1) Incorrect Conversion between Numeric Types (CVE-ID: CVE-2021-27218)
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to incorrect conversion between numeric types in Gnome Glib. If g_byte_array_new_take() was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2**32, causing unintended length truncation.
