Memory leaks and ineffective bounds checking in wasm_scan

[deliverable/binutils-gdb.git] / bfd / ChangeLog

2020-01-13  Alan Modra  <amodra@gmail.com>

	* wasm-module.c (wasm_scan_name_function_section): Formatting.
	Delete asect name check.  Move asect NULL check to wasm_object_p.
	Correct bounds check of sizes against end.  Replace uses of
	bfd_zalloc with bfd_alloc, zeroing only necessary bytes.  Use
	just one bfd_release.
	(wasm_scan): Don't use malloc/strdup for section names,
	bfd_alloc instead.  Simplify code prefixing section name.
	Formatting.  Don't attempt to free memory here..
	(wasm_object_p): ..do so here.
