RHSA-2010:0908-01: [RHSA-2010:0908-01] postgresql: Moderate Advisory
Product: Red Hat Enterprise Linux
Summary:

Updated postgresql packages that fix one security issue are now available

for Red Hat Enterprise Linux 6.
Description:
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)
