An updated mcstrans package that fixes a security issue and a bug is now
This update has been rated as having low security impact by the CentOS
Security Response Team.
mcstrans is the translation daemon used on SELinux machines to translate
program context into human readable form.
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.
Users of mcstrans are advised to upgrade to this updated package, which
resolves this issue.
