[+] References : https://packetstorm.news/files/id/213065/ & CVE-2025-64784
[+] Summary : A memory safety vulnerability exists in Adobe DNG SDK versions prior to v1.7.1.2410, affecting the Linearize() image processing routine.
When handling trimmed source images, the function erroneously performs operations using full image dimensions, resulting in an outāofābounds (OOB) read condition.
This proofāofāconcept demonstrates that, under controlled heap conditions, the OOB read can be reliably leveraged as a heap grooming primitive, enabling manipulation of adjacent heap objects.
By carefully influencing heap layout, the vulnerability may be escalated from a memory disclosure or denialāofāservice condition into potential arbitrary code execution through corrupted virtual dispatch structures.
The issue is tracked as CVE-2025-64784 and affects applications that statically or dynamically link vulnerable versions of the Adobe DNG SDK.
[+] Component: Image Linearization / Trimming Logic
[+] Function: Linearize()
[+] Root Cause: Use of full image bounds instead of active (trimmed) area dimensions
[+] Affected Versions :
Adobe DNG SDK prior to v1.7.1.2410
Any downstream software embedding or linking against affected SDK builds
[+] Vulnerability Class :
OutāofāBounds Read
Heap Memory Safety Violation
Potential Information Disclosure
Possible Code Execution (contextādependent)
[+] Technical Details
When a DNG image contains a trimmed active area, the SDK internally tracks reduced image bounds. However, the Linearize() routine incorrectly references the original fullāimage dimensions, causing memory reads beyond the allocated buffer.
While the primitive is inherently a readāonly violation, repeated invocations combined with predictable allocator behavior allow attackers to:
Shape heap layout (heap grooming)
Observe memory patterns and object placement
Influence object adjacency and virtual table resolution
In favorable conditions, this can lead to virtual function pointer reuse or redirection, transforming a theoretical OOB read into a practical exploitation vector.
[+] Impact :
Confidentiality: Medium ā possible heap memory disclosure
Integrity: Low to Medium ā indirect influence on control flow
Availability: High ā application crash or denial of service
On hardened systems, impact may be limited to crashes. On less protected builds, further escalation cannot be ruled out.
[+] Attack Vector :
Processing of a crafted DNG image file
Triggered via:
Image preview
Validation
Import or batch processing
Delivery may be local or remote, depending on the consuming application
[+] Mitigations :
Upgrade to Adobe DNG SDK v1.7.1.2410 or later
Ensure Linearize() enforces active area bounds
Validate image metadata before processing
Enable memoryāhardening mitigations:
ASLR
DEP / NX
Stack canaries
Fortify Source
Use sanitizers (ASan / UBSan) during testing
[+] Detection :
Crashes during DNG parsing or linearization
AddressSanitizer / Valgrind reports indicating OOB reads
Abnormal heap access patterns during image processing
[+] Proof of Concept (PoC)
The provided proofāofāconcept demonstrates controlled heap manipulation by:
Spraying heap allocations with deterministic patterns
Creating strategic free gaps to influence allocator behavior
Positioning crafted objects adjacent to vulnerable allocations
Leveraging the OOB read to interact with attackerācontrolled memory layouts
The PoC confirms that the vulnerability is exploitable beyond a simple crash, depending on runtime conditions and platform mitigations.
[+] POC :
5. How to Use:
bash
# 1. Prepare the environment
`chmod +x run_final_exploit.sh`
# 2. Run the full exploit
`./run_final_exploit.sh`
# 3. If it fails, try different versions
export HEAP_SPRAY_COUNT=500
export HEAP_SPRAY_SIZE=16384
./run_final_exploit.sh`
# 4. Or try a different libc version
./final_exploit exploit.dng final_exploit.dng 1 # Ubuntu 20.04
