Security readout for executives and security teams

Plain-English summary

CVE-2018-9267 is a memory leak in Wireshark's LAPD dissector affecting Wireshark 2.4.0 through 2.4.5 and 2.2.0 through 2.2.13. The business risk is resource exhaustion during packet analysis, not data theft based on the provided sources.

Executive priority

Handle through normal vulnerability management unless affected Wireshark is used heavily for untrusted captures. Prioritize shared analysis platforms and security operations workstations because resource exhaustion can disrupt investigations.

Technical view

The issue is in epan/dissectors/packet-lapd.c and is described only as a memory leak. The provided bundle includes Wireshark advisory and commit references, but no CVSS score, CWE, exploit detail, or exact fixed-version statement.

Likely exposure

Exposure is most likely where affected Wireshark versions process LAPD traffic or packet captures. This mainly concerns analyst workstations, shared packet-analysis systems, and distributions shipping vulnerable Wireshark packages.

Exploitation context

CISA KEV is false, and the provided sources do not state active exploitation. The bundle does not provide exploit mechanics, so treat exploitation likelihood as unconfirmed and focus on version-based remediation.

Researcher notes

The available record is sparse: no CVSS, CWE, or exploit status is provided. Analysis should stay anchored to version exposure and the LAPD dissector memory-leak description until vendor advisory details are reviewed.

Mitigation direction

  • Identify Wireshark installs in versions 2.4.0-2.4.5 and 2.2.0-2.2.13.
  • Update Wireshark according to Wireshark or OS vendor guidance.
  • Apply relevant Debian LTS security updates where Debian-packaged Wireshark is used.
  • Avoid opening untrusted packet captures with affected Wireshark versions.
  • Monitor packet-analysis hosts for unusual memory growth until remediated.

Validation and detection

  • Confirm deployed Wireshark versions are outside the listed affected ranges.
  • Check package manager records for the applicable Wireshark security update.
  • Review analyst workstations and shared capture-processing systems for vulnerable versions.
  • Verify remediation against the Wireshark advisory and referenced commit.
  • Document any systems that cannot be updated and their compensating controls.
