commit c9c1d674406c5fff9d2f2ea771e4288cb6bf4e5a
Author: Espen Grindhaug <espen@grindhaug.org>
Date:   Thu Nov 27 15:49:23 2014 +0000

    Fixes an infinite loop in readelf parsing a corrupt binary, and other minor corrections.
    
    	PR binutils/17531
    	* readelf.c (get_data): Move excessive length check to earlier on
    	in the function and allow for wraparound in the arithmetic.
    	(get_32bit_elf_symbols): Terminate early if the section size is
    	zero.  Check for an invalid sh_entsize.  Check for an index
    	section with an invalid size.
    	(get_64bit_elf_symbols): Likewise.
    	(process_section_groups): Check for an invalid sh_entsize.
