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-2017-6464
Description: NTP is vulnerable to a denial of service. A remote authenticated attacker could exploit this vulnerability using a malformed mode configuration directive to cause the application to crash.
CVSS Base Score: 4.2
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/123610> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-6463
Description: NTP is vulnerable to a denial of service. By sending an invalid setting, a remote authenticated attacker could exploit this vulnerability using the :config directive to cause the daemon to crash.
CVSS Base Score: 4.2
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/123612> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-6462
Description: NTP is vulnerable to a denial of service, caused by a buffer overflow in the legacy Datum Programmable Time Server refclock driver. By sending specially crafted packets, a local authenticated attacker could exploit this vulnerability to overflow a buffer and cause a denial of service.
CVSS Base Score: 1.6
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/123611> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:P/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2017-6460
Description: NTP is vulnerable to a denial of service, caused by a stack-based buffer overflow in ntpq. By sending a specially crafted request, a remote authenticated attacker could overflow a buffer and cause the application to crash.
CVSS Base Score: 4.2
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/123618> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-6458
Description: NTP is vulnerable to a denial of service, caused by multiple buffer overflows in the ctl_put() functions. By sending an overly long string argument, a remote authenticated attacker could exploit this vulnerability to overflow a buffer and cause the application to crash.
CVSS Base Score: 4.2
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/123616> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-6451
Description: NTP could allow a local attacker to bypass security restrictions, caused by an out-of-bounds memory write when handling the return value of snprintf()/vsnprintf() functions. An attacker could exploit this vulnerability to overwrite a saved instruction pointer on the stack and gain control over the execution flow.
CVSS Base Score: 1.8
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/123617> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:N)
CVEID: CVE-2016-9042
Description: NTP is vulnerable to a denial of service, caused by an error in the origin timestamp check functionality. By sending specially crafted packets, a remote authenticated attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 4.4
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/123619> for the current score
CVSS Environmental Score*: Undefined
