Certain VLC media player builds in versions 3.0.0 through 3.0.23 contain a memory-safety vulnerability reachable when processing media from an attacker-controlled network source. Exploitation requires user interaction and may disclose a limited, layout-dependent amount of VLC process memory. Exposure depends on build configuration.
