Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : postgresql-8.1, postgresql-8.3 vulnerabilities (USN-834-1)

Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.9
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
