-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
Gerfried Fuchs uploaded new packages for postgresql-8.4 which fixed the
following security problem:
CVE-2010-3433
The PL/perl and PL/Tcl implementations in PostgreSQL 7.4 before 7.4.30,
8.0 before 8.0.26, 8.1 before 8.1.22, 8.2 before 8.2.18, 8.3 before
8.3.12, 8.4 before 8.4.5, and 9.0 before 9.0.1 do not properly protect
script execution by a different SQL user identity within the same
session, which allows remote authenticated users to gain privileges via
crafted script code in a SECURITY DEFINER function, as demonstrated by
(1) redefining standard functions or (2) redefining operators, a
different vulnerability than CVE-2010-1168, CVE-2010-1169,
CVE-2010-1170, and CVE-2010-1447.
