The quota package was updated to fix an issue with tcp_wrappers, where hosts.allow/deny files would have not been correctly honored.
(CVE-2012-3417)

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 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.

  - 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.

  - 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.

  - 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.

An updated quota package that fixes one security issue and multiple bugs is now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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

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

quota was fixed to handle tcp wrappers in rquotad correctly.

The remote Redhat Enterprise Linux 4 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - quota: incorrect use of tcp_wrappers (CVE-2012-3417)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

The remote Oracle Linux 5 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2013-0120 advisory.

    - Fix CVE-2012-3417 (incorrect use of tcp_wrappers) (Resolves: #841448)

Tenable has extracted the preceding description block directly from the Oracle 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.
