Samba netdfs_io_dfs_EnumInfo_d Heap Overflow Vulnerability

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Samba. User interaction is not required to exploit this vulnerability. The specific flaw exists in the parsing of RPC requests to the DFS RPC interface. When parsing a request to DFSEnum, heap allocation is calculated based on user input. By specifying invalid values, heap blocks can be overwritten leading to remote code execution.
