GENTOO LINUX SECURITY ANNOUNCEMENT 200303-14

"This issue has been adressed in 3.23.56 (release build is started
today), and some steps were taken to alleviate the threat.

In particular, MySQL will no longer read config files that are
world-writeable (and SELECT ... OUTFILE always creates world-writeable
files). Also, unlike other options, for --user option the first one will
have the precedence. So if --user is set in /etc/my.cnf (as it is
recommended in the manual), datadir/my.cnf will not be able to override
it."

SOLUTION

dev-db/mysql upgrade to mysql-3.23.56 as follows:

emerge sync
emerge mysql
emerge clean
