Hi,

pg_hba.conf does not have protection for this security issue.

Regards, Devrim

Hi All

I'm trying to understand the implications of the latest security fix to
postgresql [1].

We have a setup were we in pg_hba.conf have limited the allowed IP
addresses of the clients. But does anyone know if CVE-2013-1899 allows
an arbitrary attacker to use the exploits described in [1]?

We are using PostgreSQL 8.4.

Best regards,

Mads

Yes, if you were running 9.0+. pg_hba.conf does not limit access
sufficiently, though listen_addresses does.

We are using PostgreSQL 8.4.

8.4 does not contain the bug.
