FFmpeg git-master, specifically version N-113007-g8d24a28d06, was discovered to contain a segmentation violation through the component /libavcodec/jpeg2000dec.c. This vulnerability is classified as medium severity with a CVSS score of 6.5, indicating that while it poses a significant risk, it may not be as critical as high-severity vulnerabilities.
Risk to organizations includes potential denial of service due to high availability impact. The vulnerability requires user interaction to exploit, which may limit its immediate risk but does not eliminate the need for prompt remediation.
Currently, there are no known exploits in the wild for this vulnerability, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant as the situation could evolve.
Organizations should prioritize patching immediately to prevent any potential exploitation and maintain the integrity of their systems.
Vulnerability Details
The vulnerability is classified under CWE-476, indicating an issue related to NULL Pointer Dereference. The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H, highlighting a network attack vector with low complexity and no privileges required.
The affected products include various versions of FFmpeg, specifically versions 7.0, 7.1, 7.2, and 8.0, along with Debian Linux 11.0. This broad impact underscores the importance of diligent patch management.
This vulnerability was published on February 18, 2025, and it remains crucial for organizations to stay updated on remediation efforts provided by vendors.
Technical Analysis
The root cause of this vulnerability stems from a segmentation violation, which occurs when a program attempts to access a memory segment that is not allocated or is not permitted. This could lead to unexpected behavior or crashes within the application.
The attack vector is network-based, allowing remote attackers to exploit this vulnerability. Given the low attack complexity and the requirement for user interaction, an attacker may need to lure a user into opening a malicious file that triggers the segmentation violation.
The availability impact is rated as high, indicating that successful exploitation can lead to a complete denial of service for the affected application. However, there is no confidentiality or integrity impact associated with this vulnerability.
Risk & Impact Analysis
Real-world deployment of this vulnerability can pose significant risks to organizations utilizing FFmpeg as part of their media processing workflows. The potential for denial of service means that critical applications could be rendered inoperable, leading to service disruptions.
This vulnerability matters to organizations particularly in sectors where media processing is essential. The blast radius could extend to any application relying on FFmpeg, potentially affecting numerous users and workflows.
With a CVSS score of 6.5 and its classification as a medium severity vulnerability, organizations should address this in their priority patch cycle to minimize risks.
