Debian DSA-2418-1 Critical: PostgreSQL Local Security Issues

Several local vulnerabilities have been discovered in PostgreSQL, an
object-relational SQL database. The Common Vulnerabilities and Exposures
project identifies the following problems:

CVE-2012-0866

It was discovered that the permissions of a function called by a
trigger are not checked. This could result in privilege escalation.

CVE-2012-0867

It was discovered that only the first 32 characters of a host name
are checked when validating host names through SSL certificates.
This could result in spoofing the connection in limited
circumstances.

CVE-2012-0868

It was discovered that pg_dump did not sanitise object names.
This could result in arbitrary SQL command execution if a
malformed dump file is opened.

For the stable distribution (squeeze), this problem has been fixed in
version 8.4.11-0squeeze1.

For the unstable distribution (sid), this problem has been fixed in
version 8.4.11-1.

We recommend that you upgrade your postgresql-8.4 packages.
