CVE-2025-0634 is a Use After Free (CWE-416) vulnerability identified in Samsung's open source rLottie library version 0.2, which is used for rendering vector animations in various applications and devices. The vulnerability arises from improper handling of memory, where a previously freed memory region is accessed, potentially allowing an attacker to manipulate program execution flow. This flaw can be exploited remotely without requiring authentication, but it does require user interaction, such as opening a maliciously crafted animation file or content that uses rLottie. Successful exploitation could lead to remote code inclusion, enabling attackers to execute arbitrary code on the affected system, compromising confidentiality, integrity, and availability. The CVSS 4.0 score of 5.1 reflects a medium severity level, with network attack vector, low complexity, and no privileges required. Although no public exploits have been reported yet, the vulnerability poses a significant risk to applications and devices embedding this library, especially those distributed by Samsung or third parties leveraging rLottie. The lack of a patch link suggests that a fix may still be pending or in development, emphasizing the need for vigilance and proactive mitigation. The vulnerability's impact is heightened by the widespread use of Samsung devices and software in consumer and enterprise environments, particularly in Europe where Samsung holds substantial market share.

For European organizations, this vulnerability could lead to unauthorized remote code execution on devices or applications using the vulnerable rLottie library, potentially resulting in data breaches, system compromise, or service disruption. Given the medium severity, the impact on confidentiality, integrity, and availability is moderate but non-negligible. Enterprises relying on Samsung devices or software that incorporate rLottie animations—such as smart TVs, mobile devices, or embedded systems—may face increased risk of targeted attacks exploiting this flaw. The requirement for user interaction means phishing or social engineering could be used to trigger the exploit. Critical sectors such as finance, healthcare, and government could be targeted due to the strategic value of Samsung devices in these environments. Additionally, the lack of an available patch increases exposure time, necessitating interim protective measures. The vulnerability could also affect software vendors and developers who integrate rLottie into their products, potentially expanding the attack surface across multiple industries.

1. Monitor Samsung and the rLottie project for official patches or updates addressing CVE-2025-0634 and apply them promptly once available. 2. Until a patch is released, restrict or disable the use of rLottie animations in applications and devices where feasible, especially in high-risk environments. 3. Implement strict input validation and sanitization to prevent processing of untrusted or malformed animation files that could trigger the vulnerability. 4. Employ application-level sandboxing and memory protection techniques such as Address Space Layout Randomization (ASLR) and Data Execution Prevention (DEP) to reduce exploitation success. 5. Educate users about the risks of opening unsolicited or suspicious animation content to reduce the likelihood of successful social engineering attacks. 6. Conduct thorough code audits and penetration testing on applications embedding rLottie to identify and remediate potential exploitation vectors. 7. Use network security controls to monitor and block suspicious traffic patterns that may indicate exploitation attempts. 8. Collaborate with vendors and third-party developers to ensure awareness and coordinated response to this vulnerability.
