    Samsung Open Source rLottie | V0.2

    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.
