Subject: Medium security hole affecting Festival on Debian
	unstable/testing and Ubuntu Hardy Heron

It has been recently been identified that the Festival text to speech server 
was vulnerable to unauthenticated remote code execution.  Further research 
indicated that this vulnerability has already been reported as a local 
privilege escalation against both the Gentoo and SuSE GNU/Linux distributions 
and had assigned CVE-2007-4074.  The remote form of this vulnerability was 
originally identified in the default configuration of Festival 1.96~beta-5 as 
distributed in Debian unstable but Ubuntu Hardy Heron was also affected. Both 
Debian and Ubuntu have since released patches to resolve this flaw.  An 
advisory for this flaw which provides further information is attached.  A 
short analysis of Debian's response can be found at 
http://www.nth-dimension.org.uk/blog.php?id=68.

Cheers,
Tim
