Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU14423

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-5209

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information.

The vulnerability exists due to an error when handling malicious input. A remote attacker can send a specially crafted GET_RESTRICT control message and gain access to internal or alternative IP addresses and other sensitive information.

Mitigation

Install update from vendor's website.

Vulnerable software versions

IBM AIX: 5.3 - 7.2

CPE2.3 External links

http://aix.software.ibm.com/aix/efixes/security/ntp_advisory10.asc


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Information disclosure

EUVDB-ID: #VU10798

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2018-7182

CWE-ID: CWE-200 - Information exposure

Exploit availability: Yes

Description

The vulnerability allows a remote unautheticated attacker to obtain potentially sensitive information.

The weakness exists due to insufficient validation user-supplied input. A remote attacker can submit a specially crafted mode 6 packet and gain access to potentially sensitive information.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.

3) Memory corruption

EUVDB-ID: #VU10802

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-7183

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.

The weakness exists in the decodearr() function of the ntpq monitoring and control program for ntpd used by the Network Time Protocol due to boundary error while attempting to decode an array in a response string when formatted data is being displayed. A remote attacker who is able to read an ntpq request while the request is being transmitted to a remote ntpd server can forge and send a specially crafted response to the targeted system prior to the remote ntpd server sending its response, trigger out-of-bounds write in the decodearr() function and  inject and execute arbitrary code.

Mitigation

Install update from vendor's website.
