Subject: CVE Request -- MySQL v5.1.49 -- multiple DoS flaws

Hi Steve, vendors,

   MySQL upstream yet on 2010-07-09 released version v5.1.49 of their Community Server,
addressing couple of denial of service flaws (crashes and assertion failures):
[1] http://dev.mysql.com/doc/refman/5.1/en/news-5-1-49.html

1, Security Fix: After changing the values of the innodb_file_format or
                  innodb_file_per_table configuration parameters, DDL statements
                  could cause a server crash. (Bug#55039)
    References:   http://bugs.mysql.com/bug.php?id=55039
                  https://bugzilla.redhat.com/show_bug.cgi?id=628660
    Reason:       Assertion failure leading to server abort.

2, Security Fix: Joins involving a table with a unique SET column could cause
                  a server crash. (Bug#54575)
    References:   http://bugs.mysql.com/bug.php?id=54575
                  https://bugzilla.redhat.com/show_bug.cgi?id=628040
    Reason:       NULL pointer dereference leading to (temporary) server DoS.

3, Security Fix: Incorrect handling of NULL arguments could lead to a crash
                  for IN() or CASE operations when NULL arguments were either
                  passed explicitly as arguments (for IN()) or implicitly
                  generated by the WITH ROLLUP  modifier (for IN() and CASE).
                  (Bug#54477)
    References:   http://bugs.mysql.com/bug.php?id=54477
                  https://bugzilla.redhat.com/show_bug.cgi?id=628172
    Reason:       NULL pointer dereference leading to (temporary) server DoS.

4, Security Fix: A malformed argument to the BINLOG statement could result
                  in Valgrind warnings or a server crash. (Bug#54393)
    References:   http://bugs.mysql.com/bug.php?id=54393
                  https://bugzilla.redhat.com/show_bug.cgi?id=628062
    Reason:       Use of unassigned memory leading to (temporary) server DoS (crash).

5, Security Fix: Use of TEMPORARY  InnoDB tables with nullable columns could cause
                  a server crash. (Bug#54044)
    References:   http://bugs.mysql.com/bug.php?id=54044
                  https://bugzilla.redhat.com/show_bug.cgi?id=628192
    Reason:       Assertion failure leading to server abort.

6, Security Fix: The server could crash if there were alternate reads from
                  two indexes on a table using the HANDLER interface. (Bug#54007)
    References:   http://bugs.mysql.com/bug.php?id=54007
                  https://bugzilla.redhat.com/show_bug.cgi?id=628680
    Reason:       Assertion failure leading to server abort.

7, Security Fix: Using EXPLAIN with queries of the form SELECT ... UNION
                  ... ORDER BY (SELECT ... WHERE ...) could cause a server
                  crash. (Bug#52711)
    References:   http://bugs.mysql.com/bug.php?id=52711
                  https://bugzilla.redhat.com/show_bug.cgi?id=628328
    Reason:       NULL pointer dereference leading to (temporary) server DoS.

8, Security Fix: LOAD DATA INFILE did not check for SQL errors and sent an
                  OK packet even when errors were already reported. Also, an
                  assert related to client-server protocol checking in debug
                  servers sometimes was raised when it should not have been.
                  (Bug#52512)
    References:   http://bugs.mysql.com/bug.php?id=52512
                  https://bugzilla.redhat.com/show_bug.cgi?id=628698
    Reason:       Assertion failure leading to server abort.


It does not seem, CVE identifiers have been requested / assigned to these issues
yet (either went unnoticed or not serious enough the get separate CVE ids
[as it is possible on many distributions the majority of them would mean only
temporary denial of service]).

Steve, if 'went unnoticed' is the case, could you please assign CVE identifiers
for these?

P.S.: There is one crash due OOM killer issue yet:
       [3] http://bugs.mysql.com/bug.php?id=42064
       but that one is not something we would consider as being of a security issue.
