Description
This security bulletin contains information about 1 vulnerability.
1) Input validation error (CVE-ID: CVE-2016-9372)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/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 non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.2.0 to 2.2.1, the Profinet I/O dissector could loop excessively, triggered by network traffic or a capture file. This was addressed in plugins/profinet/packet-pn-rtc-one.c by rejecting input with too many I/O objects.
Remediation
Install update from vendor's website.
