RHBA-2012:0783 - nfs4-acl-tools bug fix update

Synopsis

nfs4-acl-tools bug fix update

Type/Severity

Bug Fix Advisory

Topic

An updated nfs4-acl-tools package that fixes one bug is now available for Red Hat Enterprise Linux 6.

Description

The nfs4-acl-tools package provides utilities for managing NFSv4 Access Control Lists (ACLs) on files and directories mounted on ACL-enabled NFSv4 file systems.

This update fixes the following bug:

  • Prior to this update, several uninitialized stack pointers were incorrectly freed. As a consequence, the "nfs4_setfacl" command failed with the error message "*** glibc detected *** nfs4_setfacl: double free or corruption (out)" if the format of the input ACL file was incorrect. This update corrects the memory handling process. Now, the nfs4_setfacl command displays a useful error message if the input file syntax is invalid. (BZ#769862)

All users of nfs4-acl-tools are advised to upgrade to this updated package, which fixes this bug.

Solution

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

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
