Overview
The CVE-2025-53076 vulnerability is a critical flaw that has been identified in Samsung’s Open Source software rLottie version 0.2. This vulnerability arises from improper input validation which allows for buffer overreads, leading to potential system compromises or data leakage. As rLottie is a widely used library for rendering animations, this vulnerability has the potential to affect a large number of applications and platforms, making it a significant concern for cybersecurity professionals.

How the Exploit Works
The CVE-2025-53076 vulnerability is caused by insufficient input validation in rLottie. This allows an attacker to trigger a buffer overread by sending specially crafted data to the vulnerable application. Due to the overread, attacker-controlled data can be read by the application, potentially leading to information disclosure or, in some cases, remote code execution.
Conceptual Example Code
The following pseudocode demonstrates conceptually how the vulnerability might be exploited.
#include <stdio.h>
#include <string.h>
void vulnerable_function(char *input) {
char buffer[256];
strcpy(buffer, input); // Overread happens here with long input
printf("%s\n", buffer);
}
int main() {
char malicious_input[300];
memset(malicious_input, 'A', 299); // Fill with 'A'
malicious_input[299] = '\0'; // Null-terminate
vulnerable_function(malicious_input);
return 0;
}In this example, the malicious_input string is longer than the buffer in the vulnerable_function, causing a buffer overread when the input is copied into the buffer.
Mitigation Guidance
The primary mitigation for this vulnerability is to apply the vendor patch once it’s available. Until then, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can offer temporary mitigation by filtering out malicious input that could exploit this vulnerability. Additionally, implementing proper input validation and secure coding practices can reduce the risk of this and similar vulnerabilities.
