Sun Network Security Services (NSS) vulnerable to DoS due to an unspecified vulnerability

Original Release date: 09 Feb 2007 | Last revised: 09 Feb 2007


The NSS libraries used in the Sun One Application Server and the Sun Java System web server contain an unspecified vulnerability that may allow an attacker to create a denial-of-service condition.


The Sun One Application Server provides a Java 2 Platform for delivering Java applications and Web services. The Sun Java System web server is a web server that can run on multiple operating systems. Network Security Services (NSS) are a set of libraries that support the development of security enabled applications.

An unspecified vulnerability exists in NSS libraries used by the Sun Java System Web Server and the Sun ONE Application Server.

From Sun document ID 102670:

    A local or remote unprivileged user may be able to cause the Sun Java System Web Server or the Sun ONE Application Server to exit unexpectedly due to a security vulnerability in Network Security Services (NSS). The ability to disable a Sun Java System Web Server or a Sun ONE Application Server is a type of Denial of Service (DoS).


A remote, unauthenticated attacker may be able to create a denial of service condition.


Sun has released updates to address this issue. See Sun Java System Web Server 6.0 Service Pack 10 or Sun ONE Application Server 7 Update for more details.
