Technical Analysis

CVE-2022-43255 is a medium-severity vulnerability identified in the GPAC multimedia framework, specifically in the component gf_odf_new_iod located in the odf/odf_code.c source file. The vulnerability is characterized as a memory leak (CWE-401), which occurs when the software improperly manages memory allocations, failing to release memory that is no longer needed. This can lead to increased memory consumption over time, potentially exhausting system resources. The affected version is noted as GPAC v2.1-DEV-rev368-gfd054169b-master, a development build of the GPAC framework. The CVSS 3.1 base score is 5.5, indicating a medium severity level. The vector string (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) reveals that exploitation requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), and user interaction (UI:R). The impact is limited to availability (A:H), with no confidentiality or integrity impact. There are no known public exploits or patches currently available. The vulnerability arises when a user triggers the vulnerable code path, causing the memory leak to manifest, which could degrade system performance or cause denial of service over time if exploited repeatedly or in resource-constrained environments. The GPAC framework is commonly used for multimedia processing, including packaging and streaming of media content, which may be embedded in various applications and devices.

Potential Impact

For European organizations, the primary impact of this vulnerability lies in potential denial of service conditions due to memory exhaustion on systems running affected GPAC versions. Organizations utilizing GPAC for multimedia streaming, content packaging, or media playback in critical infrastructure, broadcasting, or media production environments could experience degraded service availability. Although the vulnerability does not compromise confidentiality or integrity, prolonged exploitation could disrupt media services, impacting user experience and operational continuity. This is particularly relevant for media companies, broadcasters, and any enterprise relying on GPAC-based solutions for content delivery. The requirement for local access and user interaction limits remote exploitation, reducing the risk for large-scale automated attacks but increasing risk in environments where untrusted users have local access or where malicious media files could be opened by users. Given the absence of known exploits, the immediate threat level is moderate, but organizations should remain vigilant, especially those with high multimedia processing workloads.

Mitigation Recommendations

To mitigate this vulnerability, European organizations should: 1) Identify and inventory all systems and applications using GPAC, especially development or custom builds similar to v2.1-DEV-rev368-gfd054169b-master. 2) Monitor memory usage patterns on systems running GPAC to detect abnormal increases that may indicate exploitation attempts. 3) Restrict local access to trusted users only, minimizing the risk of exploitation requiring user interaction. 4) Implement strict controls on media file sources, ensuring that only trusted media content is processed by GPAC components to reduce the risk of triggering the memory leak via crafted files. 5) Engage with GPAC maintainers or community to obtain patches or updates addressing this memory leak as they become available, and apply them promptly. 6) Consider sandboxing or isolating GPAC processes to limit the impact of potential resource exhaustion. 7) Educate users about the risks of opening untrusted media files in environments using GPAC. These steps go beyond generic advice by focusing on access control, monitoring, and operational practices tailored to the nature of this vulnerability.
