    Package        : squirrelmail
    Vulnerability  : cross-site scripting
    Problem-Type   : remote
    Debian-specific: no
    CVE IDs        : CVE-2006-6142
    
    Martijn Brinkers discovered cross-site scripting vulnerabilities in the
    the mailto parameter of webmail.php, the session and delete_draft
    parameters of compose.php and through a shortcoming in the magicHTML
    filter. An attacker could abuse these to execute malicious JavaScript in
    the user's webmail session. 
    
    Also, a workaround was made for Internet Explorer <= 5: IE will attempt
    to guess the MIME type of attachments based on content, not the MIME 
    header sent. Attachments could fake to be an 'harmless' JPEG, while they
    were in fact HTML that Internet Explorer would render.
    
    For the stable distribution (sarge) these problems have been fixed in
    version 2:1.4.4-10.
    
    For the upcoming stable distribution (etch) these problems have been fixed
    in version 2:1.4.9a-1.
    
    For the unstable distribution (sid) these problems have been fixed in
    version 2:1.4.9a-1.
    
    We recommend that you upgrade your squirrelmail package.
