Andreas Cadhalpun 4e4708ad80 apedec: prevent out of array writes in decode_array_0000 
s->decoded_buffer is allocated with a min_size of:
    2 * FFALIGN(blockstodecode, 8) * sizeof(*s->decoded_buffer)

Then it is assigned to s->decoded[0] (and s->decoded_buffer + FFALIGN(blockstodecode, 8)
to s->decoded[1]) and passed as out buffer to decode_array_0000.

In this function 64 elements of the out buffer are written
unconditionally and outside the array if blockstodecode is too small.

This causes memory corruption, leading to segmentation faults or other
crashes.

Thus change decode_array_0000 to write at most blockstodecode elements
of the out buffer.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analisys tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
