Squirrelmail: Another XSS vulnerability

Squirrelmail: Another XSS vulnerability Squirrelmail fails to properly sanitize user input, which could lead to a compromise of webmail accounts. Squirrelmail 2004-06-15 2006-05-22 52434 remote 1.4.3 1.4.3_rc1-r1

SquirrelMail is a webmail package written in PHP. It supports IMAP and SMTP, and can optionally be installed with SQL support.

A new cross-site scripting (XSS) vulnerability in Squirrelmail-1.4.3_rc1 has been discovered. In functions/mime.php Squirrelmail fails to properly sanitize user input.

By enticing a user to read a specially crafted e-mail, an attacker can execute arbitrary scripts running in the context of the victim's browser. This could lead to a compromise of the user's webmail account, cookie theft, etc.

There is no known workaround at this time.

All SquirrelMail users should upgrade to the latest stable version:


    # emerge sync
    
    # emerge -pv ">=mail-client/squirrelmail-1.4.3"
    # emerge ">=mail-client/squirrelmail-1.4.3"
