Overview
The cybersecurity landscape is ever-evolving, with new vulnerabilities being discovered on a frequent basis. One such vulnerability is the CVE-2025-53085, a memory corruption vulnerability, which exists in the SAIL Image Decoding Library v0.9.8. This vulnerability is significant as it impacts the PSD RLE Decoding functionality which is widely used for image data decompression. This vulnerability can lead to a heap-based buffer overflow, enabling remote code execution. The severity of this vulnerability lies in its potential for system compromise and data leakage, making it a critical concern for any organization or individual using this version of the library.

Product | Affected Versions
SAIL Image Decoding Library | v0.9.8
How the Exploit Works
The vulnerability arises from a flaw in the PSD RLE Decoding functionality of the SAIL Image Decoding Library. When a specially crafted .psd file is decompressed, it can cause a heap-based buffer overflow. This overflow, in turn, allows for remote code execution. An attacker would need to convince the library to read this malicious .psd file to trigger the vulnerability, potentially leading to system compromise and data leakage.
Conceptual Example Code
The following pseudocode gives a conceptual idea of how the vulnerability might be exploited. It involves the process of decompressing a malicious .psd file which triggers the heap-based buffer overflow and leads to remote code execution.
# Pseudocode
def trigger_vulnerability(file):
library = load_library('SAIL Image Decoding Library v0.9.8')
psd_file = open(file, 'rb')
image_data = library.decompress(psd_file)
execute_remote_code(image_data)
trigger_vulnerability('malicious.psd')This pseudocode represents the process an attacker might follow to exploit the vulnerability. The ‘malicious.psd’ file would be a specially crafted .psd file that causes a heap-based buffer overflow when decompressed using the vulnerable version of the SAIL Image Decoding Library.
