CVE-2020-35457

** DISPUTED ** GNOME GLib before 2.65.3 has an integer overflow, that might lead
to an out-of-bounds write, in g_option_group_add_entries. NOTE: the vendor's
position is "Realistically this is not a security issue. The standard pattern is
for callers to provide a static list of option entries in a fixed number of
calls to g_option_group_add_entries()." The researcher states that this pattern
is undocumented.
