Vulnerability Note VU#203214

SquirrelMail may allow execution of arbitrary code

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 required) 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.

Information for obtaining updates may be found in the "Vendor" section of this note. Users may also visit the SquirrelMail web site for additional information concerning updates.

Note: SquirrelMail 1.2.6 is the only version affected and is from the previous stable release series. The current 1.4.x branch is not affected.
