Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Mitsumasa Kondo and Kyotaro Horiguchi discovered that PostgreSQL
incorrectly handled certain connection requests containing database
names starting with a dash. A remote attacker could use this flaw to
damage or destroy files within a server's data directory. This issue
only applied to Ubuntu 11.10, Ubuntu 12.04 LTS, and Ubuntu 12.10.
(CVE-2013-1899)

Marko Kreen discovered that PostgreSQL incorrectly generated random
numbers. An authenticated attacker could use this flaw to possibly
guess another database user's random numbers. (CVE-2013-1900)

Noah Misch discovered that PostgreSQL incorrectly handled certain
privilege checks. An unprivileged attacker could use this flaw to
possibly interfere with in-progress backups. This issue only applied
to Ubuntu 11.10, Ubuntu 12.04 LTS, and Ubuntu 12.10. (CVE-2013-1901).

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 postgresql-8.3, postgresql-8.4 and / or
postgresql-9.1 packages.
