Synopsis :

The remote webmail application is affected by multiple issues.

Description :

The installed version of SquirrelMail fails to sanitize user-supplied
input to mailbox names before passing them to an IMAP server. An
unauthenticated attacker may be able to leverage this issue to launch
attacks against the underlying IMAP server or against a user's
mailboxes by tricking him into clicking on a specially-formatted link
in an email message.

There are also reportedly several possible cross-site scripting flaws
that could be exploited to inject arbitrary HTML and script code
into a user's browser.
