"Dmitri Lenev discovered that arguments of setuid SQL functions were
evaluated in the security context of the functions' definer instead of
its caller. An authenticated user with the privilege to call such a
function could exploit this to execute arbitrary statements with the
privileges of the definer of that function. (CVE-2006-4227)

Peter Gulutzan reported a potentially confusing situation of the MERGE
table engine. If an user creates a merge table, and the administrator
later revokes privileges on the original table only (without changing
the privileges on the merge table), that user still has access to the
data by using the merge table. This is intended behaviour, but might
be undesirable in some installations; this update introduces a new
server option '--skip-merge' which disables the MERGE engine
completely. (CVE-2006-4031).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

"MySQL did not require privileges such as 'SELECT' for the source table
in a 'CREATE TABLE LIKE' statement. An authenticated user could obtain
sensitive information, such as the table structure. (CVE-2007-3781)

A flaw was discovered in MySQL that allowed an authenticated user to
gain update privileges for a table in another database, via a view
that refers to the external table. (CVE-2007-3782)

MySQL did not require the 'DROP' privilege for 'RENAME TABLE'
statements. An authenticated user could use this flaw to rename
arbitrary tables. (CVE-2007-2691)

A flaw was discovered in the mysql_change_db function when returning
from SQL SECURITY INVOKER stored routines. An authenticated user could
use this flaw to gain database privileges. (CVE-2007-2692)

MySQL allowed an authenticated user to bypass logging mechanisms via
SQL queries that contain the NULL character, which were not properly
handled by the mysql_real_query function. (CVE-2006-0903)

MySQL allowed an authenticated user to access a table through a
previously created MERGE table, even after the user's privileges were
revoked from the original table, which might violate intended security
policy. This is addressed by allowing the MERGE storage engine to be
disabled, which can be done by running mysqld with the '--skip-merge'
option. (CVE-2006-4031)

MySQL evaluated arguments in the wrong security context, which allowed
an authenticated user to gain privileges through a routine that had
been made available using 'GRANT EXECUTE'. (CVE-2006-4227)

Multiple flaws in MySQL allowed an authenticated user to cause the
MySQL daemon to crash via crafted SQL queries. This only caused a
temporary denial of service, as the MySQL daemon is automatically
restarted after the crash. (CVE-2006-7232, CVE-2007-1420,
CVE-2007-2583)

As well, these updated packages fix the following bugs :

  - a separate counter was used for 'insert delayed'
    statements, which caused rows to be discarded. In these
    updated packages, 'insert delayed' statements no longer
    use a separate counter, which resolves this issue.

  - due to a bug in the Native POSIX Thread Library, in
    certain situations, 'flush tables' caused a deadlock on
    tables that had a read lock. The mysqld daemon had to be
    killed forcefully. Now, 'COND_refresh' has been replaced
    with 'COND_global_read_lock', which resolves this issue.

  - mysqld crashed if a query for an unsigned column type
    contained a negative value for a 'WHERE [column] NOT IN'
    subquery.

  - in master and slave server situations, specifying 'on
    duplicate key update' for 'insert' statements did not
    update slave servers.

  - in the mysql client, empty strings were displayed as
    'NULL'. For example, running 'insert into [table-name]
    values (' ');' resulted in a 'NULL' entry being
    displayed when querying the table using 'select * from
    [table-name];'.

  - a bug in the optimizer code resulted in certain queries
    executing much slower than expected.

  - on 64-bit PowerPC architectures, MySQL did not calculate
    the thread stack size correctly, which could have caused
    MySQL to crash when overly-complex queries were used.

Note: these updated packages upgrade MySQL to version 5.0.45. For a
full list of bug fixes and enhancements, refer to the MySQL release
