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 filter_frame function in libavfilter/vf_fps.c in FFmpeg before 2.1 does not properly ensure the availability of FIFO content, which allows remote attackers to cause a denial of service (double free) or possibly have unspecified other impact via crafted data.

The ff_combine_frame function in libavcodec/parser.c in FFmpeg before 2.1 does not properly handle certain memory-allocation errors, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted 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.

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.

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.

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.

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.

libavcodec/alsdec.c in FFmpeg before 1.0.4 allows remote attackers to have an unspecified impact via a crafted block length, which triggers an out-of-bounds write.
