The get_siz function in libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not prevent attempts to use non-zero image offsets, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.

The g2m_init_buffers function in libavcodec/g2meet.c in FFmpeg before 2.1 does not properly allocate memory for tiles, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Go2Webinar data.

The rpza_decode_stream function in libavcodec/rpza.c in FFmpeg before 2.1 does not properly maintain a pointer to pixel data, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Apple RPZA data.

The get_cox function in libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not properly validate the reduction factor, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.

The get_siz function in libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not ensure the expected sample separation, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.

Integer signedness error in the add_bytes_l2_c function in libavcodec/pngdsp.c in FFmpeg before 2.1 allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted PNG data.

libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not ensure the use of valid code-block dimension values, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.

The g2m_init_buffers function in libavcodec/g2meet.c in FFmpeg before 2.1 uses an incorrect ordering of arithmetic operations, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Go2Webinar data.

The flashsv_decode_frame function in libavcodec/flashsv.c in FFmpeg before 2.1 does not properly validate a certain height value, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Flash Screen Video data.

The read_header function in libavcodec/ffv1dec.c in FFmpeg before 2.1 does not prevent changes to global parameters, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted FFV1 data.

The jpeg2000_decode_tile function in libavcodec/jpeg2000dec.c in FFmpeg before 2.1 does not consider the component number in certain calculations, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG2000 data.

libavcodec/jpeg2000.c in FFmpeg before 2.1 allows remote attackers to cause a denial of service (invalid pointer dereference) or possibly have unspecified other impact via crafted JPEG2000 data.

The jpeg2000_read_main_headers function in libavcodec/jpeg2000dec.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not enforce uniqueness of the SIZ marker in a JPEG 2000 image, which allows remote attackers to cause a denial of service (out-of-bounds heap-memory access) or possibly have unspecified other impact via a crafted image with two or more of these markers.

A heap-based Buffer Overflow vulnerability exists FFmpeg 4.2 at libavfilter/vf_floodfill.c, which might lead to memory corruption and other potential consequences.

An issue was discovered in function latm_write_packet in libavformat/latmenc.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts due to a Null pointer dereference.

A heap-based Buffer Overflow vulnerability exists in FFmpeg 4.2 in filter_intra at libavfilter/vf_bwdif.c, which might lead to memory corruption and other potential consequences.

Buffer Overflow vulnerability in function config_input in libavfilter/vf_gblur.c in Ffmpeg 4.2.1, allows attackers to cause a Denial of Service or other unspecified impacts.

FFmpeg through 4.3 has a heap-based buffer overflow in avio_get_str in libavformat/aviobuf.c because dnn_backend_native.c calls ff_dnn_load_model_native and a certain index check is omitted.
