CVE-2025-55657: A NULL pointer dereference in the gf_odf_vvc_cfg_write_bs function (odf/descriptors.c) of GPAC MP4Box v2.4...
A NULL pointer dereference in the gf_odf_vvc_cfg_write_bs function (odf/descriptors.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
Security readout for executives and security teams
CVE-2025-55657 is a denial-of-service issue in GPAC MP4Box v2.4. A specially crafted MP4 file can trigger a NULL pointer dereference and crash processing. The disclosed impact is availability loss, not data theft or code execution. Public sources do not show active exploitation or a named patch. Organizations are most exposed where GPAC MP4Box v2.4 processes untrusted or externally supplied MP4 files, especially in media pipelines, upload workflows, transcoding, packaging, QA, or automated file-analysis services. Treat as high priority for media-processing environments handling outside files. The business risk is service disruption and pipeline outage, not confirmed data compromise. Prioritize inventory, isolation, and vendor update tracking. Mitigation focus: Identify systems using GPAC MP4Box v2.4.; Avoid processing untrusted MP4 files with affected MP4Box deployments.; Isolate media-processing jobs from critical services..

Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
