Updated nss and nspr packages that fix two security issues, several bugs,
and add various enhancements are now available for Red Hat
Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.
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.
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 BZ#798533 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
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. (BZ#834220, BZ#834219)
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.
