Topic

An updated mod_revocator package that fixes multiple bugs is now available for
Red Hat Enterprise Linux 6.

Description

The mod_revocator module retrieves and installs remote Certificate Revocation
Lists (CRLs) into an Apache web server.

This update fixes the following bugs:

  • Previously, the code for the httpd daemon shutdown was incorrect and the

mod_revocator module did not shut down the httpd daemon when CRL (Certificate
Revocation List) update failed on IA-32 architectures. With this update, the
code has been fixed and httpd is now closed as expected when CRL update fails.
(BZ#748579)

  • Previously, the code for httpd shutdown was incorrect and the mod_revocator

module did not shut down the httpd daemon when expired CRLs were fetched. With
this update, the code has been fixed and httpd is closed as expected in this
scenario. (BZ#748577)

  • Due to an incorrect initialization size of a static array, the httpd daemon

with mod_revocator failed to start on 64-bit PowerPC architectures. With this
update, the size of the array has been modified and the httpd starts as expected
under these circumstances. (BZ#749696)

  • The httpd daemon with the mod_revocator module cannot be used as an HTTP

client by default because the SELinux policy prevents such behavior. However, to
acquire CRLs from a remote host, the httpd daemon needs to behave as an HTTP
client to send HTTP messages to the host. If the behavior was not enabled, child
processes of the httpd daemon terminated unexpectedly with segmentation faults
when attempting to connect to a remote host. With this update, the underlying
code has been changed and the segmentation faults no longer occur.

Note: To change the SELinux policy and enable httpd to request CRLs from a
remote host, execute the "setsebool -P httpd_can_network_connect=1" command as
root. (BZ#746365)

All users of mod_revocator are advised to upgrade to this updated package, which
fixes these bugs.

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
