  • avformat/mov : fix overallocation when reading pssh/saiz

    avformat/mov : fix overallocation when reading pssh/saiz

    mov_try_read_block() allocates 1MB at least, which can be more than
    
enough. It was called when reading saiz box, which can appear
    
periodically inside fmp4. This consumes a lot of memory.
    

    We can fix mov_try_read_block() by clamp 'block_size' with 'size'.
    
However, the function is harmful than helpful. It avoids allocating
    
large memory when the real data is small. Even in that case, if
    
allocating large memory directly failed, it's fine to return ENOMEM ;
    
if allocating success and reading doesn't match the given size, it's
    
fine to free and return AVERROR_INVALIDDATA. In other cases, it's a
    
waste of CPU and memory.
    

    So I decided to remove the function, and replace it by call
    
av_malloc() and avio_read() directly.
    

    mov_read_saiz() and mov_read_pssh() need more check, but they don't
    
belong to this patch.
    

    Fixes #7641 and #9243.

  • avformat/apngdec : Check fcTL chunk length when reading header

    avformat/apngdec : Check fcTL chunk length when reading header

    Reading the header terminates when an fcTL chunk is encountered in which
    
case read_header returned success without checking the length of said
    
chunk. Yet when read_packet processes this chunk, it checks for the
    
length to be 26 and errors out otherwise. So do so when reading the header,
    
too.
