Security readout for executives and security teams
Plain-English summary
Adobe Audition had a low-severity MP4 parsing flaw. A malicious MP4 opened by a user could cause Audition to read memory it should not, potentially exposing sensitive process memory and helping bypass protections such as ASLR.
Executive priority
Treat as routine desktop patching, with faster handling for media production or security-sensitive teams that open externally supplied MP4 files. Business risk is limited but credible because memory disclosure can support chained attacks.
Technical view
CVE-2021-44699 is a CWE-125 out-of-bounds read in Adobe Audition 14.4 and earlier, and 22.0 and earlier. The CVSS 3.1 score is 3.3 with local attack vector, required user interaction, low confidentiality impact, and no integrity or availability impact.
Likely exposure
Exposure is mainly desktop systems with affected Adobe Audition versions, especially users who receive or process MP4 files from clients, public submissions, or other untrusted sources.
Exploitation context
The provided sources do not indicate active exploitation or CISA KEV listing. Exploitation requires user interaction: the victim must open a malicious MP4 file in an affected Audition version.
Researcher notes
The public bundle supports an out-of-bounds read leading to sensitive memory disclosure and possible ASLR bypass. No exploit code, active exploitation, or detailed fixed-version mapping is included in the supplied evidence.
Mitigation direction
- Apply Adobe Audition updates referenced by Adobe APSB21-121.
- Prioritize users who handle externally supplied MP4 files.
- Avoid opening unsolicited or untrusted MP4 files in vulnerable Audition versions.
- Check Adobe guidance for exact fixed versions and deployment instructions.
Validation and detection
- Inventory Adobe Audition installations and versions across managed endpoints.
- Identify systems running Audition 14.4 or earlier, or 22.0 or earlier.
- Confirm updates align with Adobe APSB21-121 guidance.
- Review media intake workflows for untrusted MP4 handling.

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.
