The remote Scientific Linux host is missing a security update.
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
- 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
- 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.
