+  <title>PostgreSQL: Multiple vulnerabilities</title>
+  <synopsis>
+    PostgreSQL contains multiple vulnerabilities that could result in privilege
+    escalation or a Denial of Service.

+  <background>
+    <p>
+    PostgreSQL is an open source object-relational database management
+    system.
+    </p>
+  </background>
+  <description>
+    <p>
+    If using the "expression indexes" feature, PostgreSQL executes index
+    functions as the superuser during VACUUM and ANALYZE instead of the
+    table owner, and allows SET ROLE and SET SESSION AUTHORIZATION in the
+    index functions (CVE-2007-6600). Additionally, several errors involving
+    regular expressions were found (CVE-2007-4769, CVE-2007-4772,
+    CVE-2007-6067). Eventually, a privilege escalation vulnerability via
+    unspecified vectors in the DBLink module was reported (CVE-2007-6601).
+    This vulnerability is exploitable when local trust or ident
+    authentication is used, and is due to an incomplete fix of
+    CVE-2007-3278.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    A remote authenticated attacker could send specially crafted queries
+    containing complex regular expressions to the server that could result
+    in a Denial of Service by a server crash (CVE-2007-4769), an infinite
+    loop (CVE-2007-4772) or a memory exhaustion (CVE-2007-6067). The two
+    other vulnerabilities can be exploited to gain additional privileges.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround for all these issues at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All PostgreSQL users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;dev-db/postgresql&quot;</code>
