Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell Netware. Authentication is required to exploit this vulnerability.
The flaw exists within SSHD.NLM. When the application attempts to resolve an absolute path on the server, a 512 byte destination buffer is used without bounds checking.
