* vms-alpha.c (_bfd_vms_slurp_eisd): Don't overflow when checking
offset. Don't overflow when checking rec_size, and do allow
rec_size to the end of the buffer. Ensure eisd->type can be
accessed, not just the first 32 bytes. Don't call
_bfd_vms_save_counted_string with zero length remaining. Fail
on empty string section name.
(_bfd_vms_slurp_egsd): Formatting. Catch more reads past end
of record size. Correct remaining length calculation. Fail
on empty string section name. Consolidate error paths.
2019-12-30 Alan Modra <[email protected]>
* vms-alpha.c (alpha_vms_free_private): New function, extracted..
(vms_close_and_cleanup): ..from here.
(alpha_vms_object_p): Call alpha_vms_free_private on failure.

large allocations that overflow bfd_size_type. Use just one
bfd_release on error exit.
(_bfd_slurp_extended_name_table): Use bfd_alloc for extended_names,
clear last byte rather than the entire array. Use bfd_alloc for
string table. Rearrange and simplify code copying file names.

PR 15350
* bfd.c (bfd_update_compression_header): Write zlib header for
formats other than ELF too.
2019-12-26 Alan Modra <[email protected]>
* som.c (setup_sections): Don't overflow space_strings_size. Use
bfd_malloc2 to catch overflow of size calculation.
(som_prep_for_fixups): Use bfd_zalloc2 to catch overflow of size
calculation.
(som_build_and_write_symbol_table): Similarly use bfd_zmalloc2.
(som_slurp_symbol_table): Similarly use bfd_zmalloc2, bfd_malloc2,
and bfd_zalloc2.
(bfd_som_attach_aux_hdr): Use size_t vars for string length.
(som_bfd_count_ar_symbols): Use bfd_malloc2 to catch overflow of
size calculation. Use size_t vars for length and catch overflow.
(som_slurp_armap): Use bfd_alloc2 to catch overflow of size
calculation.
(som_bfd_ar_write_symbol_stuff): Similarly use bfd_zmalloc2 and
bfd_malloc2. Perform size calculations in bfd_size_type.
2019-12-26 Hannes Domani <[email protected]>
* peicode.h (pe_bfd_read_buildid): Free data.
2019-12-23 Alan Modra <[email protected]>
* vms-alpha.c (add_symbol): Add "max" parameter. Error on string
length larger than max.
(_bfd_vms_slurp_egsd): Ensure record is at least large enough to
read string length byte, error if not. Pass size to add_symbol.
(_bfd_vms_slurp_etir): Don't read past end of buffer when reading
type and length. Allow read of last byte in buffer.
2019-12-23 Alan Modra <[email protected]>
* wasm-module.c (wasm_read_leb128): Don't allow oversize shifts.
Catch value overflow. Sign extend only on terminating byte.
2019-12-20 Alan Modra <[email protected]>
* xtensa-isa.c (xtensa_insnbuf_from_chars): Avoid signed overflow.
2019-12-20 Alan Modra <[email protected]>
* libhppa.h (hppa_field_adjust, bfd_hppa_insn2fmt): Delete forward
declaration. Move ATTRIBUTE_UNUSED to definition.

(re_assemble_3, re_assemble_12, re_assemble_14, re_assemble_16),
(re_assemble_17, re_assemble_21, re_assemble_22): Likewise. Make
args and return value unsigned. Use unsigned variables.

not returning matching target strings.
