The following two security updates has been released for Debian GNU/Linux:

[DLA-152-1] postgresql-8.4 update
[DSA 3161-1] dbus security update

[DLA-152-1] postgresql-8.4 update

Package : postgresql-8.4
Version : 8.4.22lts1-0+deb6u1
CVE ID : CVE-2014-8161 CVE-2015-0241 CVE-2015-0243 CVE-2015-0244

Several vulnerabilities were discovered in PostgreSQL, a relational
database server system. The 8.4 branch is EOLed upstream, but still
present in Debian squeeze. This new LTS minor version contains the
fixes that were applied upstream to the 9.0.19 version, backported to
8.4.22 which was the last version officially released by the PostgreSQL
developers. This LTS effort for squeeze-lts is a community project
sponsored by credativ GmbH.

CVE-2014-8161: Information leak
A user with limited clearance on a table might have access to information
in columns without SELECT rights on through server error messages.

CVE-2015-0241: Out of boundaries read/write
The function to_char() might read/write past the end of a buffer. This
might crash the server when a formatting template is processed.

CVE-2015-0243: Buffer overruns in contrib/pgcrypto
The pgcrypto module is vulnerable to stack buffer overrun that might
crash the server.

CVE-2015-0244: SQL command injection
Emil Lenngren reported that an attacker can inject SQL commands when the
synchronization between client and server is lost.

[DSA 3161-1] dbus security update

Debian Security Advisory DSA-3161-1 security@debian.org

- -------------------------------------------------------------------------

Package : dbus
CVE ID : CVE-2015-0245
Debian Bug : 777545

Simon McVittie discovered a local denial of service flaw in dbus, an
asynchronous inter-process communication system. On systems with
systemd-style service activation, dbus-daemon does not prevent forged
ActivationFailure messages from non-root processes. A malicious local
user could use this flaw to trick dbus-daemon into thinking that systemd
failed to activate a system service, resulting in an error reply back to
the requester.

For the stable distribution (wheezy), this problem has been fixed in
version 1.6.8-1+deb7u6.

For the unstable distribution (sid), this problem has been fixed in
version 1.8.16-1.

We recommend that you upgrade your dbus packages.
