Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly mitigates the vulnerability by requiring timely remediation through patching the known integer overflow and heap buffer overflow in SAIL library's PSD decoding.

prevent

Implements memory safeguards like address space layout randomization and data execution prevention to block remote code execution from the heap buffer overflow.

prevent

Validates image file inputs to detect and reject specially crafted PSD files that trigger the integer overflow during stride calculation.

MITRE ATT&CK Enterprise TechniquesAI

T1203 Exploitation for Client Execution Execution
Adversaries may exploit software vulnerabilities in client applications to execute code.
T1204.002 Malicious File Execution
An adversary may rely upon a user opening a malicious file in order to gain execution.
Why these techniques?

Malicious PSD file triggers client-side buffer overflow for RCE (T1203 Exploitation for Client Execution); requires user to open the file (T1204.002 Malicious File).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

A memory corruption vulnerability exists in the PSD Image Decoding functionality of the SAIL Image Decoding Library v0.9.8. When loading a specially crafted .psd file, an integer overflow can be made to occur when calculating the stride for decoding. Afterwards,…

this will cause a heap-based buffer to overflow when decoding the image which can lead to remote code execution. An attacker will need to convince the library to read a file to trigger this vulnerability.

Deeper analysisAI

CVE-2025-53510 is a memory corruption vulnerability in the PSD Image Decoding functionality of the SAIL Image Decoding Library version 0.9.8. The issue arises when loading a specially crafted .psd file, triggering an integer overflow during stride calculation for decoding. This overflow subsequently causes a heap-based buffer overflow during image decoding, potentially leading to remote code execution. The vulnerability is classified under CWE-680 with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

An attacker can exploit this vulnerability by crafting a malicious .psd file and convincing a user or application to load it via the affected library, as no privileges are required and exploitation occurs over a network with low complexity. User interaction is necessary, such as opening the file in a supporting image viewer or editor. Successful exploitation grants high confidentiality, integrity, and availability impacts, enabling remote code execution in the context of the application using the library.

The primary advisory is documented in the Talos Intelligence report TALOS-2025-2218, available at https://talosintelligence.com/vulnerability_reports/TALOS-2025-2218. Specific mitigation details, such as patches or workarounds, are outlined in this reference.
