There is an Assertion 'ecma_is_lexical_environment (object_p)' failed at /base/ecma-helpers.c(ecma_get_lex_env_type) in JerryScript 3.0.0.

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.

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.

An issue was discovered in JerryScript commit a6ab5e9. There is an Use-After-Free in lexer_compare_identifier_to_string in js-lexer.c file.

JerryScript 2.2.0 allows attackers to cause a denial of service (stack consumption) via a proxy operation.

parser/js/js-scanner.c in JerryScript 2.2.0 mishandles errors during certain out-of-memory conditions, as demonstrated by a scanner_reverse_info_list NULL pointer dereference and a scanner_scan_all assertion failure.

JerryScript 2.2.0 allows attackers to cause a denial of service (assertion failure) because a property key query for a Proxy object returns unintended data.

Jerryscript 3.0 (commit 05dbbd1) was discovered to contain an Assertion Failure via the ecma_property_hashmap_create at jerry-core/ecma/base/ecma-property-hashmap.c.

Jerryscript 3.0 (commit 05dbbd1) was discovered to contain an Assertion Failure via the parser_parse_for_statement_start at jerry-core/parser/js/js-parser-statm.c.
