Subject: [PATCH] elf: Don't match corrupt section header in linker input
|
||||
|
||||
Don't swap in nor match corrupt section header in linker input to avoid
|
||||
linker crash later.
|
||||
|
||||
PR ld/33457
|
||||
* elfcode.h (elf_swap_shdr_in): Changed to return bool. Return
|
||||
false for corrupt section header in linker input.
|
||||
(elf_object_p): Reject if elf_swap_shdr_in returns false.

||||
