Here's the fix I wanted to propose:

diff --git a/builtin-pack-objects.c b/builtin-pack-objects.c
index c72e07a..85c6e6e 100644
--- a/builtin-pack-objects.c
+++ b/builtin-pack-objects.c
@@ -1786,11 +1786,13 @@ int cmd_pack_objects(int argc, const char **argv, const char *prefix)
 		if (rename(pack_tmp_name, tmpname))
 			die("unable to rename temporary pack file: %s",
 			    strerror(errno));
+		chmod(tmpname, 0444);
 		snprintf(tmpname, sizeof(tmpname), "%s-%s.idx",
 			 base_name, sha1_to_hex(object_list_sha1));

 	}
 	if (progress)
