Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The dissect_r3_upstreamcommand_queryconfig function in epan/dissectors/packet-assa_r3.c in the Assa Abloy R3 dissector in Wireshark 1.8.x before 1.8.8 does not properly handle a zero-length item, which allows remote attackers to cause a denial of service (infinite loop, and CPU and memory consumption) via a crafted packet.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Assa Abloy R3 dissector in Wireshark 1.8.x before 1.8.8 contains a vulnerability in the dissect_r3_upstreamcommand_queryconfig function where it fails to properly handle zero-length items in crafted packets, causing an infinite loop that leads to excessive CPU and memory consumption (denial of service).

MitigationUpgrade Wireshark to version 1.8.8 or later. Until then, avoid opening untrusted packet capture files and consider disabling the Assa Abloy R3 dissector if not required.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Wireshark version
    Run 'wireshark --version' or 'tshark --version' from command line to determine the exact version number
    Affected if Version is 1.8.0, 1.8.1, 1.8.2, 1.8.3, 1.8.4, 1.8.5, 1.8.6, or 1.8.7
  2. Confirm Wireshark is actively used
    Verify that Wireshark or TShark is installed and runnable on the system using 'which wireshark' or 'which tshark'
    Affected if Wireshark executables are found on the system in these vulnerable versions
  3. Determine if Assa Abloy R3 dissector is available
    Check dissector availability via Wireshark GUI under Analyze > Enabled Protocols, or inspect the compiled-in dissectors list
    Affected if The Assa Abloy R3 dissector (packet-r3.c) is compiled and enabled in this Wireshark installation

Environment is affected if Wireshark version 1.8.0 through 1.8.7 is installed with the Assa Abloy R3 dissector enabled, and a crafted packet file is opened or processed.

Mitigation

Upgrade Wireshark to version 1.8.8 or later. Until then, avoid opening untrusted packet capture files and consider disabling the Assa Abloy R3 dissector if not required.
