CVE-2024-41200 is a vulnerability identified in KMPlayer version 4.2.2.65, a popular multimedia player software. The issue arises from a segmentation fault triggered when the player processes a specially crafted AVI file. This memory corruption flaw leads to an application crash, resulting in a denial of service (DoS) condition. The vulnerability does not allow for code execution or data leakage, as it solely impacts the availability of the application. Exploitation requires the victim to open a malicious AVI file, implying user interaction is necessary. The attack vector is local (AV:L), meaning the attacker must have the ability to deliver the crafted file to the user’s environment. The CVSS v3.1 base score is 5.5 (medium severity), reflecting the limited scope and impact. No patches or fixes have been released at the time of publication, and no active exploits have been reported in the wild. The vulnerability could be leveraged by attackers to disrupt media playback services or cause inconvenience to end users. Given KMPlayer’s user base, the threat is primarily relevant to individual users and organizations that utilize this software for media consumption.

The primary impact of CVE-2024-41200 is denial of service, causing KMPlayer to crash when processing malicious AVI files. This disrupts media playback and can degrade user experience or operational continuity in environments relying on KMPlayer. Since the vulnerability does not affect confidentiality or integrity, there is no risk of data theft or unauthorized modification. However, repeated crashes could lead to productivity loss or user frustration. In enterprise environments where KMPlayer is used for training, presentations, or media processing, this could interrupt workflows. The requirement for user interaction and local file delivery limits large-scale automated exploitation, reducing the overall risk. No known exploits in the wild further mitigate immediate threat levels, but the absence of patches means the vulnerability remains open to potential future attacks.

1. Avoid opening AVI files from untrusted or unknown sources to prevent triggering the vulnerability. 2. Temporarily discontinue use of KMPlayer v4.2.2.65 until an official patch or update is released. 3. Employ application whitelisting or sandboxing to restrict KMPlayer’s access to untrusted files. 4. Monitor systems for unexpected KMPlayer crashes or abnormal behavior indicative of exploitation attempts. 5. Educate users about the risks of opening suspicious media files and encourage cautious handling of email attachments or downloads. 6. Consider deploying alternative, more secure media players with active maintenance and patching. 7. Once available, promptly apply vendor patches or updates addressing this vulnerability. 8. Implement endpoint detection and response (EDR) solutions to detect anomalous application crashes or exploitation attempts related to media files.
