Ubuntu Security Notice USN-1378-1
Posted Feb 29, 2012
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1378-1 - It was discovered that PostgreSQL incorrectly checked permissions on functions called by a trigger. An attacker could attach a trigger to a table they owned and possibly escalate privileges. It was discovered that PostgreSQL incorrectly truncated SSL certificate name checks to 32 characters. If a host name was exactly 32 characters, this issue could be exploited by an attacker to spoof the SSL certificate. This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10, Ubuntu 11.04 and Ubuntu 11.10. Various other issues were also addressed.

============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

Several security issues were fixed in PostgreSQL.

Software Description:
- postgresql-9.1: Object-relational SQL database
- postgresql-8.4: Object-relational SQL database
- postgresql-8.3: Object-relational SQL database

Details:

It was discovered that PostgreSQL incorrectly checked permissions on
functions called by a trigger. An attacker could attach a trigger to a
table they owned and possibly escalate privileges. (CVE-2012-0866)

It was discovered that PostgreSQL incorrectly truncated SSL certificate
name checks to 32 characters. If a host name was exactly 32 characters,
this issue could be exploited by an attacker to spoof the SSL certificate.
This issue affected Ubuntu 10.04 LTS, Ubuntu 10.10, Ubuntu 11.04 and
Ubuntu 11.10. (CVE-2012-0867)

It was discovered that the PostgreSQL pg_dump utility incorrectly filtered
line breaks in object names. An attacker could create object names that
execute arbitrary SQL commands when a dump script is reloaded.
(CVE-2012-0868)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
postgresql-9.1 9.1.3-0ubuntu0.11.10

Ubuntu 11.04:
postgresql-8.4 8.4.11-0ubuntu0.11.04

Ubuntu 10.10:
postgresql-8.4 8.4.11-0ubuntu0.10.10

Ubuntu 10.04 LTS:
postgresql-8.4 8.4.11-0ubuntu0.10.04

Ubuntu 8.04 LTS:

In general, a standard system update will make all the necessary changes.

This update uses a new upstream release, which includes additional bug
fixes.
