Security Bulletin: Vulnerabilities in ntp affect IBM Integrated Management Module II (IMM2) for System x, Flex and BladeCenter Systems

Summary

IBM Integrated Management Module II (IMM2) for System x, Flex and BladeCenter Systems 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&gt; 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&gt; 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&gt; 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&gt; 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)
