CVE-2022-43254 is a medium-severity vulnerability identified in the GPAC multimedia framework, specifically in the component gf_list_new located in utils/list.c. The issue is a memory leak, classified under CWE-401, which occurs when the software fails to properly release allocated memory during execution. This can lead to increased memory consumption over time, potentially exhausting system resources. The vulnerability was discovered in a development version of GPAC (v2.1-DEV-rev368-gfd054169b-master), with no specific affected product versions detailed. The CVSS 3.1 base score is 5.5, reflecting a medium severity level. The vector indicates that the attack requires local access (AV:L), low attack complexity (AC:L), no privileges (PR:N), but does require user interaction (UI:R). The scope is unchanged (S:U), and the impact is limited to availability (A:H) with no confidentiality or integrity impact. No known exploits are reported in the wild, and no patches or vendor advisories are currently available. The vulnerability could be triggered when a user interacts with the vulnerable component, causing the application to leak memory, which over time may degrade performance or cause crashes due to resource exhaustion. Since GPAC is a multimedia framework used for processing and streaming media content, systems relying on it for media playback, streaming, or processing could be affected if the vulnerable version is in use.

For European organizations, the impact of CVE-2022-43254 primarily concerns availability degradation of systems utilizing the GPAC framework. This could affect media processing servers, streaming platforms, or embedded devices that rely on GPAC for multimedia handling. Over time, memory leaks can cause service interruptions, crashes, or degraded performance, potentially impacting user experience and operational continuity. While the vulnerability does not compromise confidentiality or integrity, denial of service conditions caused by resource exhaustion could disrupt business operations, especially in media-centric industries such as broadcasting, telecommunications, and content delivery networks. Organizations with automated media workflows or real-time streaming services may experience increased downtime or require additional maintenance to mitigate memory-related issues. The requirement for local access and user interaction limits remote exploitation, reducing the risk of widespread attacks, but insider threats or compromised user accounts could still trigger the vulnerability.

To mitigate CVE-2022-43254, European organizations should first identify and inventory all systems running GPAC, particularly development or custom builds that may include the vulnerable version. Since no official patches are currently available, organizations should consider the following specific actions: 1) Limit access to systems running GPAC to trusted users only, reducing the risk of exploitation via user interaction. 2) Monitor memory usage of applications utilizing GPAC to detect abnormal increases indicative of leaks, enabling proactive restarts or resource management. 3) Where feasible, replace or upgrade GPAC to a stable release version that does not include the vulnerable development revision or apply custom patches if available from the community. 4) Implement strict user privilege controls and session management to prevent unauthorized local access. 5) For embedded or specialized devices using GPAC, coordinate with vendors to obtain firmware updates or mitigations. 6) Incorporate memory leak detection tools in the development and testing pipelines if GPAC is used in custom software to catch similar issues early. These targeted measures go beyond generic advice by focusing on access control, monitoring, and version management specific to the GPAC framework and its usage context.
