The fact that they have not issued any security update for MySQL 5.0 since mid 2013 .. and since then there have been 4 security issues fixed in EL5 (1 Important, 3 Moderate) in the mysql55 updates. > And is the same true for C6, which comes with mysql 5.1, that one should > use mysql55 from SCL instead?
