Red Hat: RHSA-2000:043-03 critical: nfs-utils root compromise
Summary
Summary
The rpc.statd daemon shipped in Red Hat Linux 6.0, 6.1, and 6.2contains a flaw that could lead to a remote root break-in.Version 0.1.9.1 of the nfs-utils package corrects the problem.Although there is no known exploit for the flaw in rpc.statd,Red Hat urges all users running rpc.statd to upgrade tothe new nfs-utils package.Users should note that in Red Hat Linux 6.0 and 6.1 the rpc.statddaemon was in the knfsd-clients package. The nfs-utils packagereplaces both the knfsd and knfsd-clients packages shipped inRed Hat Linux 6.0 and 6.1.On systems running a kernel older than 2.2.16-3, users shouldalso take this opportunity to upgrade to the latest kernelrelease.
Solution
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
After installing the new nfs-utils package, the rpc.statd service
must be restarted. To do this, run:
/etc/rc.d/init.d/nfslock restart
