Synopsis:	Low: gfs2-utils security and bug fix update
Issue date:	2009-09-02
CVE Names:	CVE-2008-6552

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.
