An issue was discovered in JerryScript 1.0. There is a heap-based buffer over-read in the lit_read_code_unit_from_hex function via a RegExp("[\\u0") payload, related to re_parse_char_class in parser/regexp/re-parser.c.

An issue was discovered in JerryScript 1.0. There is a heap-based buffer over-read in the lit_read_code_unit_from_utf8 function via a RegExp("[\\u0020") payload, related to re_parse_char_class in parser/regexp/re-parser.c.

An issue was discovered in JerryScript 1.0. There is a heap-based buffer over-read in the lit_read_code_unit_from_hex function in lit/lit-char-helpers.c via a RegExp("[\x0"); payload.

JerryScript 1.0 allows remote attackers to cause a denial of service (jmem_heap_alloc_block_internal heap memory corruption) or possibly execute arbitrary code via a crafted .js file, because unrecognized \ characters cause incorrect 0x00 characters in bytecode.literal data.

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…
