| 제목 | GNU Binutils 2.47 Memory Corruption |
|---|
| 설명 | A vulnerability was found in GNU Binutils 2.47. The ld linker has a NULL pointer dereference in bfd_elf_set_group_contents (bfd/elf.c:3952) when processing malformed SHT_GROUP sections in ELF object files during relocatable linking (-r option). When a corrupted group section has invalid section/element links, the function dereferences a NULL pointer causing a SEGV crash. Reproducer: ld -r -o /dev/null bug_7.o (with PoC file). Stack trace: #0 bfd_elf_set_group_contents bfd/elf.c:3952, #1 bfd_map_over_sections bfd/section.c:1369, #2 _bfd_elf_final_link bfd/elflink.c:13820, #3 ldwrite ld/ldwrite.c:548, #4 main ld/ldmain.c:1001. |
