Buffer overflow vulnerability in file ecma-builtin-array-prototype.c:909 in function ecma_builtin_array_prototype_object_slice in Jerryscript before commit e1ce7dd7271288be8c0c8136eea9107df73a8ce2 on Oct 20, 2021.

There is a stack-overflow at ecma-helpers.c:326 in ecma_get_lex_env_type in JerryScript 2.4.0

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

An issue was discovered in JerryScript 2.4.0. There is a heap-use-after-free in ecma_bytecode_ref in ecma-helpers.c file.

An issue was discovered in JerryScript 2.4.0. There is a SEVG in ecma_deref_bigint in ecma-helpers.c file.

An issue was discovered in JerryScript 2.4.0. There is a SEGV in main_print_unhandled_exception in main-utils.c file.

An issue was discovered in JerryScript 2.4.0. There is a heap-buffer-overflow in lexer_parse_number in js-lexer.c file.

An issue was discovered in JerryScript 2.4.0. There is a heap-use-after-free in ecma_is_lexical_environment in the ecma-helpers.c file.

In JerryScript 2.3.0, there is an out-of-bounds read in main_print_unhandled_exception in the main-utils.c file.

JerryScript through 2.3.0 allows stack consumption via function a(){new new Proxy(a,{})}JSON.parse("[]",a). NOTE: the vendor states that the problem is the lack of the --stack-limit option

JerryScript through 2.3.0 has a (function({a=arguments}){const arguments}) buffer over-read.

An issue was discovered in ecma-helpers.c in jerryscript version 2.3.0, allows local attackers to cause a denial of service (DoS) (Null Pointer Dereference).
