Subject Name: WordPress
Subject Summary: Weblog Publishing System
Subject Home: http://wordpress.org/
Subject Versions: * <= 2.0.5

Vulnerability Id: none
Vulnerability Scope: global (not OpenPKG specific)

Attack Feasibility: run-time
Attack Vector: remote network
Attack Impact: privilege escalation, arbitrary code execution

Description:
According to a security advisory from Stefan Esser [0], a
vulnerability exists in the Weblog publishing system WordPress
[1], versions up to and including 2.0.5. WordPress supports
decoding Trackbacks with different charsets when PHP's
"mbstring" extension is activated (OpenPKG packages "php"
build with option "with_mbstring=yes" or "apache" build with
"with_mod_php_mbstring=yes"). Because the decoding happens after the
database escaping is performed, choosing a suitable charset for the
input data allows bypassing the protection against SQL injection.
