Synopsis:	Moderate: postgresql security update
Issue date:	2010-05-19
CVE Names:	CVE-2009-4136 CVE-2010-0442 CVE-2010-0733
 CVE-2010-1169 CVE-2010-1170

PostgreSQL is an advanced object-relational database management system
(DBMS). PL/Perl and PL/Tcl allow users to write PostgreSQL functions in
the Perl and Tcl languages, and are installed in trusted mode by
default. In trusted mode, certain operations, such as operating system
level access, are restricted.

A flaw was found in the way PostgreSQL enforced permission checks on
scripts written in PL/Perl. If the PL/Perl procedural language was
registered on a particular database, an authenticated database user
running a specially-crafted PL/Perl script could use this flaw to bypass
intended PL/Perl trusted mode restrictions, allowing them to run
arbitrary Perl scripts with the privileges of the database server.
(CVE-2010-1169)

A flaw was found in the way PostgreSQL enforced permission checks on
scripts written in PL/Tcl. If the PL/Tcl procedural language was
registered on a particular database, an authenticated database user
running a specially-crafted PL/Tcl script could use this flaw to bypass
intended PL/Tcl trusted mode restrictions, allowing them to run
arbitrary Tcl scripts with the privileges of the database server.
(CVE-2010-1170)

A buffer overflow flaw was found in the way PostgreSQL retrieved a
substring from the bit string for BIT() and BIT VARYING() SQL data
types. An authenticated database user running a specially-crafted SQL
query could use this flaw to cause a temporary denial of service
(postgres daemon crash) or, potentially, execute arbitrary code with the
privileges of the database server. (CVE-2010-0442)

An integer overflow flaw was found in the way PostgreSQL used to
calculate the size of the hash table for joined relations. An
authenticated database user could create a specially-crafted SQL query
which could cause a temporary denial of service (postgres daemon crash)
or, potentially, execute arbitrary code with the privileges of the
database server. (CVE-2010-0733)

PostgreSQL improperly protected session-local state during the execution
of an index function by a database superuser during the database
maintenance operations. An authenticated database user could use this
flaw to elevate their privileges via specially-crafted index functions.
(CVE-2009-4136)

If the postgresql service is running, it will be automatically restarted
after installing this update.
