>+	A vulnerability has been discovered in Sympa web interface by which attacker can
>+	 execute arbitrary code with root privileges.
>+	Sympa uses two sorts of setuid wrappers:
>+	 <ul><li>FastCGI wrappers</li>
>+	 <li>newaliases wrapper</li></ul>
>+ The FastCGI wrappers (wwsympa-wrapper.fcgi and sympa_soap_server-wrapper.fcgi)
>+	were used to make the web interface running under privileges of a
>+	dedicated user.
>+	The newaliases wrapper (sympa_newaliases-wrapper) allows Sympa to update the
>+	alias database with root privileges.
>+	Since these setuid wrappers did not clear environment variables,
>+	if environment variables like PERL5LIB were injected,
>+	forged code might be loaded and executed under privileges of setuid-ed
>+	users.
