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
In SWFTools, an address access exception was found in swfdump swf_GetBits().

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 · moderate confidence

A memory access violation exists in SWFTools' swfdump utility within the swf_GetBits() function. This appears to be an out-of-bounds or invalid address access when parsing SWF files, potentially allowing crafted input to trigger the exception.

MitigationUpgrade to a patched version of SWFTools that addresses the address access issue in swf_GetBits(). If no patched version exists, avoid processing untrusted SWF files with swfdump.

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. Verify swfdump utility is present
    Check if the swfdump binary exists on the system by running 'which swfdump' or 'command -v swfdump'
    Affected if The swfdump binary is found on the system
  2. Confirm the binary belongs to SWFTools
    Run 'swfdump --version' or 'swfdump -h' and verify the output identifies the tool as part of the SWFTools package
    Affected if The binary is identified as swfdump from SWFTools
  3. Identify if swfdump processes untrusted SWF files
    Review any scripts, pipelines, or automated processes that invoke swfdump to parse SWF input, or check user directories for recent swfdump usage
    Affected if swfdump is used to parse SWF files from untrusted or external sources
  4. Assess exposure level
    Determine whether swfdump is accessible to untrusted users or exposed via web-facing services that process SWF uploads
    Affected if Untrusted users can trigger swfdump to process arbitrary SWF files

If swfdump from SWFTools is installed and is used to parse SWF files, the environment is affected since all versions of Swftools contain this vulnerability in the swf_GetBits() function.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to a patched version of SWFTools that addresses the address access issue in swf_GetBits(). If no patched version exists, avoid processing untrusted SWF files with swfdump.
