Test ID:1.3.6.1.4.1.25623.1.0.870873
Category:Red Hat Local Security Checks
Title:RedHat Update for quota RHSA-2013:0120-01
Summary:The remote host is missing an update for the 'quota'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'quota'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The quota package provides system administration tools for monitoring
and limiting user and group disk usage on file systems.

It was discovered that the rpc.rquotad service did not use tcp_wrappers
correctly. Certain hosts access rules defined in '/etc/hosts.allow' and
'/etc/hosts.deny' may not have been honored, possibly allowing remote
attackers to bypass intended access restrictions. (CVE-2012-3417)

This issue was discovered by the Red Hat Security Response Team.

This update also fixes the following bugs:

* Prior to this update, values were not properly transported via the remote
procedure call (RPC) and interpreted by the client when querying the quota
usage or limits for network-mounted file systems if the quota values were
2^32 kilobytes or greater. As a consequence, the client reported mangled
values. This update modifies the underlying code so that such values are
correctly interpreted by the client. (BZ#667360)

* Prior to this update, warnquota sent messages about exceeded quota limits
from a valid domain name if the warnquota tool was enabled to send warning
e-mails and the superuser did not change the default warnquota
configuration. As a consequence, the recipient could reply to invalid
addresses. This update modifies the default warnquota configuration to use
the reserved example.com. domain. Now, warnings about exceeded quota limits
are sent from the reserved domain that inform the superuser to change to
the correct value. (BZ#680429)

* Previously, quota utilities could not recognize the file system as having
quotas enabled and refused to operate on it due to incorrect updating of
/etc/mtab. This update prefers /proc/mounts to get a list of file systems
with enabled quotas. Now, quota utilities recognize file systems with
enabled quotas as expected. (BZ#689822)

* Prior to this update, the setquota(8) tool on XFS file systems failed
to set disk limits to values greater than 2^31 kilobytes. This update
modifies the integer conversion in the setquota(8) tool to use a 64-bit
variable big enough to store such values. (BZ#831520)

All users of quota are advised to upgrade to this updated package, which
contains backported patches to resolve these issues.

Affected Software/OS:
quota on Red Hat Enterprise Linux (v. 5 server)
