SquirrelMail is a standards-based webmail package written in PHP.
Form submissions in SquirrelMail did not implement protection against
Cross-Site Request Forgery (CSRF) attacks. If a remote attacker tricked a
user into visiting a malicious web page, the attacker could hijack that
user's authentication, inject malicious content into that user's
preferences, or possibly send mail without that user's permission.
Users of SquirrelMail should upgrade to this updated package, which
contains a backported patch to correct these issues.
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
