Synopsis
The remote database server is affected by multiple vulnerabilities.
Description
The version of MySQL Community Server installed on the remote host is earlier than 5.1.51 and is, therefore, potentially affected by multiple vulnerabilities:
- A privilege escalation vulnerability exists when using statement-based replication. Version specific comments used on a master server with a lesser release version than its slave can allow the MySQL privilege system on the slave server to be subverted. (49124)
- An authenticated user can crash the MySQL server by passing improper WKB to the 'PolyFromWKB()' function.
(51875)
- The improper handling of type errors during argument evaluation in extreme-value functions, e.g., 'LEAST()' or 'GREATEST()' caused server crashes. (55826)
- The creation of derived tables needing a temporary grouping table caused server crashes. (55568)
- The re-evaluation of a user-variable assignment expression after the creation of a temporary table caused server crashes. (55564)
- The 'convert_tz()' function can be used to crash the server by setting the timezone argument to an empty SET column value. (55424)
- The pre-evaluation of 'LIKE' predicates while preparing a view caused server crashes. (54568)
- The use of 'GROUP_CONCAT()' and 'WITH ROLLUP' caused server crashes. (54476)
- The use of an intermediate temporary table and queries containing calls to 'GREATEST()' or 'LEAST()', having a list of both numeric and 'LONGBLOB' arguments, caused server crashes. (54461)
- The use of nested joins in prepared statements or stored procedures could result in infinite loops.

Solution
Upgrade to MySQL Community Server 5.1.51 or later.
