squirrelmail security update

CentOS Errata and Security Advisory CESA-2006:0283

SquirrelMail is a standards-based webmail package written in PHP4.

A bug was found in the way SquirrelMail presents the right frame to the
user. If a user can be tricked into opening a carefully crafted URL, it is
possible to present the user with arbitrary HTML data. (CVE-2006-0188)

A bug was found in the way SquirrelMail filters incoming HTML email. It is
possible to cause a victim’s web browser to request remote content by
opening a HTML email while running a web browser that processes certain
types of invalid style sheets. Only Internet Explorer is known to process
such malformed style sheets. (CVE-2006-0195)

A bug was found in the way SquirrelMail processes a request to select an
IMAP mailbox. If a user can be tricked into opening a carefully crafted
URL, it is possible to execute arbitrary IMAP commands as the user viewing
their mail with SquirrelMail. (CVE-2006-0377)

Users of SquirrelMail are advised to upgrade to this updated package, which
contains SquirrelMail version 1.4.6 and is not vulnerable to these issues.
