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_atn_cpdlc_heur function in asn1/atn-cpdlc/packet-atn-cpdlc-template.c in the ATN-CPDLC dissector in Wireshark 1.12.x before 1.12.4 does not properly follow the TRY/ENDTRY code requirements, which allows remote attackers to cause a denial of service (stack memory corruption and application crash) 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

Wireshark's ATN-CPDLC dissector has a stack memory corruption vulnerability in the dissect_atn_cpdlc_heur function. The function fails to properly implement TRY/ENDTRY exception handling code requirements, leading to stack corruption when parsing specially crafted CPDLC packets, resulting in application crash.

MitigationUpdate Wireshark to version 1.12.4 or later. Alternatively, disable the ATN-CPDLC dissector or avoid opening packet captures from untrusted sources until the update is applied.

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 see the exact version number
    Affected if Version is 1.12.0, 1.12.1, 1.12.2, or 1.12.3
  2. Confirm Wireshark package version on OpenSUSE
    Run 'rpm -qa | grep wireshark' or check package manager for wireshark package version
    Affected if Package version corresponds to Wireshark 1.12.0 through 1.12.3
  3. Verify ATN-CPDLC dissector is loaded
    In Wireshark GUI, go to Analyze > Enabled Protocols and search for 'ATN-CPDLC' or 'atn-cpdlc', or run 'tshark -G protocols' to list available dissectors
    Affected if ATN-CPDLC protocol is enabled (not disabled) in the protocol settings

You are affected if you have Wireshark version 1.12.0 through 1.12.3 installed AND the ATN-CPDLC dissector is enabled, and you parse CPDLC traffic from untrusted capture files.
