2020-03-05Large memory allocation reading fuzzed 64-bit archiveAlan Modra2-1/+15
This patch adds a sanity check for the size of an armap. * archive64.c (_bfd_archive_64_bit_slurp_armap): Check parsed_size against file size before allocating memory. Use bfd_alloc rather than bfd_zalloc for carsym/strings memory.
