Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU8072

Risk: Low

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-13767

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to infinite loop in the MSDP dissector. A remote attacker can inject a malformed packet onto the wire, trigger Wireshark to consume excessive CPU resources and cause the application to crash.

Successful exploitation of the vulnerability results in denial of service.

Mitigation

The vulnerability is addressed in the following versions: 2.0.15, 2.2.9 or 2.4.1.

Vulnerable software versions

Wireshark: 2.0.0 - 2.4.0

Q & A

Can this vulnerability be exploited remotely?

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

How the attacker can exploit this vulnerability?

The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.

Is there known malware, which exploits this vulnerability?

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

2) Out-of-bounds write

EUVDB-ID: #VU8073

Risk: Low

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-13766

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to out-of-bounds write in the Profinet I/O dissector. A remote attacker can inject a malformed packet onto the wire, trigger Wireshark to consume excessive CPU resources and cause the application to crash.

Successful exploitation of the vulnerability results in denial of service.

Mitigation

The vulnerability is addressed in the following versions: 2.2.9 or 2.4.1.

Vulnerable software versions

Wireshark: 2.2.0 - 2.4.0
