squirrelmail-1.4.8-5.7AXS3

SquirrelMail is a standards-based webmail package written in PHP4. It includes built-in pure PHP support for the IMAP and SMTP protocols, and all pages render in pure HTML 4.0 (with no Javascript) for maximum compatibility across browsers. It has very few requirements and is very easy to configure and install. SquirrelMail has all the functionality you would want from an email client, including strong MIME support, address books, and folder manipulation.
Fixed bugs:
CVE-2009-1578
Multiple cross-site scripting (XSS) vulnerabilities in SquirrelMail before 1.4.18 allow remote attackers to inject arbitrary web script or HTML via vectors involving (1) certain encrypted strings in e-mail headers, related to contrib/decrypt_headers.php; (2) PHP_SELF; and (3) the query string (aka QUERY_STRING).
CVE-2009-1579
The map_yp_alias function in functions/imap_general.php in SquirrelMail before 1.4.18 allows remote attackers to execute arbitrary commands via shell metacharacters in a username string that is used by the ypmatch program.
CVE-2009-1581
functions/mime.php in SquirrelMail before 1.4.18 does not protect the application's content from Cascading Style Sheets (CSS) positioning in HTML e-mail messages, which allows remote attackers to spoof the user interface, and conduct cross-site scripting (XSS) and phishing attacks, via a crafted message.
