Test ID:1.3.6.1.4.1.25623.1.0.870765
Category:Red Hat Local Security Checks
Title:RedHat Update for nss, nss-util, and nspr RHSA-2012:0973-04
Summary:The remote host is missing an update for the 'nss, nss-util, and nspr'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'nss, nss-util, and nspr'
package(s) announced via the referenced advisory.

Vulnerability Insight:
Network Security Services (NSS) is a set of libraries designed to support
the cross-platform development of security-enabled client and server
applications. Netscape Portable Runtime (NSPR) provides platform
independence for non-GUI operating system facilities.

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.
(BZ#798533)

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.

The nspr package has been upgraded to upstream version 4.9, which provides
a number of bug fixes and enhancements over the previous version.
(BZ#799193)

The nss-util package has been upgraded to upstream version 3.13.3, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#799192)

The nss package has been upgraded to upstream version 3.13.3, which
provides numerous bug fixes and enhancements over the previous version. In
particular, SSL 2.0 is now disabled by default, support for SHA-224 has
been added, PORT_ErrorToString and PORT_ErrorToName now return the error
message and symbolic name of an NSS error code, and NSS_GetVersion now
returns the NSS version string. (BZ#744070)

These updated nss, nss-util, and nspr packages also provide fixes for the
following bugs:

* 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#746632)

* 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#761086)

* The PEM module did not fully initialize newly constructed objects with
function pointers set to NULL. Consequ ...
