Among the components provided by Services for Unix (SFU) 2.0 are services that implement the NFS (Network File System) and Telnet protocols. Both services contain memory leaks that could be triggered by a user request. An attacker who repeatedly sent such a request could deplete the kernel memory on the server to the point where
performance slowed and the system could potentially fail.
