  • avcodec/tiff : Restrict tag order based on specification

    avcodec/tiff : Restrict tag order based on specification

    "The entries in an IFD must be sorted in ascending order by Tag. Note that this is
    
 not the order in which the fields are described in this document."
    

    This way various dimensions, sample and bit sizes cannot be changed at
    
arbitrary times which reduces the potential for bugs.
    
The tag reading code also on various places assumes that numerically previous
    
tags have already been parsed, so this needs to be enforced one way or another.
    

    If this commit causes problems with real world files which are not easy to fix
    
then some other form of checks are needed to ensure the various dependencies
    
in the tag reading are not violated.
    

    Fixes : out of array access

  • random_seed : Rewrite the generic clock() based seed code

    random_seed : Rewrite the generic clock() based seed code

    The new code is faster and reuses the previous state in case of
    
multiple calls.
    

    The previous code could easily end up in near-infinite loops,
    
if the difference between two clock() calls never was larger than
    
1.
    

    This makes fate-parseutils finish in finite time when run in wine,
    
if CryptGenRandom isn’t available (which e.g. isn’t available if
    
targeting Windows RT/metro).
    

    Patch originally by Michael Niedermayer but with some modifications
    
by Martin Storsjö.
