Ffmpeg: null pointer dereference in firequalizer filter (libavfilter/af_firequalizer.c)
A NULL pointer dereference vulnerability exists in FFmpeg’s Firequalizer filter (libavfilter/af_firequalizer.c) due to a missing check on the return value of av_malloc_array() in the config_input() function. An attacker could exploit this by tricking a victim…

Heap-buffer-overflow write in FFmpeg SANM process_ftch
It is possible to cause an use-after-free write in SANM decoding with a carefully crafted animation using subversion <2. When a STOR chunk is present, a subsequent FOBJ chunk will be saved in ctx->stored_frame. Stored frames can later be referenced by FTCH ch…

Heap-buffer-overflow write in FFmpeg EXR dwa_uncompress
When decoding an OpenEXR file that uses DWAA or DWAB compression, there's an implicit assumption that all image channels have the same pixel type (and size), and that if there are four channels, the first four are "B", "G", "R" and "A". The channel parsing co…

Heap-buffer-overflow write in FFmpeg EXR dwa_uncompress
When decoding an OpenEXR file that uses DWAA or DWAB compression, there's an implicit assumption that the height and width are divisible by 8. If the height or width of the image is not divisible by 8, the copy loops at [0] and [1] will continue to write unti…

Heap-buffer-overflow write in FFmpeg EXR dwa_uncompress
When decoding an OpenEXR file that uses DWAA or DWAB compression, the specified raw length of run-length-encoded data is not checked when using it to calculate the output data. We read rle_raw_size from the input file at [0], we decompress and decode into the…

Heap-buffer-overflow write in FFmpeg SANM decoding due to lack of bounds-checking in old_codec48
When decoding a frame for a SANM file (ANIM v0 variant), the decoded data can be larger than the buffer allocated for it. Frames encoded with codec 48 can specify their resolution (width x height). A buffer of appropriate size is allocated depending on the re…

Heap-buffer-overflow read in FFmpeg DHAV get_duration
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) …

Remote code execution via Heap Buffer Overflow in FFmpeg JPEG2000
A heap-buffer-overflow write exists in jpeg2000dec FFmpeg which allows an attacker to potentially gain remote code execution or cause denial of service via the channel definition cdef atom of JPEG2000.
