Security Fix

BZ#798533

It was found that a Certificate Authority (CA) issued a subordinate CA certificate to its customer, that could be used to issue certificates for any name. This update renders the subordinate CA certificate as untrusted.

Note

This fix only applies to applications using the NSS Builtin Object Token. It does not render the certificates untrusted for applications that use the NSS library, but do not use the NSS Builtin Object Token.

BZ#746632

A PEM module internal function did not clean up memory when detecting a non-existent file name. Consequently, memory leaks in client code occurred. The code has been improved to deallocate such temporary objects and as a result the reported memory leakage is gone.

BZ#761086

Recent changes to NSS re-introduced a problem where applications could not use multiple SSL client certificates in the same process. Therefore, any attempt to run commands that worked with multiple SSL client certificates, such as the "yum repolist" command, resulted in a re-negotiation handshake failure. With this update, a revised patch correcting this problem has been applied to NSS, and using multiple SSL client certificates in the same process is now possible again.

BZ#768669

The PEM module did not fully initialize newly constructed objects with function pointers set to NULL. Consequently, a segmentation violation in libcurl was sometimes experienced while accessing a package repository. With this update, the code has been changed to fully initialize newly allocated objects. As a result, updates can now be installed without problems.

BZ#784674

A lack-of-robustness flaw caused the administration server for Red Hat Directory Server to terminate unexpectedly because the mod_nss module made nss calls before initializing nss as per the documented API. With this update, nss protects itself against being called before it has been properly initialized by the caller.

BZ#795693

Compilation errors occurred with some compilers when compiling code against NSS 3.13.1. The following error message was displayed:

pkcs11n.h:365:26: warning: "__GNUC_MINOR" is not defined

An upstream patch has been applied to improve the code and the problem no longer occurs.

BZ#797426

Unexpected terminations were reported in the messaging daemon (qpidd) included in Red Hat Enterprise MRG after a recent update to nss. This occurred because qpidd made nss calls before initializing nss. These updated packages prevent qpidd and other affected processes that call nss without initializing as mandated by the API from crashing.

Security Fix

CVE-2012-0441

A flaw was found in the way the ASN.1 (Abstract Syntax Notation One) decoder in NSS handled zero length items. This flaw could cause the decoder to incorrectly skip or replace certain items with a default value, or could cause an application to crash if, for example, it received a specially-crafted OCSP (Online Certificate Status Protocol) response.

Security Fix

BZ#890605

It was found that a Certificate Authority (CA) mis-issued two intermediate certificates to customers. These certificates could be used to launch man-in-the-middle attacks. This update renders those certificates as untrusted. This covers all uses of the certificates, including SSL, S/MIME, and code signing.

Note

This fix only applies to applications using the NSS Builtin Object Token. It does not render the certificates untrusted for applications that use the NSS library, but do not use the NSS Builtin Object Token.
