RHBA-2012:1124 - Bug Fix Advisory

Topic

Updated gvfs packages that fix multiple bugs are now available for Red Hat
Enterprise Linux 6.

Description

GVFS is the GNOME desktop's virtual file system layer, which allows users to
easily access local and remote data, including via the FTP, SFTP, WebDAV, CIFS
and SMB protocols, among others. GVFS integrates with the GIO (GNOME I/O)
abstraction layer.

This update fixes the following bugs:

• Previously, rules for ignoring mounts were too restrictive. If the user

clicked on an encrypted volume in the Nautilus' sidebar, an error message was
displayed and the volume could not be accessed. The underlying source code now
contains additional checks so that encrypted volumes have proper mounts
associated (if available), and the file system can be browsed as
expected.(BZ#599055)

• Due to a bug in the kernel, a freshly formatted Blu-ray Disk Rewritable

(BD-RE) medium contains a single track with invalid data that covers the whole
medium. This empty track was previously incorrectly detected, causing the drive
to be unusable for certain applications, such as Brasero. This update adds a
workaround to detect the empty track, so that freshly formatted BD-RE media are
properly recognized as blank. (BZ#669526)

• The code of the gvfs-info, gvfs-open, gvfs-cat, gvfs-ls and gvfs-mount

utilities contained hard-coded exit codes. This caused the utilities to always
return zero on exit. The exit codes have been revised so that the mentioned gvfs
utilities now return proper exit codes. (BZ#682799, BZ#746977, BZ#746978,
BZ#749369, BZ#749371, BZ#749372)

• When running gvfs-set-attribute with an invalid command-line argument

specified, the utility terminated unexpectedly with a segmentation fault. The
underlying source code has been modified so that the utility now prints a proper
error message when an invalid argument is specified. (BZ#746905)

• Due to missing object cleanup calls, the gvfsd daemon could use excessive

amount of memory, which caused the system to become unresponsive. Proper object
cleanup calls have been added with this update, which ensures that the memory
consumption is constant and the system does not hang in this scenario.
(BZ#809708)

All users of gvfs are advised to upgrade to these updated packages, which fix
these bugs.
