Subject: Security ERRATA Low: squirrelmail on SL5.x (noarch)
Newsgroups: gmane.linux.scientific.errata
Date: Wednesday 16th January 2013 22:10:09 UTC (over 3 years ago)
Synopsis:          Low: squirrelmail security and bug fix update
Issue Date:        2013-01-08
CVE Numbers:       CVE-2012-2124
--

The SquirrelMail security update SLSA-2012:0103 did not, unlike the erratum
text stated, correct the CVE-2010-2813 issue, a flaw in the way
SquirrelMail
handled failed log in attempts. A user preference file was created when
attempting to log in with a password containing an 8-bit character, even 
if the
username was not valid. A remote attacker could use this flaw to eventually
consume all hard disk space on the target SquirrelMail server. 
(CVE-2012-2124)

This update also fixes the following bugs:

* Prior to this update, SquirrelMail could not decode multi-line subjects
properly. Consequently, the decode header internationalization option 
did not
properly handle new lines or tabs at the beginning of the lines. This 
bug has
been fixed and SquirrelMail now works correctly in the described scenario.

* Due to a bug, attachments written in HTML code on the Windows operating
system were not displayed properly when accessed with SquirrelMail; the
"!=null" string was trimmed to "!ull". This bug has been fixed and the
attachments are now displayed correctly in such a case.

* Previously, e-mail messages with a Unique Identifier (UID) larger than 
2^31
bytes were unreadable when using the squirrelmail package. With this 
patch the
squirrelmail package is able to read all messages regardless of the UIDs 
size.

* Due to a bug, a PHP script did not assign the proper character set to
requested variables. Consequently, SquirrelMail could not display any 
e-mails.
The underlying source code has been modified and now the squirrelmail 
package
assigns the correct character set.

* Due to the incorrect internationalization option located at the i18n.php
file, the squirrelmail package could not use the GB 2312 character set. The
i18n.php file has been fixed and the GB 2312 character set works 
correctly in
the described scenario.

* Previously, the preg_split() function contained a misspelled constant,
PREG_SPLIT_NI_EMPTY, which could cause SquirrelMail to produce error 
messages.
The name of the constant has been corrected to PREG_SPLIT_NO_EMPTY, and
SquirrelMail no longer produces error messages in this scenario.

* Due to Security-Enhanced Linux (SELinux) settings, sending e-mails 
from the
SquirrelMail web interface was blocked. This update adds a note to the
SquirrelMail documentation that describes how to set the SELinux options to
allow sending e-mails from the SquirrelMail web interface.

* Previously, the squirrelmail package did not comply with the RFC 2822
specification about line length limits. Consequently, attachments with
lines
longer than 998 characters could not be forwarded using SquirrelMail. This
patch modifies the underlying source code and now SquirrelMail complies
with
the RFC 2822 specification as expected.

* Prior to this update, the squirrelmail package required the php-common 
script
instead of the mod_php script during installation or upgrade of the
package,
which led to a dependency error. As a result, attempting to install or 
upgrade
the squirrelmail package failed on systems using the php53 packages. 
With this
update, the dependencies of the squirrelmail package were changed and the
installation or upgrade now works correctly in the described scenario.
