Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Resource exhaustion

EUVDB-ID: #VU39822

Risk: Low

CVSSv4.0: 1.3 [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]

CVE-ID: CVE-2016-7427

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.

2) Resource exhaustion

EUVDB-ID: #VU39823

Risk: Low

CVSSv4.0: 1.3 [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]

CVE-ID: CVE-2016-7428

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.

3) Improper access control

EUVDB-ID: #VU12305

Risk: Low

CVSSv4.0: 6.8 [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]

CVE-ID: CVE-2016-9310

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.

4) NULL pointer dereference

EUVDB-ID: #VU12306

Risk: Medium

CVSSv4.0: 6.6 [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]

CVE-ID: CVE-2016-9311

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.
