The remote NFS daemon is prone to a denial of service attack.
The remote host is running knfsd, a kernel NFS daemon.
There is a vulnerability in this version that may allow an attacker to
cause a kernel panic on the remote host by sending a malformed GETATTR
request with an invalid length field.
See also :
Upgrade to Linux kernel version 2.4.21 (or later) as the issue
reportedly has been silently patched in that version.
