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.

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.

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.

Multiple integer signedness errors in libavcodec/dsputil.c in FFmpeg before 2.1 allow remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted 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 decode_frame_ilbm function in libavcodec/iff.c in FFmpeg before 1.1 allows remote attackers to have an unspecified impact via a crafted height value in IFF PBM/ILBM bitmap data.

The mjpeg_decode_scan_progressive_ac function in libavcodec/mjpegdec.c in FFmpeg before 1.1 allows remote attackers to have an unspecified impact via crafted MJPEG data.

The decode_frame function in libavcodec/eamad.c in FFmpeg before 1.1 allows remote attackers to have an unspecified impact via crafted Electronic Arts Madcow video data, which triggers an out-of-bounds array access.

The add_doubles_metadata function in libavcodec/tiff.c in FFmpeg before 1.1 allows remote attackers to have an unspecified impact via a negative or zero count value in a TIFF image, which triggers an out-of-bounds array access.
