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-2016-7433 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-2016-9310 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 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/119086 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H) 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.
