Description
This security bulletin contains information about 4 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2016-7427)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The broadcast mode replay prevention functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via a crafted broadcast mode packet.
2) Resource exhaustion (CVE-ID: CVE-2016-7428)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via the poll interval in a broadcast packet.
3) Improper access control (CVE-ID: CVE-2016-9310)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information and cause DoS condition on the target system.
The weakness exists in the control mode (mode 6) functionality in ntpd due to improper access control. A remote attacker can set or unset traps via a specially crafted control mode packet, gain access to potentially sensitive information and cause the service to crash.
4) NULL pointer dereference (CVE-ID: CVE-2016-9311)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in ntpd due to NULL pointer dereference when the trap service is enabled. A remote attacker can submit a specially crafted packet and cause the service to crash.
