RHBA-2012:0919 - mod_nss bug fix update

Synopsis

mod_nss bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

An updated mod_nss package that fixes several 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:

  • PK11_ListCerts was called for every server instead of only once. If there were more than a few hundred certificates in the database, the PK11_ListCerts call could take several seconds or even minutes. (BZ#749408)

  • ECC is now enabled by default for mod_nss. (BZ#749409)

  • The fix for BZ#691502, related to clearing the SSL cache when mod_nss started, introduced a file descriptor leak in the httpd Apache daemon. This has been fixed. (BZ#797326 and BZ#797358)

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 Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
