Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU33525

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-2017-11406

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

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

In Wireshark 2.2.0 to 2.2.7 and 2.0.0 to 2.0.13, the DOCSIS dissector could go into an infinite loop. This was addressed in plugins/docsis/packet-docsis.c by rejecting invalid Frame Control parameter values.

Mitigation

Install updates from vendor's repository.

2) Input validation error

EUVDB-ID: #VU33526

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-2017-11407

Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

In Wireshark 2.2.0 to 2.2.7 and 2.0.0 to 2.0.13, the MQ dissector could crash. This was addressed in epan/dissectors/packet-mq.c by validating the fragment length before a reassembly attempt.

Mitigation

Install updates from vendor's repository.
