2014-11-11Avoid coff OOMAlan Modra3-31/+44
bfd_zalloc/bfd_zmalloc to fix uninitialized memory reads is too big a hammer, when the size allocated depends on user input. A typical bfd_alloc, bfd_seek, bfd_bread sequence will give an error or warning at the point the file read fails when some enormous item as described by headers is not actually present in the file. Nice operating system allow memory overcommit. But not if you write to the memory. So bfd_zalloc can cause an OOM, thrashing, or system hangs. The patch also fixes a recently introduced endless loop on bad input. PR binutils/17512 * coffcode.h (coff_slurp_line_table): Don't bfd_zalloc, just memset the particular bits we need.
