Red Hat Security Advisory
Synopsis: Low: mcstrans security and bug fix update
Advisory ID: RHSA-2007:0542-05
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0542.html
Issue date: 2007-11-07
Updated on: 2007-11-07
Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-4570
- ---------------------------------------------------------------------
1. Summary:
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
