|---|
| विवरण | A vulnerability was found in GNU Binutils 2.47. The ld linker has an assertion failure in _bfd_elf_strtab_delref (bfd/elf-strtab.c:200) when linking malformed ELF files with --version-exports-section symbol --shared options. When processing malformed versioned symbols, the function triggers BFD_ASSERT on inconsistent string table entries causing SEGV. Reproducer: ld --version-exports-section symbol --shared -o /dev/null bug_13.o (with PoC file). Stack trace: #0 _bfd_elf_strtab_delref bfd/elf-strtab.c:200, #1 _bfd_elf_link_hash_hide_symbol bfd/elflink.c:8344, #2 _bfd_x86_elf_hide_symbol bfd/elfxx-x86.c:3659, #3 _bfd_elf_link_hide_sym_by_version bfd/elflink.c:2644, #4 _bfd_x86_elf_link_symbol_references_local bfd/elfxx-x86.c:3695. |
