XSS was discovered in SquirrelMail through 1.4.22
Summary
XSS was discovered in SquirrelMail through 1.4.22. Due to improper handling of
RCDATA and RAWTEXT type elements, the built-in sanitization mechanism can be
bypassed. Malicious script content from HTML e-mail can be executed within the
application context via crafted use of (for example) a NOEMBED, NOFRAMES,
NOSCRIPT, or TEXTAREA element ().
An unsafe use of unserialize() in compose.php has also been fixed.
