=====================================================================
                   Red Hat Security Advisory

Synopsis:          Low: vsftpd security and bug fix update
Advisory ID:       RHSA-2008:0295-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2008-0295.html
Issue date:        2008-05-21
CVE Names:         CVE-2007-5962 
=====================================================================

1. Summary:

An updated vsftpd package that fixes a security issue and several bugs is
now available for Red Hat Enterprise Linux 5.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

The vsftpd package includes a Very Secure File Transfer Protocol (FTP)
daemon.

A memory leak was discovered in the vsftpd daemon. An attacker who is able
to connect to an FTP service, either as an authenticated or anonymous user,
could cause vsftpd to allocate all available memory if the "deny_file"
option was enabled in vsftpd.conf. (CVE-2007-5962)

As well, this updated package fixes following bugs:

* a race condition could occur even when the "lock_upload_files" option is
set. When uploading two files simultaneously, the result was a combination
of the two files. This resulted in uploaded files becoming corrupted. In
these updated packages, uploading two files simultaneously will result in a
file that is identical to the last uploaded file.

* when the "userlist_enable" option is used, failed log in attempts as a
result of the user not being in the list of allowed users, or being in the
list of denied users, will not be logged. In these updated packages, a new
"userlist_log=YES" option can be configured in vsftpd.conf, which will log
failed log in attempts in these situations.

* vsftpd did not support usernames that started with an underscore or a
period character. Usernames starting with an underscore or a period are
supported in these updated packages.

* using wildcards in conjunction with the "ls" command did not return all
the file names it should. For example, if you FTPed into a directory
containing three files -- A1, A21 and A11 -- and ran the "ls *1" command,
only the file names A1 and A21 were returned. These updated packages use
greedier code that continues to speculatively scan for items even after
matches have been found.

* when the "user_config_dir" option is enabled in vsftpd.conf, and the
user-specific configuration file did not exist, the following error
occurred after a user entered their password during the log in process:

500 OOPS: reading non-root config file

This has been resolved in this updated package.

All vsftpd users are advised to upgrade to this updated package, which
resolves these issues.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  

This update is available via Red Hat Network.  Details on how to use 
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bugs fixed (http://bugzilla.redhat.com/):

240553 - vsftpd has a create/lock race condition which corrupts uploads
392181 - vsftpd file listing issue with wildcard
392231 - Uploaded file corrupted when two connections from same client uploading same file simultaneously
397011 - CVE-2007-5962 vsftpd: memory leak when deny_file option is set

Advisory ID:       RHSA-2008:0297-02
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2008-0297.html

CVE Names:         CVE-2007-2231 CVE-2007-4211 CVE-2007-6598 
                   CVE-2008-1199 
=====================================================================

1. Summary:

An updated dovecot package that fixes several security issues and various
bugs is now available for Red Hat Enterprise Linux 5.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

Dovecot is an IMAP server for Linux and UNIX-like systems, primarily
written with security in mind.

A flaw was discovered in the way Dovecot handled the "mail_extra_groups"
option. An authenticated attacker with local shell access could leverage
this flaw to read, modify, or delete other users mail that is stored on
the mail server. (CVE-2008-1199)

This issue did not affect the default Red Hat Enterprise Linux 5 Dovecot
configuration. This update adds two new configuration options --
"mail_privileged_group" and "mail_access_groups" -- to minimize the usage
of additional privileges.

A directory traversal flaw was discovered in Dovecot's zlib plug-in. An
authenticated user could use this flaw to view other compressed mailboxes
with the permissions of the Dovecot process. (CVE-2007-2231)

A flaw was found in the Dovecot ACL plug-in. User with only insert
permissions for a mailbox could use the "COPY" and "APPEND" commands to set
additional message flags. (CVE-2007-4211)

A flaw was found in a way Dovecot cached LDAP query results in certain
configurations. This could possibly allow authenticated users to log in as
a different user who has the same password. (CVE-2007-6598)

As well, this updated package fixes the following bugs:

* configuring "userdb" and "passdb" to use LDAP caused Dovecot to hang. A
segmentation fault may have occurred. In this updated package, using an
LDAP backend for "userdb" and "passdb" no longer causes Dovecot to hang.

* the Dovecot "login_process_size" limit was configured for 32-bit systems.
On 64-bit systems, when Dovecot was configured to use either IMAP or POP3,
the log in processes crashed with out-of-memory errors. Errors such as the
following were logged:

pop3-login: pop3-login: error while loading shared libraries:
libsepol.so.1: failed to map segment from shared object: Cannot allocate
memory

In this updated package, the "login_process_size" limit is correctly
configured on 64-bit systems, which resolves this issue.

Note: this updated package upgrades dovecot to version 1.0.7. For
further details, refer to the Dovecot changelog:
http://koji.fedoraproject.org/koji/buildinfo?buildID=23397

Users of dovecot are advised to upgrade to this updated package, which
resolves these issues.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  

This update is available via Red Hat Network.  Details on how to use 
the Red Hat Network to apply this update are available at

245249 - Dovecot hangs while using ldap backend.

1. 给邮件增加 \Deleted 标记，表示已删除；
2. 使用 EXPUNGE 命令实际删除邮件；

1. 将 Inbox（收件夹）、Sent（已发邮件）等邮件夹里的邮件复制到 Trash（回收站） 邮件夹；
2. 将邮件打上 \Deleted 标记；
3. 将邮件从 Inbox, Sent 目录删除；
4. （也许后期再使用 'Clean Trash（清空回收站）'的功能删除回收站里的邮件）

May 20 16:36:54 rh3 postfix/smtpd[1938]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 553 5.7.1 <postmaster@a.cn>: Sender address rejected: not logged in; from=<postmaster@a.cn> to=<b@a.cn> proto=ESMTP helo=<rh3>

*) 怎样才算是新建了一个用户？
  用户存在与否，以 MySQL/LDAP 里是否有这个条目为准。
  如果数据库里有这个用户的信息，即表示这个用户是实际存在的。

*) 这里的“新建邮箱”是什么意思？
  这里的“新建邮箱”，是通过发送邮件给新用户，由 Postfix 收下邮件后将邮件转交给 MDA 这一层的工具，
  再由 MDA 工具在文件系统上创建实际的邮箱目录。例如你的收件夹、垃圾箱等；

*) 为什么发送邮件被拒绝？
  rhms 对发件人、收件人做了严格的控制。例如：

    + 邮件头中的 From 地址必须是 SASL 验证的用户名。这可以避免你的用户冒充别人发送垃圾邮件。
    + 邮件头中的 To 地址必须是你本地实际有的用户。这可以避免收下垃圾邮件。

  对于发件人、收件人限制，请参考 Postfix 的 main.cf 配置文件中的 'smtpd_sender_login_maps'
  以及 smtpd_recipient_restrictions 参数；

1) 新建用户时不要勾上“新建邮箱”这个选项；
2) 将 PostfixAdmin 目录下的 create_mailbox.php 文件的第 85 行注释掉：

   //if (isset ($_POST['fMail'])) $fMail = escape_string ($_POST['fMail']);

$CONF['quota_multiplier'] = 10240;
