CVSS v3.1 |
| FFmpeg's RASC video decoder (decode_dlta in libavcodec/rasc.c) performs 32-bit reads and writes at the row cursor before the NEXT_LINE row-boundary check and validates the DLTA region in pixel rather than byte units, so a DLTA run on a PAL8 frame can access several bytes past the row allocation. A crafted media stream using the RASC FourCC, decoded by libavcodec, triggers a bitstream-controlled out-of-bounds heap write and adjacent out-of-bounds read, leading to memory corruption. |
| A use-after-free vulnerability was found in FFmpeg's RASC video decoder. The decode_move() function initializes a read pointer into a decompressed buffer, but a subsequent reallocation of that same buffer during move-table processing leaves the pointer dangling. An attacker could exploit this by providing a specially crafted AVI file containing a malicious RASC video stream. When a user opens or plays the file, the decoder reads from freed heap memory, which could lead to a denial of service (crash). |
| An out-of-bounds write vulnerability in FFmpeg's libavcodec library, specifically in the MagicYUV decoder, allows denial-of-service and, in some cases, can be exploited for remote code execution.
This vulnerability is associated with the file libavcodec/magicyuv.C.
This issue affects FFmpeg before version 8.1.2. |
| A flaw was found in FFmpeg’s ALS audio decoder, where it does not properly check for memory allocation failures. This can cause the application to crash when processing certain malformed audio files. While it does not lead to data theft or system control, it can be used to disrupt services and cause a denial of service. |
| An out-of-bounds read in the read_global_param() function (libavcodec/av1dec.c) of FFmpeg v8.0.1 allows attackers to cause a Denial of Service (DoS) via a crafted input. |
| An improper resource deallocation and closure vulnerability in the tools/zmqsend.c component of FFmpeg v8.0.1 allows attackers to cause a Denial of Service (DoS) via supplying a crafted input file. |
| A heap buffer overflow in the av_bprint_finalize() function of FFmpeg v8.0.1 allows attackers to cause a Denial of Service (DoS) via a crafted input. |
| Buffer overflow in libavcodec/dca.c in FFmpeg 0.4.9 before r14917, as used by MPlayer, allows context-dependent attackers to have an unknown impact via vectors related to an incorrect DCA_MAX_FRAME_SIZE value. |
| Stack-based buffer overflow in the str_read_packet function in libavformat/psxstr.c in FFmpeg before r13993 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a crafted STR file that interleaves audio and video sectors. |
| Unspecified vulnerability in the avcodec_close function in libavcodec/utils.c in FFmpeg 0.4.9 before r14787, as used by MPlayer, has unknown impact and attack vectors, related to a free "on random pointers." |
| Multiple buffer overflows in libavformat/utils.c in FFmpeg 0.4.9 before r14715, as used by MPlayer, allow context-dependent attackers to have an unknown impact via vectors related to execution of DTS generation code with a delay greater than MAX_REORDER_DELAY. |
| Integer signedness error in the fourxm_read_header function in libavformat/4xm.c in FFmpeg before revision 16846 allows remote attackers to execute arbitrary code via a malformed 4X movie file with a large current_track value, which triggers a NULL pointer dereference. |
| FFmpeg 0.4.9, as used by MPlayer, allows context-dependent attackers to cause a denial of service (memory consumption) via unknown vectors, aka a "Tcp/udp memory leak." |
| FFmpeg before 8.1 has an integer overflow and resultant out-of-bounds write via CENC (Common Encryption) subsample data to libavformat/mov.c. |
| A flaw was found in FFmpeg. A remote attacker could exploit this vulnerability by providing a specially crafted MPEG-PS/VOB media file containing a malicious DVD subtitle stream. This vulnerability is caused by a signed integer overflow in the DVD subtitle parser's fragment reassembly bounds checks, leading to a heap out-of-bounds write. Successful exploitation can result in a denial of service (DoS) due to an application crash, and potentially lead to arbitrary code execution. |
| Heap-based buffer overflow in the avcodec_default_get_buffer function (utils.c) in FFmpeg libavcodec 0.4.9-pre1 and earlier, as used in products such as (1) mplayer, (2) xine-lib, (3) Xmovie, and (4) GStreamer, allows remote attackers to execute arbitrary commands via small PNG images with palettes. |
| Multiple buffer overflows in libavcodec in ffmpeg before 0.4.9_p20060530 allow remote attackers to cause a denial of service or possibly execute arbitrary code via multiple unspecified vectors in (1) dtsdec.c, (2) vorbis.c, (3) rm.c, (4) sierravmd.c, (5) smacker.c, (6) tta.c, (7) 4xm.c, (8) alac.c, (9) cook.c, (10) shorten.c, (11) smacker.c, (12) snow.c, and (13) tta.c. NOTE: it is likely that this is a different vulnerability than CVE-2005-4048 and CVE-2006-2802. |
| FFmpeg git master before commit fd1772 was discovered to contain a NULL pointer dereference via the component libavformat/mov.c. |
| FFmpeg git master before commit c08d30 was discovered to contain a memory leak in the avformat_free_context function in libavutil/mem.c. |
| When parsing the header for a DHAV file, there's an integer underflow in offset calculation that leads to reading the duration from before the start of the allocated buffer.
If we load a DHAV file that is larger than MAX_DURATION_BUFFER_SIZE bytes (0x100000) for example 0x101000 bytes, then at [0] we have size = 0x101000. At [1] we have end_buffer_size = 0x100000, and at [2] we have end_buffer_pos = 0x1000.
The loop then scans backwards through the buffer looking for the dhav tag; when it is found, we'll calculate end_pos based on a 32-bit offset read from the buffer.
There is subsequently a check [3] that end_pos is within the section of the file that has been copied into end_buffer, but it only correctly handles the cases where end_pos is before the start of the file or after the section copied into end_buffer, and not the case where end_pos is within the the file, but before the section copied into end_buffer. If we provide such an offset, (end_pos - end_buffer_pos) can underflow, resulting in the subsequent access at [4] occurring before the beginning of the allocation.
We recommend upgrading to version 8.0 or beyond. |
