CVE-2025-55651: n/a
A NULL pointer dereference in the gf_isom_get_user_data_count function (isomedia/isom_read.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
AI Analysis
Technical Summary
The vulnerability involves a NULL pointer dereference in the gf_isom_get_user_data_count function within the isomedia/isom_read.c source file of GPAC MP4Box version 2.4. An attacker can exploit this by supplying a crafted MP4 file, causing the application to crash and resulting in a Denial of Service. There is no CVSS score or detailed vendor advisory available, and no information about patches or mitigations has been provided.
Potential Impact
Successful exploitation causes a Denial of Service by crashing the GPAC MP4Box application when processing malicious MP4 files. This disrupts normal operation but does not indicate data compromise or code execution based on the available information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid processing untrusted or suspicious MP4 files with GPAC MP4Box v2.4.
