CVE-2021-36003: Adobe Audition MP4 File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability

Adobe Audition version 14.2 (and earlier) is affected by an out-of-bounds read vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to disclose arbitrary memory information in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Security readout for executives and security teams

Plain-English summary

Adobe Audition 14.2 and earlier can leak memory when a user opens a maliciously crafted MP4 file. This is not a remote takeover issue, but it can expose sensitive data available to the current user process. Business risk is highest where staff routinely receive media files from outside parties.

Executive priority

Treat as a targeted workstation exposure, not an enterprise-wide emergency. Prioritize creative teams and users handling outside media, then close the version gap through normal endpoint patch management.

Technical view

CVE-2021-36003 is a CWE-125 out-of-bounds read in Adobe Audition MP4 parsing. CVSS 3.1 is 5.5, with local attack vector, no privileges required, required user interaction, unchanged scope, high confidentiality impact, and no integrity or availability impact.

Likely exposure

Exposure is likely limited to endpoints running Adobe Audition 14.2 or earlier, especially creative, audio, or marketing workstations that open externally supplied MP4 files.

Exploitation context

The bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires the victim to open a malicious file, so phishing, file-sharing, or supplier media workflows are the likely delivery paths.

Researcher notes

Evidence supports information disclosure through an out-of-bounds read during MP4 parsing. The source bundle does not provide exploit details, observed exploitation, or exact fixed build information, so remediation should track Adobe APSB21-62 rather than inferred version claims.

Mitigation direction

  • Inventory Adobe Audition installations and identify versions 14.2 or earlier.
  • Apply Adobe guidance from APSB21-62 or move to a supported fixed release.
  • Restrict opening unsolicited MP4 files on vulnerable Audition workstations.
  • Use endpoint controls to quarantine suspicious media attachments and downloads.

Validation and detection

  • Confirm installed Adobe Audition versions across managed endpoints.
  • Verify vulnerable versions have been updated or removed.
  • Review email and file-transfer workflows for unsolicited MP4 exposure.
  • Check endpoint alerts for suspicious media files opened by Audition.

Out-of-bounds Read

Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
