It was discovered that the VLC CAF demuxer incorrectly handled certain

remote attacker could use this issue to cause VLC to crash, resulting in a
denial of service, or possibly execute arbitrary code. (CVE-2019-12874)

It was discovered that the VLC MP4 demuxer incorrectly handled certain
files. If a user were tricked into opening a specially-crafted MP4 file, a

denial of service, or possibly execute arbitrary code. (CVE-2019-13602)

It was discovered that the VLC AVI demuxer incorrectly handled certain
files. If a user were tricked into opening a specially-crafted AVI file, a
remote attacker could use this issue to cause VLC to crash, resulting in a
denial of service, or possibly execute arbitrary code. (CVE-2019-5439)
