RedHat Update for nfs-utils RHSA-2012:0310-03

Please Install the Updated Packages.
The nfs-utils package provides a daemon for the kernel Network File System (NFS) server, and related tools such as the mount.nfs, umount.nfs, and showmount programs. It was found that the mount.nfs tool did not handle certain errors correctly when updating the mtab (mounted file systems table) file. A local attacker could use this flaw to corrupt the mtab file. (CVE-2011-1749) This update also fixes the following bugs: * The nfs service failed to start if the NFSv1, NFSv2, and NFSv4 support was disabled (the MOUNTD_NFS_V1=&quot no&quot , MOUNTD_NFS_V2=&quot no&quot MOUNTD_NFS_V3=&quot no&quot lines in /etc/sysconfig/nfs were uncommented) because the mountd daemon failed to handle the settings correctly. With this update, the underlying code has been modified and the nfs service starts successfully in the described scenario. (BZ#529588) * When a user's Kerberos ticket expired, the &quot sh rpc.gssd&quot messages flooded the /var/log/messages file. With this update, the excessive logging has been suppressed. (BZ#593097) * The crash simulation (SM_SIMU_CRASH) of the rpc.statd service had a vulnerability that could be detected by ISS (Internet Security Scanner). As a result, the rpc.statd service terminated unexpectedly with the following error after an ISS scan: rpc.statd[xxxx]: recv_rply: can't decode RPC message! rpc.statd[xxxx]: *** SIMULATING CRASH! *** rpc.statd[xxxx]: unable to register (statd, 1, udp). However, the rpc.statd service ignored SM_SIMU_CRASH. This update removes the simulation crash support from the service and the problem no longer occurs. (BZ#600497) * The nfs-utils init scripts returned incorrect status codes in the following cases: if the rpcgssd and rpcsvcgssd daemon were not configured, were provided an unknown argument, their function call failed, if a program was no longer running and a /var/lock/subsys/$SERVICE file existed, if starting a service under an unprivileged user, if a program was no longer running and its pid file still existed in the /var/run/ directory. With this update, the correct codes are returned in these scenarios. (BZ#710020) * The &quot nfsstat -m&quot command did not display NFSv4 mounts. With this update, the underlying code has been modified and the command returns the list of all mounts, including any NFSv4 mounts, as expected. (BZ#712438) * Previously, the nfs manual pages described the fsc mount option however, this option is not supported. This update removes the option description from the ma ...
