Security Bulletin
Summary
IBM Flex System Chassis Management Module (CMM) has addressed the following vulnerabilities in NTP.
Vulnerability Details
CVEID: CVE-2018-7185
DESCRIPTION: NTP is vulnerable to a denial of service. By sending specially crafted packets, a remote authenticated attacker could exploit this vulnerability to reset authenticated interleaved association.
CVSS Base Score: 3.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/139783 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2018-7184
DESCRIPTION: NTP is vulnerable to a denial of service, caused by the failure of the interleaved symmetric mode to recover from bad state. By sending specially crafted packets, a remote authenticated attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 3.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/139784 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2018-7183
DESCRIPTION: NTP is vulnerable to a buffer overflow, caused by improper bounds checking by the decodearr function. By leveraging an ntpq query and sending a response with a crafted array, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 5.6
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/140092 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2018-7182
DESCRIPTION: NTP could allow a remote attacker to obtain sensitive information, caused by a leak in the ctl_getitem() function. By sending a specially crafted mode 6 packet, an attacker could exploit this vulnerability to read past the end of its buffer.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/139785 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
