The remote host is affected by the vulnerability described in GLSA-200410-22 (MySQL: Multiple vulnerabilities)
The following vulnerabilities were found and fixed in MySQL:
Oleksandr Byelkin found that ALTER TABLE ... RENAME checks CREATE/INSERT rights of the old table instead of the new one (CAN-2004-0835). Another privilege checking bug allowed users to grant rights on a database they had no rights on.
Dean Ellis found a defect where multiple threads ALTERing the MERGE tables to change the UNION could cause the server to crash (CAN-2004-0837).
Another crash was found in MATCH ... AGAINST() queries with missing closing double quote.
Finally, a buffer overrun in the mysql_real_connect function was found by Lukasz Wojtow (CAN-2004-0836).
Impact :
The privilege checking issues could be used by remote users to bypass their rights on databases. The two crashes issues could be exploited by a remote user to perform a Denial of Service attack on MySQL server. The buffer overrun issue could also be exploited as a Denial of Service attack, and may allow to execute arbitrary code with the rights of the MySQL daemon (typically, the 'mysql' user).
Workaround :
There is no known workaround at this time.
