Hi,

the following vulnerabilities were published for ffmpeg.

CVE-2015-8363[0]:
| 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.

CVE-2015-8364[1]:
| Integer overflow in the ff_ivi_init_planes function in
| libavcodec/ivi.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x
| through 2.8.2 allows remote attackers to cause a denial of service
| (out-of-bounds heap-memory access) or possibly have unspecified other
| impact via crafted image dimensions in Indeo Video Interactive data.

CVE-2015-8365[2]:
| The smka_decode_frame function in libavcodec/smacker.c in FFmpeg
| before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not
| verify that the data size is consistent with the number of channels,
| which allows remote attackers to cause a denial of service
| (out-of-bounds array access) or possibly have unspecified other impact
| via crafted Smacker data.

If you fix the vulnerabilities please also make sure to include the
