RHBA-2012:0394 - Bug Fix Advisory

Topic

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

Description

The mod_nss module provides strong cryptography for the Apache HTTP Server via
the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols,
using the Network Security Services (NSS) security library.

This update fixes the following bugs:

• The RHBA-2011:1656 errata advisory released a patch that fixed a problem of

mod_nss crashing when clearing its SSL cache on startup without the NSS library
initialized. However, that patch placed the fix in the improper location in the
code, which caused a file descriptor leak in the Apache httpd daemon. With this
update, the necessary fix has been relocated to the appropriate location in the
code so that the problem is fixed and the file descriptor leak no longer occurs.
(BZ#800270, BZ#800271)

All users of mod_nss 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
