CVE-2017-9250

The lexer_process_char_literal function in jerry-core/parser/js/js-lexer.c in JerryScript 1.0 does not skip memory allocation for empty strings, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via malformed JavaScript source code, related to the jmem_heap_free_block function.
