  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • avformat/matroskadec : Fix use-after-free when demuxing ProRes

    avformat/matroskadec : Fix use-after-free when demuxing ProRes

    ProRes in Matroska is supposed to not contain the first atom header
    
(containing a size field and the tag "icpf") and therefore the Matroska
    
demuxer has to recreate it ; this involves an allocation and copy, of
    
course. Whether the old buffer (containing the data without the atom
    
header) needs to be freed or not depends upon whether it is what was
    
directly read (in which case it is owned by an AVBuffer) or whether it
    
has been allocated when reversing the track's content compression (e.g.
    
zlib compression) that Matroska supports.
    

    So there are three pointers involved : The one pointing to the directly
    
read data (owned by the AVBuffer), the one pointing to the currently
    
valid data (which coincides with the former if no content compression
    
needed to be reverted) and the one pointing to the new data with the
    
first atom header. The check for whether to free the second of these is
    
simply whether the first two are different.
    

    This works mostly, but there is a complication : Some muxers don't strip
    
the first atom header away and in this case, it is also not reinserted
    
and no new buffer is allocated ; instead, the second and the third
    
pointers agree. In this case, one must never free the second buffer.
    
Yet it is currently done if the track is e.g. zlib compressed.
    
This commit fixes this.
    

    This is a regression since b8e75a2a.
