PR binutils/17512 * dwarf.c (read_1_byte, read_1_signed_byte, read_2_bytes) (read_4_bytes, read_8_bytes, read_n_bytes, read_string) (read_indirect_string, read_alt_indirect_string) (read_alt_indirect_ref, read_address, read_abbrevs) (read_attribute_value, read_attribute, decode_line_info) (find_abstract_instance_name, read_rangelist) (scan_unit_for_symbols, parse_comp_unit) (_bfd_dwarf2_find_nearest_line): Harden DWARF reading code. Pass end pointers to reading functions and check for offsets taking pointers out of range. Replace calls to read_*_leb128 with calls to safe_read_leb128. (* elf64-ppc.c (opd_entry_value): Add a check for an overlarge offset. * syms.c (_bfd_stab_section_find_nearest_line): Add checks for computed file_name address being before the start of the string table. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
