RHBA-2016:2967 - Bug Fix Advisory

Topic

Updated nfs-utils packages that fix one bug are now available for Red Hat Enterprise Linux 7.2 Extended Update Support.

Description

The nfs-utils packages provide a daemon for the kernel Network File System (NFS) server and related tools, which provides better performance than the traditional Linux NFS server used by most users. These packages also contain the mount.nfs, umount.nfs, and showmount programs.

This update fixes the following bug:

• Due to an incorrectly used variable in the find_keytab_entry() function, the rpc.gssd service terminated unexpectedly with a segmentation fault when reading the /etc/krb5.keytab file. A patch has been applied to fix this bug, and rpc.gssd no longer crashes in the described situation. (BZ#1368371)

Users of nfs-utils are advised to upgrade to these updated packages, which fix this bug. After installing this update, the nfs service will be restarted automatically.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.
