Detail
Problem Description: An updated mcstrans package that fixes a security issue and a bug is now available. This update has been rated as having low security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 3. Problem description: 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188 5. Bug IDs fixed (http://bugzilla.redhat.com/): 228398 - LSPP: Not able to ssh into the machine with multiple categories 288201 - CVE-2007-4570 mctransd DoS |
