Security update for lame

This update for lame fixes the following issues:

Lame was updated to version 3.100:

  • Improved detection of MPEG audio data in RIFF WAVE files. sf#3545112 Invalid sampling detection
  • New switch --gain <decibel>, range -20.0 to +12.0, a more convenient way to apply Gain adjustment in decibels, than the use of --scale <factor>.
  • Fix for sf#3558466 Bug in path handling
  • Fix for sf#3567844 problem with Tag genre
  • Fix for sf#3565659 no progress indication with pipe input
  • Fix for sf#3544957 scale (empty) silent encode without warning

  • Fix for sf#3608583 input file name displayed with wrong character encoding (on windows console with CP_UTF8)
  • Fix dereference NULL and Buffer not NULL terminated issues. (CVE-2017-15019 bsc#1082317 CVE-2017-13712 bsc#1082399 CVE-2015-9100 bsc#1082401)
  • Fix dereference of a null pointer possible in loop.
  • Make sure functions with SSE instructions maintain their own properly aligned stack. Thanks to Fabian Greffrath
  • Multiple Stack and Heap Corruptions from Malicious File. (CVE-2017-9872 bsc#1082391 CVE-2017-9871 bsc#1082392 CVE-2017-9870 bsc#1082393 CVE-2017-9869 bsc#1082395 CVE-2017-9411 bsc#1082397 CVE-2015-9101 bsc#1082400)
  • CVE-2017-11720: Fix a division by zero vulnerability. (bsc#1082311)
  • CVE-2017-9410: Fix fill_buffer_resample function in libmp3lame/util.c heap-based buffer over-read and ap (bsc#1082333)

  • CVE-2017-9412: FIx unpack_read_samples function in frontend/get_audio.c invalid memory read and application crash (bsc#1082340)
  • Fix clip detect scale suggestion unaware of scale input value
  • HIP decoder bug fixed: decoding mixed blocks of lower sample frequency Layer3 data resulted in internal buffer overflow.
  • Add lame_encode_buffer_interleaved_int()
