Description of problem:

PostgreSQL released a security update that reportedly fixes a bug, that
allowed unprivileged users execute code with privilegies of SECURITY
DEFINER functions.

See URL for details.
Comment 1 Lubomir Kundrak 2007-04-25 11:30:13 EDT
Tom, as PostgreSQL is far beyond the scope of my understanding, could you
please help me determine the following:

1.) whether the flaw affects the 7.1 line, as used in RHEL2.1? I assume it
affects other supported releases, as update was released for the respective
version lines?

2.) how serious the bug is. Is this similar to #156726, where an authenticated
users user could gain superuser rights? Or is it less likely to be exploited?
I have no idea what a SECURITY DEFINER is, and in with what privileges are
those functions executed.
