Topic

An updated gfs2-utils package that fixes multiple security issues and
various bugs is now available for Red Hat Enterprise Linux 5.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

Description

The gfs2-utils package provides the user-space tools necessary to mount,
create, maintain, and test GFS2 file systems.

Multiple insecure temporary file use flaws were discovered in GFS2 user
level utilities. A local attacker could use these flaws to overwrite an
arbitrary file writable by a victim running those utilities (typically
root) with the output of the utilities via a symbolic link attack.
(CVE-2008-6552)

This update also fixes the following bugs:

  • gfs2_fsck now properly detects and repairs problems with sequence numbers

on GFS2 file systems.

  • GFS2 user utilities now use the file system UUID.
  • gfs2_grow now properly updates the file system size during operation.
  • gfs2_fsck now returns the proper exit codes.
  • gfs2_convert now properly frees blocks when removing free blocks up to

height 2.

  • the gfs2_fsck manual page has been renamed to fsck.gfs2 to match current

standards.

  • the 'gfs2_tool df' command now provides human-readable output.
  • mounting GFS2 file systems with the noatime or noquota option now works

properly.

  • new capabilities have been added to the gfs2_edit tool to help in testing

and debugging GFS and GFS2 issues.

  • the 'gfs2_tool df' command no longer segfaults on file systems with a

block size other than 4k.

  • the gfs2_grow manual page no longer references the '-r' option, which has

been removed.

  • the 'gfs2_tool unfreeze' command no longer hangs during use.
  • gfs2_convert no longer corrupts file systems when converting from GFS to

GFS2.

  • gfs2_fsck no longer segfaults when encountering a block which is listed

as both a data and stuffed directory inode.

  • gfs2_fsck can now fix file systems even if the journal is already locked

for use.

  • a GFS2 file system's metadata is now properly copied with 'gfs2_edit

savemeta' and 'gfs2_edit restoremeta'.

  • the gfs2_edit savemeta function now properly saves blocks of type 2.
  • 'gfs2_convert -vy' now works properly on the PowerPC architecture.
  • when mounting a GFS2 file system as '/', mount_gfs2 no longer fails after

being unable to find the file system in '/proc/mounts'.

  • gfs2_fsck no longer segfaults when fixing 'EA leaf block type' problems.

All gfs2-utils users should upgrade to this updated package, which resolves
these issues.

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
