Security readout for executives and security teams
Plain-English summary
CVE-2017-9347 is a denial-of-service flaw in Wireshark 2.2.0 through 2.2.6. A malformed ROS protocol item could make Wireshark crash while analyzing traffic or a capture file. The business impact is analyst/tool disruption, not documented data theft or system takeover.
Executive priority
Treat this as a bounded operational resilience issue. It can interrupt packet analysis workflows, but the provided evidence does not show remote code execution, data compromise, or active exploitation.
Technical view
The Wireshark ROS dissector could dereference a NULL pointer when processing an invalid OID. The source bundle says the issue was fixed in epan/dissectors/asn1/ros/packet-ros-template.c by validating the OID. No CVSS, CWE, or CPE detail is provided.
Likely exposure
Exposure is most likely on analyst workstations, security appliances, or lab systems running Wireshark 2.2.0 to 2.2.6 and opening untrusted captures or dissecting ROS-related traffic.
Exploitation context
The bundle includes an Exploit-DB reference, so public exploit material exists. KEV is false, and the provided sources do not establish active exploitation in the wild.
Researcher notes
Focus review on ROS dissector OID handling and crash reproduction boundaries. The available CVE data is sparse: no CVSS vector, CWE, or normalized affected CPEs are supplied.
Mitigation direction
- Upgrade affected Wireshark 2.2.0-2.2.6 installations using Wireshark vendor guidance.
- Avoid opening untrusted capture files on vulnerable Wireshark versions.
- Restrict vulnerable analysis systems from processing unsolicited or unknown traffic captures.
- Prioritize replacement of unsupported Wireshark builds on analyst workstations.
Validation and detection
- Inventory Wireshark versions and flag 2.2.0 through 2.2.6.
- Confirm the installed build includes the ROS OID validation fix.
- Review crash reports for Wireshark ROS dissector failures.
- Check whether teams process untrusted packet captures with affected versions.
