SquirrelMail is a standards-based webmail package written in PHP.
Multiple vulnerabilities were found in SquirrelMail:
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>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,
<li>Tomas Hoger discovered an unspecified session fixation
vulnerability (CVE-2009-1580).
<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).
<impact type="high">
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.
There is no known workaround at this time.
All SquirrelMail users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=mail-client/squirrelmail-1.4.19&quot;</code>
