Multiple vulnerabilities have been identified in MySQL, which could be exploited by malicious users to bypass security restrictions, manipulate certain data or potentially obtain elevated privileges.
The first issue is caused by an error in the "mysql_update()" [sql/sql_update.cc] function that does not properly validate user privileges when using a view, which could be exploited by a malicious user to gain UPDATE privileges on arbitrary tables.
The second vulnerability is caused by errors in the "udf_init()" and "mysql_create_function()" [sql/sql_udf.cc] functions that do not properly validate library paths, which could be exploited by malicious users to load arbitrary libraries.
The third issue is caused by an error in the handling of password packets in the connection protocol, which could be exploited by attackers to crash an affected server.
The fourth vulnerability is caused by an error in the "CREATE TABLE LIKE" command that does not require SELECT privileges on the source table, which could be exploited by attackers to bypass security restrictions.
