Synopsis: Moderate: nss and nspr security, bug fix, and enhancement update
Issue Date: 2012-07-17
CVE Numbers: CVE-2012-0441

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.

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.
(CVE-2012-0441)

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: The above 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.

In addition, the nspr package has been upgraded to upstream version 4.9.1,
and the nss package has been upgraded to upstream version 3.13.5. These
updates provide a number of bug fixes and enhancements over the previous
versions.

All NSS and NSPR users should upgrade to these updated packages, which
correct these issues and add these enhancements. After installing the
update, applications using NSS and NSPR must be restarted for the changes
to take effect.
