Ubuntu Security Notice (C) 2009-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

It was discovered that PostgreSQL could be made to unload and reload
an already loaded module by using the LOAD command. A remote
authenticated attacker could exploit this to cause a denial of
service. This issue did not affect Ubuntu 6.06 LTS. (CVE-2009-3229)

Due to an incomplete fix for CVE-2007-6600, RESET ROLE and RESET
SESSION AUTHORIZATION operations were allowed inside security-definer
functions. A remote authenticated attacker could exploit this to
escalate privileges within PostgreSQL. (CVE-2009-3230)

It was discovered that PostgreSQL did not properly perform LDAP
authentication under certain circumstances. When configured to use
LDAP with anonymous binds, a remote attacker could bypass
authentication by supplying an empty password. This issue did not
affect Ubuntu 6.06 LTS. (CVE-2009-3231).

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 6.8

CVSS Temporal Score : 5.0
(CVSS2#E:U/RL:OF/RC:C)
