L-SMASH through 2.14.5 contains a double free vulnerability in hevc setup first summary() and h264 setup first summary() in importer/nalu imp.c that frees borrowed codec-specific objects on error paths. Attackers can supply a crafted Annex-B elementary stream lacking a parseable SPS to lsmash read file() or the boxdumper, remuxer, or muxer tools, causing use-after-free, heap corruption, and crashes.
