Id Description
9116 Netscape Network Security Services (NSS) Library SSLv2 Challenge Overflow

A remote overflow exists in the Network Security Services library. The library fails to validate the length of the "challenge" field during negotiation of the SSLv2 protocol. This library is used by many commercial and open-source products to provide SSL services. Affected applications include the Netscape Enterprise web server, the SunONE web, directory, and mail servers, and a large number of open-source application servers. Successful exploitation of this issue may result in arbitrary code execution with the privileges of the vulnerable service, leading to a lack of integrity.
