CVE-2024-53954 Overview
CVE-2024-53954 is an integer underflow vulnerability [CWE-191] affecting Adobe Animate versions 23.0.8, 24.0.5, and earlier. The flaw allows arbitrary code execution in the context of the current user when a victim opens a crafted file. Exploitation requires user interaction, which limits remote attack scenarios but remains practical through phishing and social engineering.
Adobe disclosed the issue in security bulletin APSB24-96. The vulnerability affects installations on both Microsoft Windows and Apple macOS platforms. No public proof-of-concept exists, and the flaw is not listed in the CISA Known Exploited Vulnerabilities catalog.
Critical Impact
Successful exploitation grants attackers arbitrary code execution with the privileges of the logged-in user, enabling malware installation, data theft, or lateral movement.
Affected Products
- Adobe Animate 23.0.8 and earlier (version 23.x)
- Adobe Animate 24.0.5 and earlier (version 24.x)
- Deployments on Microsoft Windows and Apple macOS

Technical Details for CVE-2024-53954
Vulnerability Analysis
CVE-2024-53954 is classified as an Integer Underflow (Wrap or Wraparound) [CWE-191]. The defect occurs when arithmetic operations on unsigned integers produce values below zero, wrapping to very large positive numbers. When these wrapped values are used as buffer sizes or offsets, subsequent memory operations write outside intended bounds.
The underflow condition is reached during parsing of a malicious Animate project or asset file. Attackers craft file structures containing length fields or size descriptors that trigger the arithmetic error during deserialization. Corrupted memory management then permits attacker-controlled data to overwrite adjacent structures, including function pointers or return addresses.
Exploitation runs code in the security context of the user executing Adobe Animate. On systems where designers operate with administrative privileges, the impact expands to full system compromise. The attack vector is local, requiring the victim to open the malicious file.
Root Cause
The root cause is missing validation of size or length values before arithmetic operations in Adobe Animate's file parsing logic. When a specially constructed input causes a subtraction to underflow, the resulting large value bypasses length checks. Adobe has not published detailed technical analysis of the affected component.
Attack Vector
An attacker delivers a crafted Animate file through email, malicious websites, or shared storage. Opening the file in a vulnerable version of Animate triggers the underflow during parsing. Code execution occurs before the user sees any visible content.
See Adobe Security Bulletin APSB24-96 for advisory details. No verified proof-of-concept code is publicly available.
Detection Methods for CVE-2024-53954
Indicators of Compromise
- Adobe Animate processes (Animate.exe, Adobe Animate) spawning child processes such as cmd.exe, powershell.exe, or shell interpreters
- Unexpected outbound network connections initiated by the Animate process shortly after a file is opened
- Creation of executable files or scripts in user-writable directories following Animate file activity
Detection Strategies
- Monitor endpoint telemetry for anomalous process creation chains originating from Adobe Animate
- Alert on Animate loading unexpected DLLs or accessing sensitive system APIs outside its normal behavior profile
- Inspect email gateways and file shares for Adobe Animate project files (.fla, .xfl, .as) from untrusted sources
Monitoring Recommendations
- Log Adobe Animate version telemetry across managed endpoints and flag hosts running versions at or below 23.0.8 and 24.0.5
- Correlate file-open events with subsequent process, file, and network activity to identify exploitation attempts
- Track user reports of Animate crashes, which may indicate failed exploitation of the underflow condition
How to Mitigate CVE-2024-53954
Immediate Actions Required
- Update Adobe Animate to the fixed versions identified in Adobe Security Bulletin APSB24-96
- Inventory all endpoints running Adobe Animate and prioritize patching for creative and design teams
- Instruct users to avoid opening Animate files from untrusted email attachments, download sites, or shared drives
Patch Information
Adobe released fixed builds of Animate addressing this integer underflow. Refer to Adobe Security Bulletin APSB24-96 for exact patched version numbers and download links. Apply updates through the Adobe Creative Cloud desktop application or enterprise deployment tooling.
Workarounds
- Restrict Adobe Animate to standard user accounts to limit the impact of successful exploitation
- Use application allowlisting to prevent Animate from spawning script interpreters or unauthorized executables
- Block inbound Animate file types at email gateways when they originate from external senders and are not business-required
# Example: Verify installed Adobe Animate version on Windows
reg query "HKLM\SOFTWARE\Adobe\Animate" /s | findstr /i "Version"
# Example: Verify installed Adobe Animate version on macOS
defaults read "/Applications/Adobe Animate 2024/Adobe Animate 2024.app/Contents/Info.plist" CFBundleShortVersionString
