"An updated squirrelmail package that fixes a local file disclosure
flaw is now available.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

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

A local file disclosure flaw was found in the way SquirrelMail loads
plugins. In SquirrelMail 1.4.6 or earlier, if register_globals is on
and magic_quotes_gpc is off, it became possible for an unauthenticated
remote user to view the contents of arbitrary local files the web
server has read-access to. This configuration is neither default nor
safe, and configuring PHP with the register_globals set on is
dangerous and not recommended. (CVE-2006-2842)

Users of SquirrelMail should upgrade to this erratum package, which
contains a backported patch to correct this issue."
