This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell NetStorage. Authentication is not required to exploit this vulnerability.

The specific flaws exists within the xsrvd process during the wide character conversion of requested file paths. In conjunction with a long username value the file path conversion will result in a heap overflow corrupting a chunk that will be immediately freed. This can be leveraged by remote attackers to compromise the NetStorage server.
