<description>
<p>
Multiple vulnerabilities were found in SquirrelMail:
</p>
<ul><li>Niels
Teusink reported multiple input sanitation flaws in certain encrypted
strings in e-mail headers, related to contrib/decrypt_headers.php,
PHP_SELF and the query string (aka QUERY_STRING) (CVE-2009-1578).
</li>
<li>Niels Teusink also reported that the map_yp_alias() function
in functions/imap_general.php does not filter shell metacharacters in a
username and that the original patch was incomplete (CVE-2009-1381,
CVE-2009-1579).
</li>
<li>Tomas Hoger discovered an unspecified session fixation
vulnerability (CVE-2009-1580).
</li>
<li>Luc Beurton reported that functions/mime.php does not protect
the application's content from Cascading Style Sheets (CSS) positioning
in HTML e-mail messages (CVE-2009-1581).
</li>
</ul>
</description>
<impact type="high">
<p>
The vulnerabilities allow remote attackers to execute arbitrary code
with the privileges of the user running the web server, to hijack web
sessions via a crafted cookie, to spoof the user interface and to
conduct Cross-Site Scripting and phishing attacks, via a specially
crafted message.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All SquirrelMail users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=mail-client/squirrelmail-1.4.19&quot;</code>
</resolution>
