| Description: | Description:
The remote host is missing an update to postgresql
announced via advisory USN-568-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04
Ubuntu 7.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Nico Leidecker discovered that PostgreSQL did not properly
restrict dblink functions. An authenticated user could exploit
this flaw to access arbitrary accounts and execute arbitrary
SQL queries. (CVE-2007-3278, CVE-2007-6601)
It was discovered that the TCL regular expression parser used
by PostgreSQL did not properly check its input. An attacker
could send crafted regular expressions to PostgreSQL and cause
a denial of service via resource exhaustion or database crash.
(CVE-2007-4769, CVE-2007-4772, CVE-2007-6067)
It was discovered that PostgreSQL executed VACUUM and ANALYZE
operations within index functions with superuser privileges and
also allowed SET ROLE and SET SESSION AUTHORIZATION within index
functions. A remote authenticated user could exploit these flaws
to gain privileges. (CVE-2007-6600)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
postgresql-8.1 8.1.11-0ubuntu0.6.06.1
postgresql-pltcl-8.1 8.1.11-0ubuntu0.6.06.1
Ubuntu 6.10:
postgresql-8.1 8.1.11-0ubuntu0.6.10.1
postgresql-pltcl-8.1 8.1.11-0ubuntu0.6.10.1
Ubuntu 7.04:
postgresql-8.2 8.2.6-0ubuntu0.7.04.1
postgresql-pltcl-8.2 8.2.6-0ubuntu0.7.04.1
Ubuntu 7.10:
postgresql-8.2 8.2.6-0ubuntu0.7.10.1
postgresql-pltcl-8.2 8.2.6-0ubuntu0.7.10.1
In general, a standard system upgrade is sufficient to effect the
necessary changes.
