WiresharkApplication
CVE-2015-8730
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 · uneditedepan/dissectors/packet-nbap.c in the NBAP dissector in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1 does not validate the number of items, which allows remote attackers to cause a denial of service (invalid read operation 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 confidenceThe NBAP dissector in Wireshark (packet-nbap.c) fails to validate item counts before reading packet data, allowing malformed packets to trigger out-of-bounds read operations and crash the application via denial of service.

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 checksWork through these to decide whether this CVE applies to you.
-
Determine your installed Wireshark versionRun 'wireshark --version' from command line, or open Wireshark and go to Help > About Wireshark to view the version numberAffected if The version is 1.12.0 through 1.12.8, or exactly 2.0.0 (these are the affected versions)
-
Verify the NBAP protocol dissector is availableOpen Wireshark, go to Analyze > Enabled Protocols, then search for 'nbap' in the protocol list to confirm the dissector is present and enabledAffected if The NBAP dissector is enabled and present in the protocol list
-
Identify if NBAP traffic is being processedOpen a packet capture file (pcap/pcapng) or observe live network traffic that may contain NBAP signaling (NBAP is used in 3G WCDMA networks)Affected if Processing packet captures or live traffic that contains NBAP protocol data from untrusted sources
-
Confirm the vulnerability trigger conditionThe flaw is triggered when malformed NBAP packets with invalid item counts are processed by the dissector, causing out-of-bounds reads and application crashAffected if A malformed packet with specifically crafted invalid item count values is processed by the NBAP dissector
You are affected if you are running Wireshark versions 1.12.0-1.12.8 or 2.0.0 and processing NBAP protocol traffic from untrusted or unknown sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to Wireshark 1.12.9+/2.0.1+ or later versions. Avoid opening untrusted packet capture files from untrusted sources.
