Security readout for executives and security teams
Plain-English summary
CVE-2020-9745 affects Adobe Media Encoder 14.3.2 and earlier. A crafted PSD-related file or page could cause the application to read beyond intended memory, potentially crashing or exposing sensitive memory contents. The risk is moderated by required user interaction.
Executive priority
Treat as a moderate workstation risk. Prioritize remediation on systems handling external creative files, because compromise depends on user interaction but could expose sensitive memory or disrupt production workflows.
Technical view
This is a CWE-125 out-of-bounds read in Adobe Media Encoder PSD file parsing. CVSS 3.1 is 6.1, with local attack vector, no privileges required, user interaction required, high confidentiality impact, no integrity impact, and low availability impact.
Likely exposure
Exposure is most likely where Adobe Media Encoder 14.3.2 or earlier is installed and users process PSD or other untrusted media content. Creative, marketing, media production, and post-production workstations are the most relevant assets.
Exploitation context
The provided sources say exploitation requires the target to visit a malicious page or open a malicious file. The source bundle does not show CISA KEV listing or any other cited evidence of active exploitation.
Researcher notes
The evidence supports a PSD parsing out-of-bounds read, not code execution. Validate exposure through version inventory and vendor bulletin comparison. Do not assume broader Adobe product impact or exploit availability beyond the supplied sources.
Mitigation direction
- Review Adobe APSB20-57 for the vendor-designated fixed version.
- Upgrade or remove Adobe Media Encoder 14.3.2 and earlier where present.
- Avoid opening untrusted PSD or media files in vulnerable installations.
- Use email, web, and endpoint controls to block suspicious creative-file delivery.
Validation and detection
- Inventory endpoints for Adobe Media Encoder installations and versions.
- Flag installations at version 14.3.2 or earlier for remediation.
- Confirm the Adobe APSB20-57 update has been applied where applicable.
- Review security telemetry for crashes after opening unexpected PSD or media files.

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.
