ffmpeg was updated to 2.8.11, containing a number of upstream improvements and fixes.

This update introduces lame and twolame. For ffmpeg2 it updates to version 2.8.13 and fixes several issues.

These security issues were fixed :

  - CVE-2017-14058: The read_data function in     libavformat/hls.c did not restrict reload attempts for     an insufficient list, which allowed remote attackers to     cause a denial of service (infinite loop) (bsc#1056762).

  - CVE-2017-14057: In asf_read_marker() due to lack of an     EOF (End of File) check might have caused huge CPU and     memory consumption. When a crafted ASF file, which     claims a large 'name_len' or 'count' field in the header     but did not contain sufficient backing data, was     provided, the loops over the name and markers would     consume huge CPU and memory resources, since there is no     EOF check inside these loops (bsc#1056761).

  - CVE-2017-14059: A DoS in cine_read_header() due to lack     of an EOF check might have caused huge CPU and memory     consumption. When a crafted CINE file, which claims a     large 'duration' field in the header but did not contain     sufficient backing data, was provided, the image-offset     parsing loop would consume huge CPU and memory     resources, since there is no EOF check inside the loop     (bsc#1056763).

  - CVE-2017-14056: A DoS in rl2_read_header() due to lack     of an EOF (End of File) check might have caused huge CPU     and memory consumption. When a crafted RL2 file, which     claims a large 'frame_count' field in the header but did     not contain sufficient backing data, was provided, the     loops (for offset and size tables) would consume huge     CPU and memory resources, since there is no EOF check     inside these loops (bsc#1056760).

  - CVE-2017-14055: a DoS in mv_read_header() due to lack of     an EOF (End of File) check might have caused huge CPU     and memory consumption. When a crafted MV file, which     claims a large 'nb_frames' field in the header but did     not contain sufficient backing data, was provided, the     loop over the frames would consume huge CPU and memory     resources, since there is no EOF check inside the loop     (bsc#1056766).

  - boo#1046211: Lots of integer overflow fixes

  - CVE-2016-9561: The che_configure function in     libavcodec/aacdec_template.c in FFmpeg allowed remote     attackers to cause a denial of service (allocation of     huge memory, and being killed by the OS) via a crafted     MOV file (boo#1015120)

  - CVE-2017-7863: FFmpeg had an out-of-bounds write caused     by a heap-based buffer overflow related to the     decode_frame_common function in libavcodec/pngdec.c     (boo#1034179)

  - CVE-2017-7865: FFmpeg had an out-of-bounds write caused     by a heap-based buffer overflow related to the     ipvideo_decode_block_opcode_0xA function in     libavcodec/interplayvideo.c and the     avcodec_align_dimensions2 function in libavcodec/utils.c     (boo#1034177)

  - CVE-2017-7866: FFmpeg had an out-of-bounds write caused     by a stack-based buffer overflow related to the     decode_zbuf function in libavcodec/pngdec.c     (boo#1034176)

  - CVE-2016-10190: Heap-based buffer overflow in     libavformat/http.c in FFmpeg allowed remote web servers     to execute arbitrary code via a negative chunk size in     an HTTP response (boo#1022920)

  - CVE-2016-10191: Heap-based buffer overflow in     libavformat/rtmppkt.c in FFmpeg allowed remote attackers     to execute arbitrary code by leveraging failure to check     for RTMP packet size mismatches (boo#1022921)

  - CVE-2016-10192: Heap-based buffer overflow in ffserver.c     in FFmpeg allowed remote attackers to execute arbitrary     code by leveraging failure to check chunk size     (boo#1022922)

  - CVE-2017-14169: In the mxf_read_primer_pack function an     integer signedness error have might occured when a     crafted file, which claims a large 'item_num' field such     as 0xffffffff, was provided. As a result, the variable     'item_num' turns negative, bypassing the check for a     large value (bsc#1057536).

  - CVE-2017-14170: Prevent DoS in     mxf_read_index_entry_array() due to lack of an EOF (End     of File) check that might have caused huge CPU     consumption. When a crafted MXF file, which claims a     large 'nb_index_entries' field in the header but did not     contain sufficient backing data, was provided, the loop     would consume huge CPU resources, since there was no EOF     check inside the loop. Moreover, this big loop can be     invoked multiple times if there is more than one     applicable data segment in the crafted MXF file     (bsc#1057537).

  - CVE-2017-14171: Prevent DoS in nsv_parse_NSVf_header()     due to lack of an EOF (End of File) check taht might     have caused huge CPU consumption. When a crafted NSV     file, which claims a large 'table_entries_used' field in     the header but did not contain sufficient backing data,     was provided, the loop over 'table_entries_used' would     consume huge CPU resources, since there was no EOF check     inside the loop (bsc#1057539).

  - CVE-2017-14223: Prevent DoS in asf_build_simple_index()     due to lack of an EOF (End of File) check that might     have caused huge CPU consumption. When a crafted ASF     file, which claims a large 'ict' field in the header but     did not contain sufficient backing data, was provided,     the for loop would consume huge CPU and memory     resources, since there was no EOF check inside the loop     (bsc#1058019)

  - CVE-2017-14222: Prevent DoS in read_tfra() due to lack     of an EOF (End of File) check that might have caused     huge CPU and memory consumption. When a crafted MOV     file, which claims a large 'item_count' field in the     header but did not contain sufficient backing data, was     provided, the loop would consume huge CPU and memory     resources, since there was no EOF check inside the loop     (bsc#1058020)

These non-security issues were fixed :

  - Unconditionalize celt, ass, openjpeg, webp, libva,     vdpau.

  - Build unconditionally with lame and twolame

  - Enable AC3 and MP3 decoding to match     multimedia:libs/ffmpeg (3.x)

For ffmpeg it updates to version 3.3.4 and fixes several issues.
