3. Description:
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. The PostgreSQL SECURITY DEFINER parameter, which
can be used when creating a new PostgreSQL function, specifies that the
function will be executed with the privileges of the user that created it.
It was discovered that a user could utilize the features of the PL/Perl and
PL/Tcl languages to modify the behavior of a SECURITY DEFINER function
created by a different user. If the PL/Perl or PL/Tcl language was used to
implement a SECURITY DEFINER function, an authenticated database user could
use a PL/Perl or PL/Tcl script to modify the behavior of that function
during subsequent calls in the same session. This would result in the
modified or injected code also being executed with the privileges of the
user who created the SECURITY DEFINER function, possibly leading to
privilege escalation. (CVE-2010-3433)
These updated postgresql packages upgrade PostgreSQL to version 8.4.5.
Refer to the PostgreSQL Release Notes for a list of changes:
http://www.postgresql.org/docs/8.4/static/release.html
All PostgreSQL users are advised to upgrade to these updated packages,
which correct this issue. If the postgresql service is running, it will be
automatically restarted after installing this update.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
