Description

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_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."
