RHEL 5 : gfs2-utils (RHSA-2009:1337)

medium Nessus Plugin ID 40839

Synopsis

The remote Red Hat host is missing a security update for gfs2-utils.

Description

The remote Redhat Enterprise Linux 5 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2009:1337 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL gfs2-utils package based on the guidance in RHSA-2009:1337.
