VideoLAN VLC for Android prior to version 3.7.0 contains a path traversal vulnerability in the Remote Access Server routing for the authenticated endpoint GET /download. The file query parameter is concatenated into a filesystem path under the configured download directory without canonicalization or directory containment checks, allowing an authenticated attacker with network reachability to the Remote Access Server to request files outside the intended directory. The impact is bounded by the Android application sandbox and storage restrictions, typically limiting exposure to app-internal and app-specific external storage.

VideoLAN VLC for Android prior to version 3.7.0 contains an authentication bypass in the Remote Access Server feature due to missing or insufficient rate limiting on one-time password (OTP) verification. The Remote Access Server uses a 4-digit OTP and does not enforce effective throttling or lockout within the OTP validity window, allowing an attacker with network reachability to the server to repeatedly attempt OTP verification until a valid usersession cookie is issued. Successful exploitation results in unauthorized access to the Remote Access interface, limited to media files explicitly shared by the VLC for Android user.

A vulnerability in EbmlTypeDispatcher::send in VideoLAN VLC media player 3.0.11 allows attackers to trigger a heap-based buffer overflow via a crafted .mkv file.

An integer overflow in dav1d AV1 decoder that can occur when decoding videos with large frame size. This can lead to memory corruption within the AV1 decoder. We recommend upgrading past version 1.4.0 of dav1d.

The ASFReadObjectfileproperties function in modules/demux/asf/libasf.c in the ASF Demuxer in VideoLAN VLC Media Player before 2.1.3 allows remote attackers to cause a denial of service (divide-by-zero error and crash) via a zero minimum and maximum data packet size in an ASF file.

VideoLAN VLC Media Player before 2.0.7 allows remote attackers to cause a denial of service (memory consumption) via a crafted playlist file.

The parseRTSPRequestString function in Live Networks Live555 Streaming Media 2013.11.26, as used in VideoLAN VLC Media Player, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a space character at the beginning of an RTSP message, which triggers an integer underflow, infinite loop, and buffer overflow. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-6933.

VideoLAN VLC Media Player 2.0.8 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long string in a URL in a m3u file.

requests/status.xml in VLC 0.9.8a allows remote attackers to cause a denial of service (stack consumption and crash) via a long input argument in an inplay action.
