glib: buffer over-read in glib/gvariant-serialiser.c via gvs_tuple_is_normal()

A flaw was found in GLib. An off-by-one error can occur in the gvstupleisnormal function in the glib/gvariant-serialiser.c file when doing an alignment padding check because the bounds check uses instead of =, causing an out-of-bounds read of only 1 byte. This issue can cause a minor information...
