3. Description:
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.
