CVE-2025-27195
📋 TL;DR
CVE-2025-27195 is a heap-based buffer overflow vulnerability in Adobe Media Encoder that could allow arbitrary code execution when a user opens a malicious file. This affects users of Media Encoder versions 25.1, 24.6.4 and earlier. Successful exploitation requires user interaction but could lead to full system compromise under the current user's privileges.
💻 Affected Systems
- Adobe Media Encoder
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining the same privileges as the logged-in user, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Malicious actor tricks user into opening a specially crafted media file, leading to malware installation or data exfiltration from the affected system.
If Mitigated
With proper security controls, the impact is limited to the local user account on the affected system, with no privilege escalation or network propagation.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and knowledge of heap manipulation techniques. No public exploits have been reported as of the advisory date.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 25.2 and later versions
Vendor Advisory: https://helpx.adobe.com/security/products/media-encoder/apsb25-24.html
Restart Required: Yes
Instructions:
1. Open Adobe Creative Cloud application. 2. Navigate to the 'Apps' section. 3. Find Media Encoder and click 'Update'. 4. Follow the update prompts. 5. Restart the application after installation completes.
🔧 Temporary Workarounds
Restrict file opening
allConfigure application to only open trusted media files from known sources
Application control
allUse application whitelisting to prevent execution of unauthorized code
🧯 If You Can't Patch
- Implement strict user training about opening untrusted media files
- Deploy endpoint detection and response (EDR) solutions to monitor for suspicious process behavior
