Videolan » Vlc Media Player : Security Vulnerabilities, CVEs, CVSS score >= 8

Videolan VLC prior to version 3.0.20 contains an incorrect offset read that leads to a Heap-Based Buffer Overflow in function GetPacket() and results in a memory corruption.

lavc_CopyPicture in modules/codec/avcodec/video.c in VideoLAN VLC media player through 3.0.7 has a heap-based buffer over-read because it does not properly validate the width and height.

An issue was discovered in zlib_decompress_extra in modules/demux/mkv/util.cpp in VideoLAN VLC media player 3.x through 3.0.7. The Matroska demuxer, while parsing a malformed MKV file type, has a double free.

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.

Buffer overflow in the DecodeAdpcmImaQT function in modules/codec/adpcm.c in VideoLAN VLC media player before 2.2.4 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted QuickTime IMA file.

Multiple buffer overflows in VideoLAN VLC media player 2.0.4 and earlier allow remote attackers to cause a denial of service (crash) and execute arbitrary code via vectors related to the (1) freetype renderer and (2) HTML subtitle parser.

Multiple heap-based buffer overflows in VideoLAN VLC media player before 2.0.1 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted Real RTSP stream.

Stack-based buffer overflow in VideoLAN VLC media player before 2.0.1 allows remote attackers to execute arbitrary code via a crafted MMS:// stream.

Double free vulnerability in the get_chunk_header function in modules/demux/ty.c in VideoLAN VLC media player 0.9.0 through 1.1.12 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TiVo (TY) file.

Integer overflow in the XSPF playlist parser in VideoLAN VLC media player 0.8.5 through 1.1.9 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors that trigger a heap-based buffer overflow.

demux/mkv/mkv.hpp in the MKV demuxer plugin in VideoLAN VLC media player 1.1.6.1 and earlier allows remote attackers to cause a denial of service (crash) and execute arbitrary commands via a crafted MKV (WebM or Matroska) file that triggers memory corruption, related to "class mismatching" and the MKV_IS_ID macro.

Multiple heap-based buffer overflows in cdg.c in the CDG decoder in VideoLAN VLC Media Player before 1.1.6 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted CDG video.

Multiple integer overflows in real.c in the Real demuxer plugin in VideoLAN VLC Media Player before 1.1.6 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a zero i_subpackets value in a Real Media file, leading to a heap-based buffer overflow.

libdirectx_plugin.dll in VideoLAN VLC Media Player before 1.1.8 allows remote attackers to execute arbitrary code via a crafted width in an NSV file.

libdirectx_plugin.dll in VideoLAN VLC Media Player before 1.1.8 allows remote attackers to execute arbitrary code via a crafted width in an AMV file, related to a "dangling pointer vulnerability."

Untrusted search path vulnerability in bin/winvlc.c in VLC Media Player 1.1.3 and earlier allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse wintab32.dll that is located in the same folder as a .mp3 file.

Stack-based buffer overflow in VideoLAN VLC Media Player 0.8.6 allows user-assisted remote attackers to execute arbitrary code via an ogg file with a crafted Advanced SubStation Alpha Subtitle (.ass) file, probably involving the Dialogue field.

Stack-based buffer overflow in the Win32AddConnection function in modules/access/smb.c in VideoLAN VLC media player 0.9.9, when running on Microsoft Windows, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a long smb URI in a playlist file.

Integer overflow in the ReadRealIndex function in real.c in the Real demuxer plugin in VideoLAN VLC media player 0.9.0 through 0.9.7 allows remote attackers to execute arbitrary code via a malformed RealMedia (.rm) file that triggers a heap-based buffer overflow.

Stack-based buffer overflow in VideoLAN VLC media player 0.9.x before 0.9.6 might allow user-assisted attackers to execute arbitrary code via an an invalid RealText (rt) subtitle file, related to the ParseRealText function in modules/demux/subtitle.c. NOTE: this issue was SPLIT from CVE-2008-5032 on 20081110.

Stack-based buffer overflow in VideoLAN VLC media player 0.5.0 through 0.9.5 might allow user-assisted attackers to execute arbitrary code via the header of an invalid CUE image file, related to modules/access/vcd/cdrom.c. NOTE: this identifier originally included an issue related to RealText, but that issue has been assigned a separate identifier, CVE-2008-5036.
