The host is installed with VideoLAN VLC media player through 3.0.11 and is prone to a heap-based buffer overflow vulnerability. A flaw is present in the application, which fails to properly handle issues in the hxxx_AnnexB_to_xVC function in modules/packetizer/hxxx_nal.c. Successful exploitation could leads to a denial of service or execute arbitrary code via a crafted H.264 Annex-B video (.avi for example) file.
