Moderate: nss, nspr, and nss-util security, bug fix, and enhancement update
Security Advisory: Moderate
Updated nss, nss-util, and nspr packages that fix one security issue,
several bugs, and add various enhancements are now available for Red Hat
Enterprise Linux 6.
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.
