Bug fixes¶
The fixes ported to 8.0 are the following:
Bug#39116965: During connection setup, connection attribute parsing could read a length-encoded size field before verifying that the complete field was present in the packet, leading to an out-of-bounds read. A size check is now performed before reading the field.
Bug#39204635: An unauthenticated repeated X Protocol TLS upgrade causes an unplanned exit of the MySQL Router.
