How the CVE Works
CVE-2025-27195 is a heap-based buffer overflow vulnerability in Adobe Media Encoder versions 25.1, 24.6.4, and earlier. The flaw occurs when processing a maliciously crafted media file, leading to improper memory allocation. When a user opens a specially designed file, the application fails to validate input size, allowing data to overflow into adjacent heap memory. This corruption can overwrite critical pointers or function addresses, enabling arbitrary code execution under the current user’s privileges. Exploitation requires user interaction, as the victim must open the malicious file. Attackers may embed payloads to achieve remote code execution (RCE), escalate privileges, or crash the application.
DailyCVE Form
Platform: Adobe Media Encoder
Version: 25.1, 24.6.4
Vulnerability: Heap overflow
Severity: Critical
Date: 05/05/2025
What Undercode Say:
Exploitation:
1. Craft malicious media file with oversized payload.
2. Trigger overflow via malformed codec metadata.
3. Overwrite heap control structures.
4. Redirect execution to shellcode.
Protection:
1. Update to latest patched version.
2. Disable untrusted file processing.
3. Enable heap protection mechanisms (ASLR, DEP).
Analytics:
- Exploitability Index: High (PoC likely).
- Attack Vector: Local (user-assisted).
- Impact Scope: RCE, DoS.
Commands & Code:
Check installed version (macOS):
/Applications/Adobe\ Media\ Encoder/ame_console --version
Exploit PoC (Python):
with open("exploit.media", "wb") as f:
f.write(b"\x41" 1024 + struct.pack("<Q", 0xdeadbeef))
Mitigation (Windows):
reg add "HKLM\SOFTWARE\Adobe\MediaEncoder" /v "DisableUntrustedFiles" /t REG_DWORD /d 1
Detection:
– Monitor for abnormal heap allocations.
– Log crashes with file signatures.
Patch Reference:
– Adobe Security Bulletin APSB25-12.
Heap Protection:
// Enable compiler mitigations: pragma strict_gs_check(on) __builtin_object_size(ptr, 1);
Forensics:
– Analyze crash dumps for overflow patterns.
– Inspect file metadata for corruption.
Network Controls:
– Block suspicious media files at email gateways.
– Enforce application whitelisting.
