bounds.
* elf32_getshdr.c (elfw2(LIBELFBITS,getshdr)): Fix comment pasto.
Check if section header table fits into object's bounds.
- * elf_begin.c (get_shnum): Fail if maxsize is smaller than ELF headers.
- Ensure first section header fits into object's bounds.
+ * elf_begin.c (get_shnum): Ensure section headers fits into
+ object's bounds.
(file_read_elf): Make sure scncnt is small enough to allocate both
ElfXX_Shdr and Elf_Scn array. Make sure section and program header
tables fit into object's bounds. Avoid memory leak on failure.
(check_symtab, is_rel_dyn, check_rela, check_rel, check_dynamic,
check_symtab_shndx, check_hash, check_versym): Robustify.
