Jerryscript v2.4.0 was discovered to contain a stack buffer overflow via the function jerryx_print_unhandled_exception in /util/print.c.
There is a heap-use-after-free at ecma-helpers-string.c:1940 in ecma_compare_ecma_non_direct_strings in JerryScript 2.4.0
There is a stack-overflow at ecma-helpers.c:326 in ecma_get_lex_env_type in JerryScript 2.4.0
A buffer overflow in ecma_builtin_typedarray_prototype_filter() in JerryScript version fe3a5c0 allows an attacker to construct a fake object or a fake arraybuffer with unlimited size.
JerryScript Git version 14ff5bf does not sufficiently track and release allocated memory via jerry-core/ecma/operations/ecma-regexp-object.c after RegExp, which causes a memory leak.
A Heap-based Buffer Overflow vulnerability exists in JerryScript 2.4.0 and prior versions via an out-of-bounds read in parser_parse_for_statement_start in the js-parser-statm.c file. This issue is similar to CVE-2020-29657.
