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.
In plain language
Written by AI from the recordVLC media player 3.0.0 through 3.0.23 can reveal small pieces of internal information after someone opens a malicious media file, so businesses using it should act now.
A network-delivered, user-assisted out-of-bounds memory-read/incomplete-string-termination flaw in specific VLC builds may disclose limited, layout-dependent process memory.
