CVE-2022-1795Public exploit

Local process crash via BIFS node lifetime error

Published May 18, 2022 · Updated Aug 3, 2024

Use-after-free in GPAC before 2.1.0-DEV allows local users to crash MP4Box by processing a crafted BIFS scene file. In BM_ParseGlobalQuantizer, an invalid reused node is unregistered despite existing references, leaving scene teardown to read freed memory in gf_node_try_destroy. The published proof invokes MP4Box's -bt path and demonstrates an AddressSanitizer abort; the report lists code execution as possible but does not demonstrate it.
