RHEL 5 : mcstrans (RHSA-2007:0542)

medium Nessus Plugin ID 27830

Synopsis

The remote Red Hat host is missing a security update for mcstrans.

Description

The remote Redhat Enterprise Linux 5 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2007:0542 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL mcstrans package based on the guidance in RHSA-2007:0542.
