Memory exhaustion via leaked DIMS parser buffer
Published Nov 29, 2022 · Updated Apr 25, 2025
Memory leak in dimC_box_read in GPAC 2.1-DEV-rev428-gcb8ae46c8-master allows local users to exhaust memory via a crafted DIMS file. The function allocates a temporary buffer from the declared dimC box size, then a failed bounds check in the second string-reading loop returns before that buffer is freed. Processing the file with MP4Box is required; repeated invocations consume process memory and can interrupt the application.
