From 3bba9d93294a8172018731477df72c1c3ef42136 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 4 Jan 2023 21:46:06 +1030 Subject: [PATCH] fuzzed file timeout objcopy of archive, element containing an object with a fuzzed section size far exceeding the element size. copy_section detects this, but the temp file is laid out for the large section. It can take a long time to write terabytes of sparse file, a waste of time when it will be deleted. * objcopy.c (copy_archive): Don't write element contents after bad status result from copy_object. --- binutils/objcopy.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/binutils/objcopy.c b/binutils/objcopy.c index a6182b48b6c..4d888906e67 100644 --- a/binutils/objcopy.c +++ b/binutils/objcopy.c @@ -3686,7 +3686,8 @@ copy_archive (bfd *ibfd, bfd *obfd, const char *output_target, if (!ok_object) del = !copy_unknown_object (this_element, output_bfd); - if (!(ok_object && !del ? bfd_close : bfd_close_all_done) (output_bfd)) + if (!(ok_object && !del && !status + ? bfd_close : bfd_close_all_done) (output_bfd)) { bfd_nonfatal_message (output_name, NULL, NULL, NULL); /* Error in new object file.
