Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200801-15
(PostgreSQL: Multiple vulnerabilities)

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

Impact :

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 :

There is no known workaround for all these issues at this time.

Solution :

All PostgreSQL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose 'dev-db/postgresql'
