Debian: nfs-util denial of service fix
Posted by Joe Shakespeare   
Debian SGI has discovered that rpc.statd from the nfs-utils package, the Network Status Monitor, did not ignore the "SIGPIPE". Hence, a client prematurely terminating the TCP connection could also terminate the server process.

Package        : nfs-utils
Vulnerability  : wrong signal handler
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-1014

SGI has discovered that rpc.statd from the nfs-utils package, the
Network Status Monitor, did not ignore the "SIGPIPE".  Hence, a client
prematurely terminating the TCP connection could also terminate the
server process.

For the stable distribution (woody) this problem has been fixed in
version 1.0-2woody2.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your nfs-utils package.


Upgrade Instructions
--------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
