CVE-2009-4034
PostgreSQL 7.4.x before 7.4.27, 8.0.x before 8.0.23, 8.1.x before
8.1.19, 8.2.x before 8.2.15, 8.3.x before 8.3.9, and 8.4.x before
8.4.2 does not properly handle a '\0' character in a domain name in
the subject's Common Name (CN) field of an X.509 certificate, which
(1) allows man-in-the-middle attackers to spoof arbitrary SSL-based
PostgreSQL servers via a crafted server certificate issued by a
legitimate Certification Authority, and (2) allows remote attackers to
bypass intended client-hostname restrictions via a crafted client
certificate issued by a legitimate Certification Authority, a related
issue to CVE-2009-2408.

CVE-2009-4136
PostgreSQL 7.4.x before 7.4.27, 8.0.x before 8.0.23, 8.1.x before
8.1.19, 8.2.x before 8.2.15, 8.3.x before 8.3.9, and 8.4.x before
8.4.2 does not properly manage session-local state during execution of
an index function by a database superuser, which allows remote
authenticated users to gain privileges via a table with crafted index
functions, as demonstrated by functions that modify (1) search_path or
(2) a prepared statement, a related issue to CVE-2007-6600 and
CVE-2009-3230.");
