Synopsis:	Low: mcstrans security and bug fix update
Issue date:	2007-11-07
CVE Names:	CVE-2007-4570

An algorithmic complexity weakness was found in the way the mcstrans 
daemon handled ranges of compartments in sensitivity labels. A local 
user could trigger this flaw causing mctransd to temporarily stop 
responding to other requests; a partial denial of service.  (CVE-2007-4570)

This update also fixes a problem where the mcstrans daemon was 
preventing SSH connections into an SELinux box, that was running a 
Multi-Level Security (MLS) Policy with multiple categories

SL 5.x
