CVE-2020-14163: Improper Restriction of Operations within the Bounds of a Memory Buffer

June 15, 2020 (updated July 21, 2021)

An issue was discovered in ecma/operations/ecma-container-object.c in JerryScript. Operations with key/value pairs did not consider the case where garbage collection is triggered after the key operation but before the value operation, as demonstrated by improper read access to memory in ecma_gc_set_object_visited in ecma/base/ecma-gc.c.
