A vulnerability, which was classified as critical, was found in FFmpeg up to 5.1.5. This affects the function fill_audiodata of the file /libswresample/swresample.c. The manipulation leads to heap-based buffer overflow. It is possible to initiate the attack remotely. This issue was fixed in version 6.0 by 9903ba28c28ab18dc7b7b6fb8571cc8b5caae1a6 but a backport for 5.1 was forgotten. The exploit has been disclosed to the public and may be used. Upgrading to version 5.1.6 and 6.0 9903ba28c28ab18dc7b7b6fb8571cc8b5caae1a6 is able to address this issue. It is recommended to upgrade the affected component.

Integer overflow vulnerability in FFmpeg before n6.1, allows attackers to cause a denial of service (DoS) via the avcodec/osq module.

Integer overflow vulnerability in FFmpeg before n6.1, allows remote attackers to execute arbitrary code via the JJPEG XL Parser.

Integer overflow vulnerability in FFmpeg before n6.1, allows remote attackers to execute arbitrary code via the jpegxl_anim_read_packet component in the JPEG XL Animation decoder.

Buffer Overflow vulnerability in Ffmpeg before github commit 4565747056a11356210ed8edcecb920105e40b60 allows a remote attacker to achieve an out-of-array write, execute arbitrary code, and cause a denial of service (DoS) via the ref_pic_list_struct function in libavcodec/evc_ps.c

FFmpeg prior to commit bf814 was discovered to contain an out of bounds read via the dist->alphabet_size variable in the read_vlc_prefix() function.

libavcodec/pthread_frame.c in FFmpeg before 5.1.2, as used in VLC and other products, leaves stale hwaccel state in worker threads, which allows attackers to trigger a use-after-free and execute arbitrary code in some circumstances (e.g., hardware re-initialization upon a mid-video SPS change when Direct3D11 is used).

A null pointer dereference issue was discovered in 'FFmpeg' in decode_main_header() function of libavformat/nutdec.c file. The flaw occurs because the function lacks check of the return value of avformat_new_stream() and triggers the null pointer dereference error, causing an application to crash.

An issue was discovered in the FFmpeg package, where vp3_decode_frame in libavcodec/vp3.c lacks check of the return value of av_malloc() and will cause a null pointer dereference, impacting availability.

An integer overflow vulnerability was found in FFmpeg versions before 4.4.2 and before 5.0.1 in g729_parse() in llibavcodec/g729_parser.c when processing a specially crafted file.

FFmpeg N-98388-g76a3ee996b allows attackers to cause a denial of service (DoS) via a crafted audio file due to insufficient verification of data authenticity.

A heap-use-after-free in the mpeg_mux_write_packet function in libavformat/mpegenc.c of FFmpeg 4.2 allows to cause a denial of service (DOS) via a crafted avi file.

A heap-use-after-free in the av_freep function in libavutil/mem.c of FFmpeg 4.2 allows attackers to execute arbitrary code.

Prior to ffmpeg version 4.3, the tty demuxer did not have a 'read_probe' function assigned to it. By crafting a legitimate "ffconcat" file that references an image, followed by a file the triggers the tty demuxer, the contents of the second file will be copied into the output file verbatim (as long as the `-vcodec copy` option is passed to ffmpeg).

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the config_input function in af_acrossover.c.

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the av_dict_set function in dict.c.

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the filter_frame function in vf_tile.c.

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the wtvfile_open_sector function in wtvdec.c.

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the ff_frame_pool_get function in framepool.c.

A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the avpriv_float_dsp_allocl function in libavutil/float_dsp.c.
