|Summary:||The remote host is missing an update for the 'cifs-utils'; package(s) announced via the referenced advisory.|
The remote host is missing an update for the 'cifs-utils'
package(s) announced via the referenced advisory.
The cifs-utils package contains tools for mounting and managing shares on
Linux using the SMB/CIFS protocol. The CIFS shares can be used as standard
Linux file systems.
A file existence disclosure flaw was found in mount.cifs. If the tool was
installed with the setuid bit set, a local attacker could use this flaw to
determine the existence of files or directories in directories not
accessible to the attacker. (CVE-2012-1586)
Note: mount.cifs from the cifs-utils package distributed by Red Hat does
not have the setuid bit set. We recommend that administrators do not
manually set the setuid bit for mount.cifs.
This update also fixes the following bugs:
* The cifs.mount(8) manual page was previously missing documentation for
several mount options. With this update, the missing entries have been
added to the manual page. (BZ#769923)
* Previously, the mount.cifs utility did not properly update the
'/etc/mtab' system information file when remounting an existing CIFS
mount. Consequently, mount.cifs created a duplicate entry of the existing
mount entry. This update adds the del_mtab() function to cifs.mount, which
ensures that the old mount entry is removed from '/etc/mtab' before adding
the updated mount entry. (BZ#770004)
* The mount.cifs utility did not properly convert user and group names to
numeric UIDs and GIDs. Therefore, when the 'uid', 'gid' or 'cruid' mount
options were specified with user or group names, CIFS shares were mounted
with default values. This caused shares to be inaccessible to the intended
users because UID and GID is set to '0' by default. With this update, user
and group names are properly converted so that CIFS shares are now mounted
with specified user and group ownership as expected. (BZ#796463)
* The cifs.upcall utility did not respect the 'domain_realm' section in
the 'krb5.conf' file and worked only with the default domain.
Consequently, an attempt to mount a CIFS share from a different than the
default domain failed with the following error message:
mount error(126): Required key not available
This update modifies the underlying code so that cifs.upcall handles
multiple Kerberos domains correctly and CIFS shares can now be mounted as
expected in a multi-domain environment. (BZ#805490)
In addition, this update adds the following enhancements:
* The cifs.upcall util ...
