RHSA-2013:1866 - Security Advisory

Topic

An updated ca-certificates package that fixes one security issue is now
available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate
security impact.

Description

This package contains the set of CA certificates chosen by the Mozilla
Foundation for use with the Internet Public Key Infrastructure (PKI).

It was found that a subordinate Certificate Authority (CA) mis-issued an
intermediate certificate, which could be used to conduct man-in-the-middle
attacks. This update renders that particular intermediate certificate as
untrusted. (BZ#1038894)

All users should upgrade to this updated package. After installing the
update, all applications using the ca-certificates package must be
restarted for the changes to take effect.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
