GPAC MP4Box version 0.7.1 and earlier contains a Buffer Overflow vulnerability in src/isomedia/avc_ext.c lines 2417 to 2420 that can result in Heap chunks being modified, this could lead to RCE. This attack appear to be exploitable via an attacker supplied MP4 file that when run by the victim may result in RCE.

Security readout for executives and security teams

Plain-English summary

CVE-2018-1000100 is a GPAC MP4Box heap buffer overflow affecting version 0.7.1 and earlier. A malicious MP4 file processed by a vulnerable MP4Box instance could corrupt memory and may lead to remote code execution. The source bundle does not provide CVSS scoring or confirmed active exploitation.

Executive priority

Treat this as a high-priority remediation for systems that process untrusted MP4 files. Business urgency is lower for systems without GPAC MP4Box or without exposure to attacker-controlled media.

Technical view

The CVE describes a buffer overflow in GPAC MP4Box, specifically src/isomedia/avc_ext.c lines 2417 to 2420. The reported impact is heap chunk modification with possible RCE when a victim runs MP4Box on an attacker-supplied MP4 file. Ubuntu published USN-3926-1, but exact fixed versions are not included in the bundle.

Likely exposure

Exposure is most likely where GPAC MP4Box 0.7.1 or earlier is installed and processes MP4 files from users, partners, uploads, email attachments, or other untrusted sources.

Exploitation context

The bundle says exploitation appears possible through an attacker-supplied MP4 file processed by the victim. There is no KEV listing and no cited source in the bundle confirming active exploitation in the wild.

Researcher notes

Evidence is limited to the CVE description, GitHub issue reference, and Ubuntu advisory reference. The affected product is GPAC MP4Box 0.7.1 and earlier, but the bundle lacks CVSS, CWE, CPE, detailed patch versions, and confirmed exploitation evidence.

Mitigation direction

  • Identify GPAC MP4Box installations and confirm whether versions are 0.7.1 or earlier.
  • Apply vendor-supported GPAC or OS package updates where available.
  • Review Ubuntu USN-3926-1 for Ubuntu-specific remediation details.
  • Avoid processing untrusted MP4 files with vulnerable MP4Box versions.
  • Run media-processing workloads with least privilege and isolation.

Validation and detection

  • Check MP4Box versions on workstations, servers, CI images, and media-processing containers.
  • Find workflows that invoke MP4Box on externally supplied MP4 files.
  • Confirm updated packages or builds are deployed after remediation.
  • Verify vulnerable versions are removed from golden images and dependency manifests.
  • Review logs for unexpected crashes during MP4 parsing or processing.
