE-2018-7184)

Affected Versions:
'ntp' Linux Distribution Package(s) on Huawei EulerOS V2.0SP5.

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

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package
