- 漏洞描述

Novell NetWare and Novell Open Enterprise Server contains a flaw that may allow a malicious user to force server to negotiate a less secure SSL connection. The issue is triggered because SSL server implementation in NILE.NLM permits encryption with a NULL key, which results in cleartext communication. It is possible that the flaw may allow remote attackers to read an SSL protected session resulting in a loss of confidentiality.
