glibc-2.2 contains a local vulnerability that affects all setuid root

binaries.  Any user on affected systems will be able to read any file on

the system through a simple process:  The user sets the RESOLV_HOST_CONF

environment variable to the name of the file that they wish to read, then

runs any setuid root program that makes use of that variable.  The file is

then written to stderr.
