A local attacker could use these flaws to overwrite anarbitrary file writable by a victim running those utilities (typicallyroot) 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 toheight 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 ablock 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_editsavemeta' 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.SL 5.x SRPMS:gfs2-utils-0.1.62-1.el5.src.rpm i386:gfs2-utils-0.1.62-1.el5.i386.rpm x86_64:gfs2-utils-0.1.62-1.el5.x86_64.rpm-Connie Sieh-Troy Dawson
