Gmane

Subject: Security ERRATA Low: quota on SL5.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Wednesday 16th January 2013 22:10:14 UTC (over 3 years ago)
Synopsis:          Low: quota security and bug fix update
Issue Date:        2013-01-08
CVE Numbers:       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.
