postgresql84 security update

CentOS Errata and Security Advisory CESA-2010:0430

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)

Red Hat would like to thank Tim Bunce for responsibly reporting the
CVE-2010-1169 flaw.
