Cvss 3 Severity Score

GPAC version 0.7.1 and earlier has a buffer overflow vulnerability in the cat_multiple_files function in applications/mp4box/fileimport.c when MP4Box is used for a local directory containing crafted filenames.

From the Ubuntu Security Team

It was discovered that the GPAC MP4Box utility incorrectly handled certain memory operations. If an user or automated system were tricked into opening a specially crafted MP4 file, a remote attacker could use this issue to cause MP4Box to crash, resulting in a denial of service, or possibly execute arbitrary code.
