CVE-2023-50009: n/a in n/a
FFmpeg v.n6.1-3-g466799d4f5 allows a heap-based buffer overflow via the ff_gaussian_blur_8 function in libavfilter/edge_template.c:116:5 component.
AI Analysis
Technical Summary
CVE-2023-50009 is a high-severity heap-based buffer overflow vulnerability identified in FFmpeg, specifically within the ff_gaussian_blur_8 function located in the libavfilter/edge_template.c source file. FFmpeg is a widely used open-source multimedia framework that handles video, audio, and other multimedia files and streams. The vulnerability arises when the ff_gaussian_blur_8 function processes input data, leading to a heap-based buffer overflow condition. This type of overflow occurs when data is written beyond the allocated heap memory buffer, potentially corrupting adjacent memory and enabling an attacker to manipulate program execution flow. The CVSS v3.1 score of 8.0 reflects a high severity level, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), low confidentiality impact (C:L), high integrity impact (I:H), and high availability impact (A:H). This means an attacker with local access can exploit the vulnerability without any special privileges or user interaction, potentially causing significant integrity and availability damage, such as arbitrary code execution or application crashes. Although no known exploits are currently reported in the wild, the nature of the vulnerability and the critical role of FFmpeg in multimedia processing make it a significant risk. The lack of specific affected versions and vendor information suggests the need for users to verify their FFmpeg versions and monitor for official patches. The vulnerability is classified under CWE-122, which corresponds to heap-based buffer overflows, a common and dangerous class of memory corruption issues.
Potential Impact
For European organizations, the impact of CVE-2023-50009 can be substantial due to the widespread use of FFmpeg in various applications, including media servers, streaming platforms, video conferencing tools, and content delivery networks. Exploitation could lead to unauthorized code execution, data corruption, or denial of service, affecting service availability and data integrity. Organizations relying on multimedia processing for critical communications, broadcasting, or content distribution may experience operational disruptions. Furthermore, sectors such as media, telecommunications, and government agencies that handle sensitive multimedia data could face confidentiality risks, although the confidentiality impact is rated low. The local attack vector implies that attackers need some form of local access, which could be achieved through compromised user accounts or insider threats. Given the high integrity and availability impacts, successful exploitation could undermine trust in digital services and cause financial and reputational damage. Additionally, the lack of user interaction required for exploitation increases the risk of automated or stealthy attacks once local access is obtained.
Mitigation Recommendations
European organizations should take immediate steps to mitigate this vulnerability. First, they should identify all systems and applications using FFmpeg, especially those involved in multimedia processing. Since no official patch links are currently available, organizations should monitor FFmpeg's official repositories and security advisories for updates addressing CVE-2023-50009. In the interim, applying strict input validation and sanitization on multimedia data processed by FFmpeg can reduce exploitation risk. Employing application whitelisting and sandboxing techniques can limit the impact of potential exploits by isolating FFmpeg processes. Restricting local access to trusted users and enforcing strong authentication and access controls will reduce the likelihood of attackers gaining the necessary local access. Network segmentation can further contain compromised systems. Additionally, organizations should implement runtime protections such as Address Space Layout Randomization (ASLR) and Data Execution Prevention (DEP) to hinder exploitation of memory corruption vulnerabilities. Regular security audits and monitoring for unusual application behavior or crashes related to FFmpeg usage are also recommended to detect potential exploitation attempts early.
