A flaw has been found in GPAC 26.02.0. This affects the function nhmldump_send_frame of the file src/filters/write_nhml.c of the component Media File Handler. Executing a manipulation can lead to null pointer dereference. The attack requires local access. The exploit has been published and may be used. This patch is called bd1d94e70e3bef364c07c5a1d94eca5c9f56e160. A patch should be applied to remediate this issue. The project explains: "I would consider most of these more as bugs than vulns but anyway they're good to fix".
