CVE-2023-23145Public exploit

Memory leak via overwritten stroke-dash array allocations

Published Jan 20, 2023 · Updated Apr 3, 2025

Memory leak in GPAC 2.2-rev0-gab012bbfb-master allows local users to consume process memory by opening a crafted LASeR file. In lsr_read_rare_full, each parsed stroke-dash array replaced the vals and units pointers with new allocations without releasing the prior buffers. User interaction is required to process the file; the published proof of concept demonstrates a 220-byte leak, not a crash.
