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

<p>
|
|
PostgreSQL is an open source object-relational database management
|
|
system.

|
|
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.

<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.
|
|

|
|
<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 "dev-db/postgresql"</code>
|
|
</resolution>
