CVE-2025-65404 identifies a buffer overflow vulnerability in the getSideInfo2() function of the Live555 Streaming Media library, specifically in version 2018.09.02. Live555 is widely used for streaming media applications, including RTSP, RTP, and RTCP protocols. The vulnerability arises when processing MP3 streams, where a crafted MP3 input can overflow a buffer in the getSideInfo2() function, which handles side information parsing in MP3 frames. This overflow can cause the application to crash, resulting in a Denial of Service (DoS). The vulnerability does not require any privileges (AV:N) and has low attack complexity (AC:L), but does require user interaction (UI:R) since the victim must process the malicious MP3 stream. The scope is unchanged (S:U), and the impact is limited to availability (A:H), with no impact on confidentiality or integrity. No patches or fixes have been released yet, and no known exploits are reported in the wild. The vulnerability is classified under CWE-120 (Classic Buffer Overflow), a common and well-understood flaw. Organizations using Live555 for media streaming or processing should be aware of this vulnerability as it can disrupt service availability and potentially impact user experience or service reliability.

For European organizations, the primary impact of CVE-2025-65404 is service disruption due to Denial of Service attacks. Media streaming providers, broadcasters, and any enterprises relying on Live555 for streaming infrastructure could face outages or degraded service quality if targeted. This could lead to loss of customer trust, revenue impact, and operational challenges. Since the vulnerability does not affect confidentiality or integrity, data breaches are unlikely. However, availability disruptions could affect critical communications, especially in sectors like media, telecommunications, and public services that rely on streaming technologies. The lack of known exploits reduces immediate risk, but the ease of exploitation and absence of patches necessitate proactive mitigation. European organizations with high dependency on streaming media should prioritize detection and containment to avoid service interruptions.

1. Restrict and validate all incoming MP3 streams from untrusted or external sources to prevent processing maliciously crafted inputs. 2. Implement network-level filtering or segmentation to isolate streaming media servers and reduce exposure. 3. Monitor application logs and system behavior for abnormal crashes or restarts indicative of exploitation attempts. 4. Employ runtime protections such as Address Space Layout Randomization (ASLR) and stack canaries to mitigate buffer overflow impacts. 5. Prepare for patch deployment by tracking Live555 updates and applying fixes promptly once available. 6. Consider using alternative or updated media streaming libraries that have addressed this vulnerability. 7. Educate users and administrators about the risk of processing untrusted media streams and enforce strict content ingestion policies. 8. Conduct regular security assessments and penetration testing focused on media processing components.
