CVE-2025-43580: Adobe Audition DOS Vulnerability

CVE-2025-43580 Overview

CVE-2025-43580 affects Adobe Audition versions 25.2, 24.6.3, and earlier. The vulnerability is classified as Access of Memory Location After End of Buffer [CWE-788], an out-of-bounds read condition. Successful exploitation results in application denial-of-service, causing Adobe Audition to crash or lose functionality. Exploitation requires user interaction: a victim must open a malicious file crafted by the attacker. The flaw is local in scope and does not compromise confidentiality or integrity, but does impact availability. Adobe published security advisory APSB25-56 addressing this issue.

Critical Impact
An attacker who convinces a user to open a malicious audio project file can crash Adobe Audition and disrupt digital audio production workflows on affected Windows and macOS systems.

Affected Products

Adobe Audition version 25.2 and earlier
Adobe Audition version 24.6.3 and earlier
Microsoft Windows and Apple macOS installations of the affected versions

Technical Details for CVE-2025-43580

Vulnerability Analysis

Adobe Audition contains an out-of-bounds read defect in its file parsing logic. When Audition processes a malformed input file, the application reads memory beyond the allocated buffer boundary. The read operation dereferences memory the process does not own or that contains unexpected content. The result is an unhandled exception that terminates the process. Because the impact is limited to availability, the vulnerability does not grant code execution or data disclosure. However, disruption of the application interrupts active editing sessions and can cause loss of unsaved work.

Root Cause

The defect maps to [CWE-788]: Access of Memory Location After End of Buffer. The parser fails to validate the size or bounds of a structure within a media file before reading from a computed offset. When crafted values in the file header or embedded chunks push read operations past the buffer, the process accesses memory outside the intended region.

Attack Vector

Exploitation requires local access and user interaction. The attacker delivers a malicious audio project or media file through email, download, or removable media. When the user opens the file in Adobe Audition, the parser triggers the out-of-bounds read and the application crashes. No network access, elevated privileges, or authentication bypass is involved. Refer to the Adobe Audition Security Advisory APSB25-56 for vendor technical details.

Detection Methods for CVE-2025-43580

Indicators of Compromise

Unexpected termination of the Adobe Audition.exe (Windows) or Adobe Audition (macOS) process shortly after opening a media file
Windows Application Event Log entries showing faulting module crashes originating from Audition
macOS CrashReporter diagnostic reports referencing Adobe Audition with EXC_BAD_ACCESS signals
Presence of unsolicited audio project files (.sesx, .wav, .mp3, and related formats) from untrusted sources

Detection Strategies

Monitor endpoint telemetry for repeated Adobe Audition process crashes correlated with file-open events
Alert on delivery of audio project files from external email senders to users with Adobe Audition installed
Track installed Adobe Audition versions across the fleet and flag hosts still running 25.2, 24.6.3, or earlier

Monitoring Recommendations

Ingest Windows Event Log IDs 1000 and 1001 and macOS crash reports into your SIEM for Audition-related faults
Baseline normal Audition file-handling activity so anomalous crashes are visible
Correlate file downloads and email attachments containing audio formats with subsequent Audition process termination

How to Mitigate CVE-2025-43580

Immediate Actions Required

Apply the patched Adobe Audition release identified in Adobe Security Advisory APSB25-56
Inventory all workstations running Adobe Audition and prioritize systems used by media production teams
Instruct users to avoid opening audio or project files received from untrusted or unverified sources

Patch Information

Adobe addressed the vulnerability in the security update documented in advisory APSB25-56. Administrators should update Adobe Audition to the fixed version published by Adobe. Use the Adobe Creative Cloud desktop application to deploy the update, or push the update through enterprise software distribution tooling.

Workarounds

Restrict Adobe Audition to opening files from vetted internal storage locations only
Use email gateway rules to strip or quarantine audio project attachments from external senders until patching is complete
Enforce least-privilege user accounts so a crashed application cannot be leveraged as a pivot for further disruption
