Title: Novell Netware NWFTPD Username Format String Vulnerability
Severity: HIGH
Description:
Netware is a commercially available operating system distributed by Novell.
A problem with NWFTPD could make it possible for users to deny service to legitimate users of the service.
Under some circumstances, it may be possible to remotely crash a NWFTPD server. NWFTPD reacts unpredictably when it receives format strings in the form of usernames. This could ultimately result in users of the FTP server being unable to access data stored on the server.
It is unknown whether this format string vulnerability could be exploited to gain elevated privileges. In the event of an exploitable format string, an attacker could take advantage of this vulnerability to execute arbitrary code. This code would be executed with the privileges of the NWFTPD server, and could result in an attacker gaining remote access to the system with comparable privileges. This problem may affect previous versions of the software.
Affected Products:
- Novell Netware 6.0.0 SP1
