An off-by-one error in the DecodeBlock function in codec/sdl_image.c in VideoLAN VLC media player before 3.0.9 allows remote attackers to cause a denial of service (memory corruption) via a crafted image file. NOTE: this may be related to the SDL_Image product.

The web interface in VideoLAN VLC media player before 2.0.7 has no access control which allows remote attackers to view directory listings via the 'dir' command or issue other commands without authenticating.

Multiple cross-site scripting (XSS) vulnerabilities in the HTTP Interface in VideoLAN VLC Media Player before 2.0.7 allow remote attackers to inject arbitrary web script or HTML via the (1) command parameter to requests/vlm_cmd.xml, (2) dir parameter to requests/browse.xml, or (3) URI in a request, which is returned in an error message through share/lua/intf/http.lua.

The MP4_ReadBox_String function in modules/demux/mp4/libmp4.c in VideoLAN VLC media player before 2.1.6 allows remote attackers to trigger an unintended zero-size malloc and conduct buffer overflow attacks, and consequently execute arbitrary code, via a box size of 7.

The rtp_packetize_xiph_config function in modules/stream_out/rtpfmt.c in VideoLAN VLC media player before 2.1.6 uses a stack-allocation approach with a size determined by arbitrary input data, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted length value.

Integer overflow in the Encode function in modules/codec/schroedinger.c in VideoLAN VLC media player before 2.1.6 and 2.2.x before 2.2.1 allows remote attackers to conduct buffer overflow attacks and execute arbitrary code via a crafted length value.

The GetUpdateFile function in misc/update.c in the Updater in VideoLAN VLC media player before 2.1.6 performs an incorrect cast operation from a 64-bit integer to a 32-bit integer, which allows remote attackers to conduct buffer overflow attacks and execute arbitrary code via a crafted update status file, aka an "integer truncation" vulnerability.

The MP4_ReadBox_String function in modules/demux/mp4/libmp4.c in VideoLAN VLC media player before 2.1.6 performs an incorrect cast operation from a 64-bit integer to a 32-bit integer, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a large box size.

Integer underflow in the MP4_ReadBox_String function in modules/demux/mp4/libmp4.c in VideoLAN VLC media player before 2.1.6 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a box size less than 7.

When executing VideoLAN VLC media player 3.0.8 with libqt on Windows, Data from a Faulting Address controls Code Flow starting at libqt_plugin!vlc_entry_license__3_0_0f+0x00000000003b9aba. NOTE: the VideoLAN security team indicates that they have not been contacted, and have no way of reproducing this issue.
