A local, authenticated attacker can bypass the passcode in the VideoLAN VLC media player app before 3.1.5 for iOS by opening a URL and turning the phone.

The CAF demuxer in modules/demux/caf.c in VideoLAN VLC media player 3.0.4 may read memory from an uninitialized pointer when processing magic cookies in CAF files, because a ReadKukiChunk() cast converts a return value to an unsigned int even if that value is negative. This could result in a denial of service and/or a potential infoleak.

VideoLAN VLC media player 2.2.x is prone to a use after free vulnerability which an attacker can leverage to execute arbitrary code via crafted MKV files. Failed exploit attempts will likely result in denial of service conditions.

The vlc_demux_chained_Delete function in input/demux_chained.c in VideoLAN VLC media player 3.0.1 allows remote attackers to cause a denial of service (heap corruption and application crash) or possibly have unspecified other impact via a crafted .swf file.

In VideoLAN VLC media player through 2.2.8, there is a type conversion vulnerability in modules/demux/mp4/libmp4.c in the MP4 demux module leading to a invalid free, because the type of a box may be changed between a read operation and a free operation.

avcodec 2.2.x, as used in VideoLAN VLC media player 2.2.7-x before 2017-06-29, allows out-of-bounds heap memory write due to calling memcpy() with a wrong size, leading to a denial of service (application crash) or possibly code execution.

plugins\codec\libflac_plugin.dll in VideoLAN VLC media player 2.2.4 allows remote attackers to cause a denial of service (heap corruption and application crash) or possibly have unspecified other impact via a crafted FLAC file.

plugins\audio_filter\libmpgatofixed32_plugin.dll in VideoLAN VLC media player 2.2.4 allows remote attackers to cause a denial of service (invalid read and application crash) or possibly have unspecified other impact via a crafted file.

Potential heap based buffer overflow in ParseJSS in VideoLAN VLC before 2.2.5 due to skipping NULL terminator in an input string allows attackers to execute arbitrary code via a crafted subtitles file.

Heap out-of-bound read in ParseJSS in VideoLAN VLC before 2.2.5 due to missing check of string termination allows attackers to read data beyond allocated memory and potentially crash the process via a crafted subtitles file.
