RedHat Update for cifs-utils RHSA-2012:0902-04

Please Install the Updated Packages.
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 &quot /etc/mtab&quot 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 &quot /etc/mtab&quot 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 &quot uid&quot , &quot gid&quot or &quot cruid&quot 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 &quot 0&quot 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 &quot domain_realm&quot section in the &quot krb5.conf&quot 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 ... Description truncated, for more information please check the Reference URL
