CVE-2024-41867
📋 TL;DR
CVE-2024-41867 is an out-of-bounds read vulnerability in Adobe After Effects that could allow an attacker to read sensitive memory contents. This could potentially bypass security mitigations like ASLR. Users of affected After Effects versions who open malicious project files are at risk.
💻 Affected Systems
- Adobe After Effects
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Memory disclosure leading to ASLR bypass enabling more sophisticated attacks, potentially allowing arbitrary code execution in combination with other vulnerabilities.
Likely Case
Information disclosure of memory contents, potentially revealing sensitive data or system information that could aid further attacks.
If Mitigated
Limited impact if user doesn't open untrusted files, with memory disclosure contained to the application's process space.
🎯 Exploit Status
Requires user to open malicious project file. Memory disclosure could be used to bypass ASLR for more reliable exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: After Effects 24.6 and later
Vendor Advisory: https://helpx.adobe.com/security/products/after_effects/apsb24-55.html
Restart Required: Yes
Instructions:
1. Open Adobe Creative Cloud application. 2. Navigate to 'Apps' section. 3. Find After Effects and click 'Update'. 4. Restart After Effects after update completes.
🔧 Temporary Workarounds
Restrict file opening
allOnly open project files from trusted sources and avoid opening unexpected files.
Application sandboxing
allRun After Effects in restricted/sandboxed environment to limit impact of memory disclosure.
🧯 If You Can't Patch
- Implement strict file handling policies to prevent opening untrusted project files
- Use application control solutions to restrict After Effects execution to trusted directories only
