USN-1378-1: PostgreSQL vulnerabilities

28 February 2012

Several security issues were fixed in PostgreSQL.




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.

Update instructions

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

Ubuntu 8.04
Ubuntu 11.10
Ubuntu 11.04
Ubuntu 10.10
Ubuntu 10.04

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

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