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 product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
