Integer overflow in the dissect_osd2_cdb_continuation function in epan/dissectors/packet-scsi-osd.c in the SCSI OSD dissector in Wireshark 1.12.x before 1.12.4 allows remote attackers to cause a denial of service (infinite loop) via a crafted length field in a packet.

Analyst readout for executives and security teams

Plain-English summary

This flaw can make vulnerable Wireshark versions hang when they process a specially crafted packet. It affects analysis tooling, not the protected production service itself. Business urgency is mainly for teams that inspect untrusted traffic captures or monitor live traffic with Wireshark 1.12.x before 1.12.4.

Executive priority

Treat this as a moderate-priority tooling resilience issue. Patch affected security-analysis workstations and monitoring hosts, but do not escalate as a confirmed active breach risk based on the supplied evidence.

Technical view

CVE-2015-2192 is an integer overflow in Wireshark’s SCSI OSD dissector, specifically dissect_osd2_cdb_continuation in packet-scsi-osd.c. A crafted length field can trigger an infinite loop, causing denial of service. Sources identify Wireshark 1.12.x before 1.12.4 as affected.

Likely exposure

Exposure is likely limited to systems running vulnerable Wireshark builds, especially analyst workstations, packet-capture review hosts, and monitoring systems that parse untrusted or hostile network traffic.

Exploitation context

The CVE describes remote denial of service via a crafted packet length field. The provided sources do not show CISA KEV listing or confirmed active exploitation, so exploitation should be treated as plausible but not proven active.

Researcher notes

Focus validation on version evidence and parsing exposure. The core issue is an integer overflow leading to an infinite loop in the SCSI OSD dissector. Public sources identify the fix boundary but do not provide CVSS details in the bundle.

Mitigation direction

  • Upgrade Wireshark 1.12.x installations to 1.12.4 or later.
  • Apply distribution security updates from supported vendors such as openSUSE or Gentoo where applicable.
  • Check Wireshark vendor guidance for any environment-specific remediation notes.
  • Prioritize analyst and monitoring systems that inspect untrusted packet captures.

Validation and detection

  • Inventory Wireshark installations and confirm no 1.12.x build earlier than 1.12.4 remains.
  • Verify security update status through the relevant operating system package manager or vendor advisory.
  • Identify systems that process untrusted captures or live traffic with SCSI OSD dissector support.
  • Review recent Wireshark hangs or analysis workstation availability issues for possible correlation.
