IBM Chassis Management Module (CMM) has addressed the following vulnerabilities in NTP.
Summary
IBM Chassis Management Module (CMM) has addressed the following vulnerabilities in NTP.
Vulnerability Details:
CVEID: CVE-2016-7426
Description: NTP is vulnerable to a denial of service, caused by the improper handling of invalid server responses. By sending specially crafted packets with spoofed source address, a remote attacker could exploit this vulnerability to a denial of service.
CVSS Base Score: 1.6
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119094> 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-2016-7427
Description: NTP is vulnerable to a denial of service, caused by an error in broadcast mode replay prevention functionality. By sending specially crafted NTP packets, a local attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 4
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119088> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-7428
Description: NTP is vulnerable to a denial of service, caused by an error in broadcast mode poll interval enforcement functionality. By sending specially crafted NTP packets, a remote attacker from within the local network could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 4.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119089> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-7429
Description: NTP is vulnerable to a denial of service, caused by an attack on interface selection. By sending specially crafted packets with spoofed source address, a physical attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 1.6
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119093> 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-2016-7431
Description: NTP could allow a remote attacker to bypass security restrictions, caused by the improper handling of Zero origin timestamp checks. An attacker could exploit this vulnerability to launch further attacks on the system.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119091> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2016-7433
Description: NTP is vulnerable to a denial of service, caused by the inclusion of the root delay allowing for an incorrect root distance calculation. An attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 1.6
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119095> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:P/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-7434
Description: NTP is vulnerable to a denial of service, caused by a NULL pointer dereference in the _IO_str_init_static_internal() function. By sending specially crafted mrulist query packets, a physical attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 3.8
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119092> 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:H)
CVEID: CVE-2016-9310
Description: NTP is vulnerable to a denial of service, caused by an error in the control mode (mode 6) functionality. By sending specially crafted control mode packets, a remote attacker could exploit this vulnerability to obtain sensitive information and cause the application to crash.
CVSS Base Score: 6.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119087> 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:L)
CVEID: CVE-2016-9311
Description: NTP is vulnerable to a denial of service, caused by a NULL pointer dereference when trap service has been enabled. By sending specially crafted packets, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 4.4
