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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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-2015-8364)

Note that Nessus relies on the presence of the package as reported by the vendor.

It was discovered that Libav incorrectly handled certain malformed media files. If a user were tricked into opening a crafted media file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update to ffmpeg 2.8.3 fixes the following security issues :

  - CVE-2015-8363: Check for duplicate SIZ marker /     asan_heap-oob [boo#957114]

  - CVE-2015-8364: Check image dimensions / integer overflow     [boo#957115]

  - CVE-2015-8365: out of array access / asan_heap-oob     [boo#957116]

NVD reports :

The update_dimensions function in libavcodec/vp8.c in FFmpeg through 2.8.1, as used in Google Chrome before 46.0.2490.71 and other products, relies on a coefficient-partition count during multi-threaded operation, which allows remote attackers to cause a denial of service (race condition and memory corruption) or possibly have unspecified other impact via a crafted WebM file.

The ljpeg_decode_yuv_scan function in libavcodec/mjpegdec.c in FFmpeg before 2.8.2 omits certain width and height checks, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted MJPEG data.

The ff_hevc_parse_sps function in libavcodec/hevc_ps.c in FFmpeg before 2.8.2 does not validate the Chroma Format Indicator, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted High Efficiency Video Coding (HEVC) data.

The decode_uncompressed function in libavcodec/faxcompr.c in FFmpeg before 2.8.2 does not validate uncompressed runs, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted CCITT FAX data.

The init_tile function in libavcodec/jpeg2000dec.c in FFmpeg before 2.8.2 does not enforce minimum-value and maximum-value constraints on tile coordinates, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 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.

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.

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.
